# How to assemble a floor fan Equation

## Fan of the floor of the three.Speed

The fan, like any other electrical device, has the ability to sometimes break, the stator winding most often burns in it. But this is not a reason to send him to retire. Within the framework of this article, let’s talk about the practice of repairing household fans.

We begin the process of disassembly by removing the fan cover, under it a single.Phase dimensions with a short.Closed rotor with a capacity of 20 watts are hidden under it. Let me remind you that the rotor is a moving part of the electric motor, which rotates due to. Thereby setting the blade of our fan.

The stator is a static winding that is located on the steel core of the electric motor. The stator transforms alternating current into a rotating magnetic field.

On external examination, of course, it is difficult to break off any device, if there are no obvious signs of damage to the speakers for themselves. In our example, we must call the stator winding and power cord for integrity. This is the easiest to do this using a regular multimeter, which should be in the instrumental arsenal of any radio amateur. About how to use the multimeter, you can find out.

After a series of measurements, it turned out that the supply cord is in perfect order, and the winding of the stator simply burned out at the household fan. With your own hands for repair, we will need to partially disassemble the engine. The stator winding can be easily removed with a regular screwdriver driving it with uniform blows, at the places indicated by the arrows in the photo.

After successful dismantling the stator winding, you can go to mathematics, namely, calculating the number of turns for the engine winding for the engine winding.

For the controlled calculation, you can take the following algorithm as a basis:

The voltage in the normal network of alternating current 220 volts, engine power. 20 watts, core cross section 1.2 cm 2. The current passing through the coil will be. 0.09 A. (based on the well.Known formula I = p/u).

The cross.Section of the typical wire can be calculated according to the following formula :

If we translate the cross.Sectional area of ​​the wire of 0.03 mm 2 to the wire diameter we get as a result: D = 0.19 mm

I borrow the wire from the coil of a magnetic starter with a diameter of 0.17 mm since I don’t know I can lay the right amount of turns on the reel frame.

In the latter case: U. Network voltage, s C is the cross.Section of the core, b C is the magnetic permeability of iron (maximum 14,000 ge).

As soon as we calculate the number of turns, you can start the winding. It is difficult to wrap around so many turns around the core, so I recommend using home.Made.

After the coil is made, it is necessary to soak it with a special varnish for impregnation, otherwise the insulation of the wires in it may be disturbed.

After the varnish dries, it is necessary to install the coil back. If after assembly and verification there are problems with the direction of rotation of the blades, then you only need to remove the rotor and install it from another end core from another end. As an option, you can again pull out the stator coil, and turn it 180 degrees and install it back.

In the figure above the red arrows, short.Closed turns are marked, the magnetic field that affects the rotor will concentrate on them.

In order to find the cause of the fan breakdown, it is necessary, as in the previous example, disassemble it. To do it is pretty simple. First, remove the protective grill, then pull out the blades or impeller, which is usually fixed with a special nut. Then it is necessary to dismantle the other part of the protective grate and unscrew the screws of the lid.

I also recommend that you study the typical scheme of the floor fan. It usually uses an asynchronous electric motor with 8 windings (working and launch). To successfully start the engine, it is necessary to create a phase shift by 90 degrees. For this, the circuit has a capacitor. The scheme will work after pressing the power button, while the indicator lamp should light up and the lobes begin to rotate, the engine rotation speed depends on the connection circuit, using the switch.

First you need to check the serviceability of the network wire. Then perform to launch a motor. It is also recommended to see the integrity of contacts and wires. If a hum or noise is heard during the fan, then you need to grease it with thick lubricant with a lithol.

The repair of the electric motor begins with the lubrication of the bearings, usually after that the fan begins to work well. You can use machine oil for lubrication.

A rather typical malfunction is a break in one of the stator windings. To check, you can sharply twist the blades in the direction of rotation of the clockwise. If the fan works, it has burned one of the windings.

The service life of the electric motor is reduced several times if you do not clean it from dust, and also if you forget to lubricate the bearings or gearboxes.

No matter how well the electrical engineering serves, sooner or later it fails. These devices that are operated very intensively break. They can be considered a household fan to them. Breakage in this product there are various. The owner has no choice but to contact the workshop. However, in some cases, you can do it on your own. To do this, it is quite good to know the device and the principle of operation of this electrical equipment. Information on how to carry out the repair of the fan with your own hands is presented in the article.

