What does an inverter motor in a washing machine mean

Inverter machine: pros and cons

Having understood the principle of the inverter motor, you can wonder if it is really a useful technology in the washing machine, or just another promotional move of PR men? No one wants to overpay for non-existent benefits, so we will sort out what is true and what is not.

Myths and reality

  • Energy Efficiency. True, and above we explained why.
  • Quieter operation. Proven and proven.
  • Spinning at high speed. You will feel it yourself, taking almost dry laundry out of the drum.
  • Longevity. The motor. yes, it is durable, but other parts of the machine are not affected by the inverter principle. if the bearings leak or the heating element burns out, no motor will save you from the repair.
  • The speed is observed with mathematical precision. Also repeatedly confirmed by experts.
  • Reasonable price. No. the cost of such a washing machine sometimes “bite”.
  • Affordable electric motor repair. This is unlikely: due to their novelty, inverter-type motors are expensive to repair. consumable parts can cost a pretty penny.

We do not judge what type of motor is better in a washing machine. Collecting all the facts given in this article, you can draw your own conclusions, whether it is worth to take a new-fangled washing machine.

If you are going to switch on the washing machine often, want to save on electricity and not shudder at the noise, then, undoubtedly, this is your option. And if you’re on a tight budget, you don’t have to overpay.

This compact model has a front loading of laundry and has a considerable capacity of drum up to 6kg. The machine is equipped with an impressive functionality and automatic control. The model has 13 special and standard washing modes: synthetics, cotton items, wool and other fabrics.

There are two accelerated modes and a rinse and spin. The drum has several options of rotation for washing in various programs.

When spinning, the drum spins up to speed of 1000 rpm, reaching at the end of it to achieve a humidity of 45. 54%.

It is possible to postpone the start from 3 to 19 hours, allowing the machine to start at a convenient time. Equipped with mobile diagnostics of failures and errors it is possible to determine the possible failure remotely. By phone the expert will decode the sound combination coded by the machine.

LG F-1296 ND3

The main feature is the ability to recognize the type of laundry, thanks to which the model selects and adjusts automatically the best program for washing. But if you want you can change the settings to other, reducing or increasing the spin, changing the water temperature when washing.

The control panel is lockable if desired to prevent accidental button presses. Washing machines of this model are equipped with a direct inverter motor with a noise level not exceeding 74 dB.

The benefits of an inverter motor

Inverter washing machines can boast:

  • Lower power consumption and better efficiency (this occurs due to the fact that in the design the number of moving parts has been reduced);
  • high durability (you do not have to change the brushes of the engine from time to time);
  • Low noise level (achieved, again, by eliminating the rubbing parts);
  • reduced vibrations during the washing process, which contributes to a better distribution of laundry in the drum;
  • instant access to the desired speed and its support;
  • Smoother start, which is less wear and tear on the engine;
  • spinning at high speed;
  • dry laundry in the output due to the high number of rotations per minute (up to 2000).

Most models with ID are frontal, but there are also vertical versions, such as Gorenje WT 62113. It costs about 20,000 and is designed to wash 6 kg.

The inverter motor is a stroke of genius

Efforts of engineers have led to the fact that, among other things, was invented inverter motor in the washing machine. Thanks to its appearance, the new generation of machines surpassed all previous models in energy efficiency by as much as 20%.

In addition, there is one more “bonus”. automatic shutdown, which helps to save on electricity bills.

  • The induction motor has no brushes. so they won’t wear out. No need to change anything as with collector or commutatorless motors.
  • The machine with such an engine spins at speed of 1600 rpm for 1 minute. the laundry is almost dry when leaving the drum.
  • Washing machines with inverter motor, again, thanks to the absence of brushes, are renowned as silent. Depending on the selected wash or spin cycle, the noise level ranges from 53-76 dB.

Inverter motor saves water

Thanks to a modified design and a slight inclination of the drum, you can significantly save water. Maybe for some people 10% will not be an impressive figure, but for users who actively use the machine, it will be a strong argument.

The inverter drum also makes loading and unloading convenient.

Improves washing efficiency

“Faster, higher, stronger”. this practically Olympic principle is realized by the Beat Wash system, which implies a 3D-sensor. It’s the one that makes washing more efficient.

