When buying a washing machine, we pay attention to the type of loading, the washing class, the capacity and the material of the drum. But do not forget about such an important element as the engine. The main parameter that should excite you is the power of the engine of the washing machine.
Why and why you need to know this characteristic when buying SMA, we will tell in this article.
Types of engines in washing machines
Engineers in the history of the development of washing machines have settled on three types of engines, which are used to date:
- asynchronous;
- collector;
- brushless.
Asynchronous motors
The motor for an asynchronous washing machine can have both a two-phase and a three-phase design. In modern models that came off the assembly line after 2000, they refused to use two-phase motors.
The motor power of an asynchronous type in automatic machines usually ranges from 180 to 360 watts, and the number of revolutions per minute during spinning is about 2800. During washing, the speed of such an engine reaches 300.
As a result, spinning parameters in machines with asynchronous motors rarely exceed the 400-600 rpm mark (extremely rarely reach 1000).
Collector motors
This type of motors replaced the asynchronous one. Their work can be provided by both variable and direct current. Their dimensions are more modest, and there is additionally provided for smooth regulation of the revolutions using the command unit.
There is also a significant drawback - in such motors there are brushes. Over time, they are erased, and require replacement.
The power ranges from 380 to 800 watts.
Important! The power consumption of the engine during washing and spinning can be significantly different. This indicator can not be found in the user's manual - the manufacturer writes about this at the very details.
Brushless motors
This is the latest type of engine, which has been used in the design of AGR only since 2005. The discoverer was the LG brand.
The main feature, which distinguishes the engine from all others, is its direct connection to the drum. Such machines are characterized as SM with a direct drive, and they do not have a drive belt. The engine itself is compact, its design is as simple as possible, and the efficiency is high.
Power is not inferior to the details described above, and the number of drum revolutions per minute during spinning can be 1600, and even 2000.
Power and power consumption
The power level of the entire machine depends directly on how much power the electric motor has for the washing machine. It is this parameter that affects how many kilowatts per hour your washing machine "winds". When choosing the stylalki just this, rather than the power of the engine excites the buyer.
In general, the energy consumption is affected by a number of factors:
- Engine power.
- Heater power. On average, the heater can consume from, to, kilowatt. At high temperatures, the power increases.
- Capacity of the drain pump. It ranges from 24 to 40 watts. This figure is enough to pump the waste water out of the tank.
- Total power of sensors, control and display unit. Within 5-10 watts.
The overall indicator for the whole CM is calculated only for one mode - "Cotton with heating to 60 degrees and with a full load of the drum.
According to the received indicators, the machine is assigned a class of energy efficiency. Classes are denoted by Latin letters from G to A, where G is the lowest class, and A is the most effective.
Important! The number of revolutions of the drum during the "spin" mode directly depends on the motor power.
So, the higher the power of the engine, the more revolutions the drum can make when spinning. These figures were also calculated by the manufacturers, which affected the spinning classes.
So, the spinach pressing at a speed of 1600 rpm is class A. But for full-value spinning, even 800 revolutions will be enough. And if you are going to often wash delicate fabrics, then the number of turns you generally should not particularly worry - the less, the better: things will be intact.
Conclusions about engine power
How do you know how many turns the electric motor of the washing machine has? How to determine the power of the motor? How on the basis of this not to make a mistake in the choice of technology?
It's simple: the stylalki made after 2000 are delivered to stores already with collector or brushless motors. Their power may differ, but this is not the most important indicator for the consumer, since the most important issue is the optimal energy efficiency class.
Therefore, if you do not want to understand the technical nuances of motors, just choose a car of class A or A +.