## Review: desktop fan Equation Moe 2.

Good day, dear readers of my review!

So the heat imperceptibly came, and such that in our city it reaches 40 degrees. And then the trouble is that in recent years I have become very difficult to endure the heat, apparently, age takes its. Of course, our apartment is ready to accept this, one might say, natural disaster.

We have two split systems in our house, two large fans, which are fully cope with air cooling in our rooms. But we absolutely forgot about the kitchen, but there we also spend a lot of time there.

Unfortunately, our kitchen is small, so for its cooling we decided to purchase a small fan, just nowhere to put. Our choice fell on a desktop fan Equation Moe 2.

What did we like this fan?

It is desktop, has small sizes, which makes it possible to put it in many places of the kitchen. Despite his small size, he copes well with his work.

This fan is very simple in its design, however, it has a “head” automatically turning around and has two blowing speeds. These speeds are switched by a special switch on the back of the fan.

As for the technical part, the fan has an asynchronous electric motor with a short.Closed turn, its design is simple and reliable. Its winding is protected from possible mechanical damage, as well as from dust.

The fan is very compact, its dimensions are: width. 20 cm, height. 27.5 cm, depth. 18 cm, and its weight is only 810 grams. Its power is small, only 15 watts, however, it provides good blowing.

.

My conclusions: We, personally, are very pleased with our purchase. Currently, he is a real worker work in our kitchen, creating us comfortable conditions. Personally, I appreciate him for a simple, but reliable design, a good blowing and a nice appearance (it fit perfectly into the interior of our kitchen). So, if you have a small cuisine, I advise you to take a closer look at this fan. He will provide you with life comfort in this sultry heat.

Of the minuses: several times I had to clean it already. Basically, dust sticks to the fan blades, which adversely affects its performance. But, good, it is very easy to clean it, for this work you do not even need a screwdriver.

## Bringing the household fan to mind for inexpensive.

With the onset of summer, I thought about buying a fan. There was no great need for it, because in severe heat I usually “cut off” the air conditioner, but on a little stuffy days or, rather, the periods of these days, we are quite acceptable to use a banal air. Having estimated what I specifically need it, and, having selyed the market, I found several models that meet my requirements. Since I have no space in the room for installing the flooring, so the fan should have been desktop and always with remote control, because laziness! The price tag of those that I found overcame the threshold of two thousand. Not great money, but for the fan I counted a little much! Over, I did not intend to use it often. Therefore, I decided to wait a bit when the toad is distracted and would not interfere with me to spend money. As it is not rare, everything decided. I walked along Lerua, saw a stand with fans and suddenly bought the cheapest. I could not resist 🙂

The fan is the most common. Two speeds, the possibility of turning when working. But without a remote control! This, of course, is a disaster, but it is not difficult to solve it. To begin with, he opened the case to get acquainted with the Men and understand the general plan of upcoming works.

There was a huge number! It is wonderful! I immediately climbed to visit our Chinese friends for the necessary details. Rather in one. Here:

This is a 220 block of four relay with the possibility of remote switching. The switch is a remote control operating at 433MHz. This remote control is not included in the kit, so the block cost me some kind of penny.He arrived surprisingly quickly, there was also no hint of the heat in St. Petersburg! Mounted it in 10 minutes, neatly and leisurely. Bite off the wires from the buttons and hung them on two relay. And the block itself glued to bilateral tape.

There are really a lot of places inside, the block sat perfectly! And nowhere did it interfere!

After assembly in the reverse order, you could start lying on the bed and enjoy the controlled coolness.For some short time it happened. There was only one minus of all this. This fan blows very strongly and buzzes, even at the smallest speed! It started to annoy me quickly. I had to do something about it. Well, the Chinese helped me again.

The thing is called Dimmer. They can also be controlled by a 220-volt light bulb and not a very powerful engine, such as in a fan.Although there was enough free space in the case, it was convenient to arrange a dimmer, without its improvement, it was impossible. Therefore, I remove an unnecessary bracket and take out a potentiometer on the wires.

## How to assemble a floor fan Tefal

### And you knew that there are fans that also protect from mosquitoes? Tefal with a combined system for supplying fresh air and spraying a product from mosquitoes. My salvation in summer heat

Now I wish you to tell you about the floor fan Essential (Mosquito) Protect VF4210 from Tefal.