The system knows how to make adjustments to the trajectory of the items on the drum in order to achieve a perfect balance of laundry. All this provides the so-called “three-dimensional” washing.

  • Washing becomes gentle: the laundry is not crumpled or twisted as if by mistake.
  • The system adapts to the washing and peculiarities of different types of fabric.
  • Beat Wash can reduce the time required for a cycle, depending on the type of laundry loaded.

All about the inverter motor

Consider what an inverter motor is in a washing machine. The principle of operation of such a motor lies in the fact that a frequency converter, more simply. an inverter, is responsible for its speed.

Hisense WM Inverter motor HQ, 3D animation

Its task is to convert AC power into DC power, and then to generate the AC power of the desired frequency. The process is good in that the speed of the engine speed is regulated with high precision to maintain the required frequency.

The main feature that distinguishes an inverter motor from any other motor is the absence of brushes. The rotor of the motor, as in all others, rotates according to a single principle. under the influence of the electromagnetic field.

  • High efficiency.
  • Durability (no replaceable parts).
  • Precise maintenance of the required speed and instantaneous output.

Inverter drive in a washing machine: what is it

When selecting a machine for washing, you still need to look at the type of drive. Recall, it can be of the belt type or direct inverter type. The latest version is more modern. Connecting the drum and the engine has led to an improvement in the washing machine, as the entire system has gained dynamic equilibrium. It was given the name Direct Drive or inverter motor with direct drive.

There are quite a few devices with such a drive on sale. Predominantly they are all from the company LG. And Samsung has released several devices. There are similar appliances from one to two other manufacturers and that’s it. Due to the fact that the direct drive has been introduced in household washing machines, the control of the pace, direction of rotation and accuracy of drum movement has been improved.

Reference! Clamping the motor and the drum of the appliance on a common axis allows to reduce noise and vibration. And with the direct drive, the mechanical load and wear and tear on the individual links is significantly reduced.

Inverter motor in a washing machine: what is it

To understand what is an inverter motor in a modern washing machine, it is necessary to understand the features of its device and present the principle of operation.

Design Features

The main element indicating that it is an inverter motor in the washing machine in question is the inverter. This electronic converter is capable first of changing the incoming alternating current with the standard characteristics of 220 V and 50 Hz into direct current, and then to generate alternating current again, but already with a given frequency. Smooth regulation of this parameter is capable to set rotor speed with high accuracy, and with it. and drum of the machine.

The presence of such an intelligent unit made the electrical design of the product more complex and increased the price of the product somewhat. But the user receives a lot of advantages that are discovered during the operation of the unit.

The inverter motor contains no brushes and operates with a reduced noise level. It has a more compact design and can be located on the same axis with the drum. No belt drive reduces wear on moving parts and extends the life of the machine.

Operating Principle

The principle of operation of the inverter motor in a household washing machine is based, as with electric motors of other designs, on the use of electromagnetic induction. But there is an essential difference. Instead of graphite brushes, the role of controlling the winding currents has taken over the inverter.

As a result the rotating rotor is less inertial and is easier to achieve the desired speed. There are no rubbing parts inside this device, which leads to reduction of unwanted heating and irrational waste of energy. Such a motor reliably works at the highest speeds.

Special Note! Modern inverter motor often has the form of a disk with a shaft located on its central axis.

Advantages and disadvantages

To assess what an inverter motor in a washing machine means for the housewife, it is enough to list its strengths and weaknesses.

  • An advanced control system ensures higher efficiency, which leads to a 20% reduction in running energy costs, according to experts.
  • No moving parts, less wear and tear, easier maintenance and longer unit life.
  • Reduced noise level does not inconvenience users. This is especially important for families with small children and sick people.
  • Surprised by the high spin speed, many of us do not realize that this inverter motor in a modern washing machine allows you to speed up the drum to 1600 or more revolutions per minute.
  • The inverter provides exceptional speed control precision.
  • The small dimensions of the motor enable it to be mounted on the same shaft with the drum, resulting in a more compact machine and easier balancing of the loaded drum.
  • The cost of inverter machines is usually higher than conventional units.
  • Repair work, especially replacing the inverter, will cost the owner a pretty penny.
