Inverter motor in a washing machine: what is it? Pros and cons

Most people who watch ads know that the best and most reliable washing machine is the one that contains an inverter motor. What kind of engine is this and how does it differ from standard motors? In our article, we will analyze this detail and some models of washing machines that carry such an engine.

What is an inverter motor, its type and advantages

From one name it becomes clear that the basis of this motor is the speed control by an inverter or frequency converter, which generates alternating current of the frequency that you need. In this case, the rotation speed and the desired speed are kept at the level called for.

Advantages of an inverter motor

Based on the basic characteristics of a washing machine with such an engine, we highlight the following advantages:

• Saving electricity and increased efficiency is due to the fact that in the washing machine there are no parts or brushes rubbing against each other, which means that less energy is consumed to rotate the rotor;
• In the process of use, you do not have to change parts that are not there initially;
• The motor is low frequency, which makes it with reduced noise level;
• The user himself can choose the number of revolutions, which makes it possible to maintain a cycle washing process.

Advantages and disadvantages: which of these is more important

As soon as we figured out the principle of operation of this unique engine and the design as a whole, it is worth considering how useful and necessary this engine is for a washing unit. What are the advantages and what do they give the design? Is it worth overpaying for a washing machine with an inverter motor, or should you keep a drum type with electric brushes? Consider the advantages of this engine:

• Efficiency through energy;
• Reduced hum level (noise);
• There is the possibility of spinning at maximum speed;
• Long term use;
• Accurate correspondence of the value of revolutions during the washing process.

There are also disadvantages:

• Pretty high price;
• A rather expensive repair can come out if the structure breaks down, since the parts are expensive.

More about basic characteristics

As soon as we have considered and learned for ourselves all the characteristics, it is possible to examine them closely. The main and main advantage is energy efficiency.

The energy use of inverter washing machines is twenty percent lower than conventional drum washing machines.

The statement about the lowest noise level among all is rather controversial, because conventional collector structures are a bit quieter. However, if we take a direct drive washing machine, then the hum level will become much less. Washing units with direct drive are designs where the drum is not present belt.

The issue of spinning at maximum speed is also quite controversial, although the laundry in this case will come out quite dry. There is a chance that if you set the rpm value to 1600 or much more, for example, to 2000 rpm, then the things from the drum will not be completely dry, but rather torn to shreds. Even if your things come out quite intact, then it makes no sense to talk about their life expectancy.

The fact about the durability of the inverter motor brightens up the shortcomings quite well, although conventional washing machines serve the owners from fifteen to twenty-five years. And even if your design lasts you much longer, you will still want to change your washing machine to a newer model. A durable engine, is it even necessary?

Another advantage is the ability to accurately know the number of revolutions of a given type of engine. Do you need this value and what is it in general?

Buying a washing unit: choice

We examined the advantages of an inverter motor in a washing machine, and we already know and understand what it is. It remains to make a choice based on the conclusions whether you need a unit with such an engine or leave the usual, drum one.

You must understand that this engine is not a complete plus that other conventional washing machines can cover. Of course, the fact that electricity is consumed much less than conventional washing machines, which makes it possible to save money, pleases the inhabitants of a country with incredibly high utility rates.Plus, there are no electric brushes, but is this plus worth overpaying for it?

Energy classes for washing machines

If energy saving is very important for you, then you should look not at the presence / absence of inverter technologies, but at the energy consumption class. Energy classes are marked in English letters in their alphabet, the first in alphabetical order (with two pluses “A ++” assigned) is the value of the most energy-efficient washing machine. Class G does the opposite, and uses a huge amount of electricity.

Let's show how it is measured, for example:
A++ uses up to 0.15 kW/wash cycle;
G uses from 0.39 kW/wash cycle.

Not only the class affects the use of electricity, but also the following values:

• Selected temperature and combination of washing programs - the higher the temperature and length of the program, the more electricity you will need;
• The amount of laundry placed inside also affects the energy consumption;
• The type of material matters, because dry or wet linen, or rather their weight, differ;
• Usage time: The more time you spend on your washing machine, the more energy it needs.

Washing designs with an inverter type motor from Samsung

Model Crystal standard. There is an Eco Bubble system (bubble wash technology), which is able to wash soiled items even at a temperature of fifteen degrees.

A fairly gentle wash, and stains can be removed in both warm / hot and cold water.

There is a special mode for washing in cold water.

Model Yukon. The body is painted red, which adds a touch of elegance.

This washing machine has a dry washing system, linen with soiled areas gets off with hot air currents, which makes it possible to get rid of various kinds of odors and microorganisms.

Suits and things made of wool fit well enough for such a washing system. There is an Eco Bubble system.

LG Inverter Washing Machines

LG also produces models with this engine.

Model 6 Motion. The technology is that the drum spins in different directions, and not, as usual, only in one direction. There are 6 such functions in this washing machine:

1. To detergents quickly dissolved in its process, reverse movement is used;
2. Soaking laundry is efficient thanks to the rocking function;
3. Saturation fairly evenly separates the laundry detergents (powder, fabric softener);
4. The twist function allows you to scroll the laundry inside the surface with bubbles;
5. The smoothing function will help you to conveniently smooth out the wrinkles on the washed laundry without any difficulty;
6. Standard rotation function.

There is also a steam washing system, as well as the aforementioned inverter motor, the technology of operation and structure of which you have already learned from our article.

This engine has a direct drive, which has proven to many buyers the effectiveness of its work.

conclusions

We can conclude that before you buy a washing machine with an inverter motor, you should pay attention to the additional features and read the reviews of users who have purchased such a washing machine.

There are a lot of comments on the Internet about washing machines with this engine (mostly reviews go to manufacturers LG and Samsung). The attention of consumers is aimed not only at the presence of a powerful engine in the washing machine, but also at the presence of a direct drive and various other programs.