The floor fan Tefal VF4210F0 will create a cool breeze and will not let the air stagnate.

### Know Your Electricity Consumption of Pedestal Fan

Three speeds of work will allow you to choose the most comfortable option: from light blowing to a powerful stream (up to 55 cubic meters.M/h). Settings are set by a mechanical swivel regulator.

There is a special slot above the control panel where you can insert any standard bottle of fumigator liquid. Thus, the fan not only refreshes the air, but also sprays the liquid from insects throughout the room.

The fan is packed in a large box of cardboard, which turned out to be quite heavy by weight. You can bring a girl to a girl, but only if carefully.

In fact, there is not very much information, but it is provided in several languages ​​at once.

It seemed to me not very convenient that the box is not equipped with any handle.

Inside everything was composed very tightly, so even when turning the box. Did not shake and did not thunder.

### Review of the floor fan Tefal VF4210F0

The fan is sold in a disassembled form, so you will have to collect it yourself. Each element is neatly packed in protective material, only the blades were without everything.

The first, and probably the most difficult part. Foot stand.

She was packed in a plastic bag.

Inside which there were additional details for assembly. I liked that all sorts of screws and screws immediately went at the same time with those details where they had to be screwed.

The stand weighs decently, thanks to this the fan is stable even at maximum speed.

At first I did not quite understand why the stand is so dirty. But wiping it with a rag, she found that it was a plastic of such an interesting color in itself.

Outwardly the stand is made of white plastic. External rim. Glossy, and inner circle. Matte.

Next comes the leg. She is firmly packed in cardboard.

And also in film, so that nothing gets scratched.

It is not very heavy, although it is made of metal. Visually, it is glossy and smooth. It is sold short, but its length can be adjusted at your discretion. The maximum fan height. 140 cm.

The next is the basis, which, like all other details, is carefully packed in protective material.

Probably, it is stronger than all, since he was at first in cardboard and foam, and then. In the package.

The cord is also wrapped in a film, and inside is still tumored with wire. Its length. 1.5 meters.

The basis, from which, in principle, the fan works is also quite weighty.

Looks like a device for checking the speed of machines.

A head of glossy black plastic is strung on the base.

Behind there is a small sticker with the power of the device and the brand logo.

On the basis there is a compartment, thanks to which this fan model and differs from all others. Antimoscate function.

The cover is very tight, I almost broke a couple of nails for myself until I opened it for the first time. Then I realized that it was better to use fingertips.

You can screw any liquid from insects into the compartment, and click on the button with the inscription Protect when operating the fan, and the air flow will begin to spread the liquid throughout the room.

They are not very wide, which allows them to spin easily and quickly.

Details of the body protecting the screw were in the same packaging.

There was some incomprehensible and unnecessary piece of paper inside.

The case consists of 2 parts of the same shape. They lie in each other, and there are a couple of paper sheets between them.

The upper half has a logo located on a plastic circle, as well as an external rim.

The back panel is completely metal.

When assembly, the base is quite voluminous.

Air easily passes through a small mesh, but it also protects well from a spinning screw.

As I wrote earlier, the fan is sold in a disassembled state. The assembly is basically easy, it will not take much time if you first study the instructions. I managed in 20 minutes.

The instructions have options for assemblies of several models at once, so look for yours by number. My one that is presented on the left side.

First you need to assemble the lower part of the fan.

Next comes the upper part with a spinning mechanism.

It must be placed in an open part of the stand.

Previously, it is necessary to unscrew the screw inside, otherwise the stick itself will not stand tight and will fly out.

It is removed using a special mechanism.

If desired, you can immediately adjust the height of the finished fan.

From the base, twisting the screws, you will need to unscrew a couple of details.

It is easy to do this, since there are instructions on which direction you need to turn.

They are unscrewed quickly and without problems.

### Goodmans 16″ Oscillating Pedestal Fan Assembly

No keys and screwdrivers, everything is done with your hands.

### TEFAL Essential fan []

The pin on which it is necessary to string parts of the base and blades appears to us.

Then it is twisted by a little thing, which we unscrewed the second. Make sure that everything is tightly screwed and does not hang out, since you do not want a part of the fan with working blades, God forbid?!

## Overview for Fan Faller Zanussi ZFF-705

We consulted with colleagues and decided to buy a fan to the office, the choice is huge in the market, but I did not want to take it very cheap.

