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

Most people who watch commercials know that the best and most reliable washing machine is the one that holds an inverter motor. So what is this motor and what makes it stand out from standard motors? In our article, we will break down this detail and some models of machines that carry such a motor.

What is an inverter motor, its type and advantages

The name alone makes it clear that this motor is based on speed control by an inverter or frequency converter, which generates the alternating current of the frequency you need. In this case, the rotational speed and the desired speed are kept at the level you call for.

Advantages of the inverter motor

Based on the basic characteristics of a washing machine with such a motor, we distinguish the following advantages:

• Electricity savings and increased efficiency is formed due to the fact that in the machine there are no rubbing parts or brushes against each other, which means that less energy is spent on the rotation of the rotor;
• In the process of use, you do not have to change parts that are not there to begin with;
• The motor is low-frequency, which makes it with a reduced noise level;
• The user can select the number of revolutions, which makes it possible to maintain the cycle the washing process.

Advantages and disadvantages: which is more important

Once we have understood the principle of operation of this unique motor and the design in general, it is worth reflecting on how useful and necessary this motor is for the washing machine. What are the advantages and what do they give to the design? Is it worth overpaying for a washing machine with an inverter motor or keep the drum type with electric brushes? Let's consider the pros of this motor:

• Energy efficiency;
• Reduced hum (noise);
• There is the possibility of spinning at maximum speed;
• Long service life;
• The accurate correspondence of the rotation speed during the washing process.

There are also disadvantages:

• Rather high price;
• It can be quite expensive to repair, if the construction breaks, as the parts are expensive.

More details about the basic characteristics

Once we have considered and learned for ourselves all the characteristics, there is an opportunity to consider them up close. The main and main advantage is the energy efficiency.

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

The claim of the lowest noise level of all is quite debatable, because conventional collector designs are a bit quieter. However, if we take a direct-drive washing machine, the hum level is much lower. Direct-drive washing machines are designs where the drum does not have a belt.

Quite controversial is the issue of spinning at maximum speed, although the laundry in such a case will come out quite dry. There is a chance that if you set the rpm to 1600 or much higher, for example 2000 rpm, the items will not be completely dry from the drum, but rather torn to shreds. Even if your items come out fairly intact, there is no point in talking about their longevity.

The fact about the longevity of the inverter motor pretty well ameliorates the disadvantages, although conventional washing machines last from fifteen to twenty-five years for their owners. And even if your design lasts much longer, you will still want to change your machine to a newer model. Longevity engine, is it even necessary?

Another benefit, is the ability to know the exact RPM of a given type of engine. Do you need this value and what is it anyway?

Buying a washing machine: the choice

We have considered 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 a motor or leave the usual, drum one.

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

Energy Classes of Washing Machines

If energy saving is a very big value for you, you should not look at the presence/absence of inverter technology, but at the class of energy consumption. Energy consumption classes are marked with English letters in their alphabet, the first in the alphabet (with two "A++" pluses attached) is the value about the most energy efficient machine. Class G acts 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/cycle of laundry;
G uses from 0.39 kW/cycle of laundry.

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

• The selected temperature and combination of washing programs - the higher the temperature and program length, the more electricity you'll need;
• The amount of laundry placed inside also affects the power consumption;
• The type of material matters, because dry or wet laundry, or rather their weight is different;
• The time of use: the more time you spend working with the washing machine, the more energy it needs.

Washing designs with an inverter motor from the company "Samsung"

Model Crystal Standard. There is an Eco Bubble system (bubble washing technology), which is able to wash dirty things even at a temperature of fifteen degrees.

It is neat enough to wash, and stains can be removed in both warm/hot water 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 machine has a dry washing system, the laundry with dirty areas is finished with streams of hot air, which makes it possible to get rid of various kinds of odors and microorganisms.

Suits and woolen clothes will fit well enough for this washing system. The Eco Bubble system is present.

LG inverter washing machines

LG also produces models with such a motor.

The model 6 Motion. The technology is that the drum rotates in different directions, not as usual only in one. There are 6 such functions in this machine:

1. In order to laundry detergents quickly dissolve in its process, it uses reversing motion;
2. Soaking the laundry is effective thanks to the rocking function;
3. Saturation rather evenly separates the washing products (powder, fabric conditioner);
4. Torsion function allows you to scroll the laundry inside the surface with bubbles;
5. The smoothing function helps you conveniently smooth out creases on washed laundry without any difficulty;
6. Standard spin function.

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

This motor has a direct drive, which has proved to many customers 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 additional features and read the reviews of users who have purchased such a machine.

There are a large number of comments on the Internet about machines with this motor (mainly the reviews go to the manufacturer companies LG and Samsung). The attention of consumers is aimed not only at the presence of a powerful motor in machines, but also the presence of direct drive and other all kinds of programs.