Chose relatively non.Expensive, within 2 thousand, so that there was a powerful enough (

45 watts or more), not very low (almost all a meter in height), the stand would be round and not in the form of a cross, since on a cross for such money they cost very uncertainly, well, so that it looks worthy.

I chose as always on online.Ru, never let me down!

Of the suitable ones, several Ballu and Zanussi were suitable for our criteria, but the former had some kind of problem with the presence, so it was decided to take Zanussi ZFF-705, there were no reviews of it, they took at their own peril and risk.

The order came the next day, as always thanks online.Ru for operational delivery and that they did not allow to die from the heat.

Came disassembled, in a dense cardboard cow, beautifully decorated.

For assembly you only need a thicket of a protective grid to tighten.

It looks very bad. The stand is heavy, it stands confident on it, the right choice.

The power is an excellent fan, at 3 speeds blowing off in the office everything that is poorly held on tables and walls (documents, calendars).

The noise is quite quiet, only the wind is heard.

The buttons are decent, require confident pressing with pressing until the end.

The height is adjustable using a special steeple.

There is one claim to painting a protective grid.

In one place was painted as if on a piece of whitewashing or other powder.Like and when assembly, the paint took off safely.

I took a picture after tinted with a black marker, now it is not striking. Not critical.

The fan can be adjusted up and the rotary mechanism works, below the video example of work

As a result, I can recommend this fan for buying, he fully justified my requirements and expectations.

## Review: floor fan Zanussi ZFF-907-without a fan at home in the summer.

I want to share with you my impressions of the Fleet Fan Zanussi ZFF-907, which we recently purchased on our favorite “berry” site when our good old one, who has been serving for almost 9 years, just scattered into pieces. Therefore, they urgently began to look for something budget-not to die in the heat of the house (we also have the sunny side).

Here, on an echo, I did not find reviews, and those that are written on the site itself. The frightening ones were interspersed with the enthusiastic. I decided to tell in order about our purchase exactly here. So that it was clear before placing an order that you are buying.We paid 1899 for the fan (ordinary. Specially compared in ordinary city stores).He came in such a box.

The main information about the product is provided on the box.

In fact, what you need to know before buying: the fan has no legs, instead of it a round (rather heavy) base, mechanical control. 4 buttons: three speeds and a shutdown button, its weight is 4.5 kg and it is quite bad in operation. This is in short.In this form there was a fan inside the box. Since it is new, of course, disassembled.

Here is such a base, we took off the film, it shone directly. Only now the dust is easily sitting on him.

Blades and protective grilles were in a separate package. Everything came whole and unharmed.

And of course, the instructions for use was inside the box.

My husband and I were struck by the blades-firstly, they are transparent.

Secondly, for some reason a feeling of fragility is created-but perhaps this is precisely due to transparent material.

This is what it looks in the collected form. Very stylish, in my opinion, is suitable for any interior.

This is what the control panel looks like. Ordinary buttons, but you can quite quietly switch them. Tried already while the children were sleeping, and it was necessary to put the first at the first at night. Quite convenient.

The protective grill is quite small, which is convenient in a house with young children. It is more difficult to put your fingers there. Not that impossible, but still.

As for the work. Here we were satisfied. The fan is powerful, the air distiliates well. At the third speed, of course, it works noisily, in the sense that it is heard, but this is such a pleasant rustling. Yes, and we usually put on the second speed, and at night we switch to the first. This is quite enough. At the first speed, the fan works almost silently, almost like a light breath of wind.

Exhaust fan. A device that can more often be seen in the houses of our fellow citizens. There are several reasons for this. Firstly, recently, thanks to a significant reduction in the cost of the production of such devices, almost everyone can afford such a purchase. Secondly, this electrical appliance is certainly a very useful purchase for an apartment and a private house.

### The electrical circuit of the household fan and its features

The main task of the exhaust fan is to ensure forced artificial air circulation in those rooms where natural circulation is difficult or not enough. A vivid example of such a room is the bathroom. In apartment buildings, as a rule, this room is far from external load.Bearing walls, and, therefore, air circulation in them is difficult. If you add increased humidity and mold arising from it, it immediately becomes clear that the exhaust fan to the bathroom is not just a tribute to fashion, but a real need.

In order to connect the fan, you need to know a few small nuances. You need to understand that the electrical circuit of the fan connection is largely determined by the place of its installation and the presence of its features in the design.

Connection with a built.In switch. The simplest scheme. The device is brought to the device in 220 in. Turning on and turning off the fan occurs due to a built.In circuit breaker.

Connection via the switch. By applying this circuit, the fan is turned on and off using a special switch. As a rule, it is located in front of the entrance to the room. For such a connection, it is necessary to lay 2 cables. One from the camshaft to the switch, the second. To the device itself.

Connecting a fan with a timer. The peculiarity of these devices is that they do not turn off immediately, but after a certain time. This is carried out due to a special time relay that automatically shut off the device after a pre.Set period of time (usually from one minute to half an hour). With this connection, one wire goes to the switch, and two to the device.

Connection of the fan to the humidity sensor. The electrical circuit of control of the fan may include the presence of a humidity sensor that measures the readings in real time and, consistent with the given program, monitors the operation of the device. It includes it with a humidity and turns it off at the moment when it reaches the optimal values. The connection diagram of the device is similar to the one that is necessary to connect the fan with the timer.

Most fans consists of switching circuits, launch, wraps of an electric motor. The list of elements concerns the repair. Often in household models, a trivial coil is used, wound up copper residential with lacquer insulation. Let us consider today how to repair the fans with your own hands, the inductance has burned down, the wire was torn due to the improving of the operator. To restore the coil, a good old device is used, despite simplicity, you can’t get it in the store. With the help of the mechanism, they wind the inductance using an electric drive, working with handles.

Industrial fans have otherwise, unlike household, more often centrifugal. The winding of the collector, asynchronous engine at home cannot be restored, it will be difficult to do it. Craftsmen repeat the production cycle in their native penalties.

## Checking the fan electric motor

Let us consider in detail. How the fan motor is being checked. An example is an electric motor corresponding to the version of household desktop fans.

The photograph shows a small electric motor \ photo \ desktop fan. To state this topic more understandably, the clarification will be accompanied by personal photographs. For the diagnosis of the electric motor.

Diagnosis of electrical connections begins with a preliminary check directly by the device itself \ photo \.

Why is such a check is needed?. The verification is carried out to be convinced that the wires of the probe of the device do not have a gap. That is, in practice, such a malfunction of the device as a wire break in conjunction with the probe \ Metal pin in conjunction with the wire \ is often found.

With a break, \ for a certain section of the electrical circuit \ display of the device multimeter. Shows »Unit”. If the two probes of the device are closed together at the same time \ with the displayed range of the lowest resistance \, the device display will show the zero resistance value. For this example, this will mean that the device acting \ serviceable \.

## Installation according to all the rules of the duct fans

The installation rules of the duct fans directly depend on the design of the device, type and cross.Section of the duct, the purpose of the premises where the installation is carried out. In domestic conditions, the possibility of using the duct fans is limited, basically, they are used in not very large rooms. In order to choose the right device for the right performance, you need to find out the need for the room in the tributary or exhaust of the air.

The necessary data can be found in SNiP, or just find on the Internet. It is also necessary to think in advance in advance the possibility of accessing the fan for maintenance, repair or replacement. The need for such actions can occur at any time, and the device must be placed at easily accessible points with the possibility of approach. In addition, it is necessary to securely fix the fan on the supporting structure, wall or ceiling so that it does not rely only on the duct. Otherwise, a tangible rumble will appear when working, the load on the air ducts can disable them.

### What you need for installation

The task of installing the canal fan is to join it to the network of air ducts with sufficient quality and density of the connection, as well as to connect the power supply. To perform these works, a set of certain tools, wires and fasteners will be required. Depending on the type of installation, it may be required:

• Kryazuvka for metal or wood with a small tooth (for cutting the canal)
• Peorator
• Electrodegol with a set of drills
• Dowels and screws
• Electric wire
• Terminal pads for connecting a fan

In some cases, other tools or materials may be in demand, since installation conditions, quality and material of air ducts and the type of fan can be completely different.

### Work quality requirements

The work performed should provide a dense, silent and motionless connection of the fan to the air channel

When working, there should be silence, there should be no holes or non.Failure of the connection. It is also necessary to ensure a low level of vibration in order to exclude the possibility of weakening compounds, the appearance of unpleasant sounds or impaired compound tightness. The connected device should be launched from a separate switch, or simultaneously with lighting devices, which is convenient for bathrooms.
