When choosing an automatic washing machine – the first in your life or to replace the old one – you might have heard about inverter washing machines. How do they differ from ordinary ones, and why is so little known about them in the circles of potential buyers?
We will give you answers to these and other questions in this article.
Inverter motor – a successful development
The efforts of engineers led to the fact that, among others, an inverter motor was invented in a washing machine. Thanks to its appearance, the new generation of machines surpassed all previous models in terms of energy efficiency by as much as 20%.
In addition, another “bonus” has appeared – automatic shutdown, which helps to save on electricity bills.
Features of inverter motors:
- The induction motor is not equipped with brushes, which means that they will not wear out. Nothing will have to be changed, as in collector and brushless motors.
- A machine with such an engine spins at a speed of 1600 revolutions in 1 minute – the laundry at the exit from the drum is almost dry.
- Washing machines with an inverter motor, again due to the lack of brushes, have become famous for being silent. Depending on the selected mode – “Washing” or “Spin” – the noise level ranges from 53-76 dB.
Inverter motor saves water
Thanks to the modified design and the slight tilt of the drum, you can save a lot of water. Maybe for someone 10% will not be an impressive figure, but for users who actively use the machine, this will be a strong argument.
The drum of the machine with an inverter type of motor also allows you to conveniently load and unload laundry.
Increases washing efficiency
“Faster, higher, stronger” – this almost Olympic principle is realized through the Beat Wash system, which implies the presence of a 3D sensor. It is he who increases the efficiency of washing.
The system is able to make adjustments to the trajectory of moving things along the drum in order to achieve the perfect balance of the laundry. All this provides the so-called “three-dimensional” washing.
Benefits of 3D system:
- Washing becomes delicate: the linen does not wrinkle and does not curl at random.
- The system adapts to the washing and characteristics of different types of fabric.
- Beat Wash may reduce the time required for a cycle depending on the type of laundry loaded.
All about inverter motor
Consider what an inverter motor is in a washing machine. The principle of operation of such an engine lies in the fact that a frequency converter is responsible for its revolutions, more simply – an inverter.
Its task is to convert alternating current to direct current, and then to form an alternating current of the required frequency. The good thing about the process is that the engine speed is controlled with high precision to maintain the required frequency.
The main feature that distinguishes an inverter motor from any other is the absence of brushes. The rotor of the engine, as in all others, rotates according to a single principle – under the influence of an electromagnetic field.
Pros:
- High coefficient of performance (COP).
- Durability (no replacement parts).
- Precise maintenance of the required speed and instant access to the desired number.
Inverter machine: pros and cons
Having understood the principle of the operation of an inverter motor, one may wonder – is this really a useful technology in a washing machine, or just another publicity stunt for PR people? Nobody wants to overpay for non-existent benefits, so we will figure out what is true and what is not.
Myths and Reality
- Energy efficiency. True, and above we explained why.
- Quieter operation. Proven and verified.
- Spin at high speed. You yourself will feel that this is the case when you take out almost dry laundry from the drum.
- Durability. The motor – yes, is durable, but the inverter principle does not affect other parts of the machine. If bearings leak in it or the heating element burns out, no engine will save from repair.
- The number of revolutions is observed with mathematical precision. Also repeatedly confirmed by experts.
- Affordable price. No – the cost of such a washing machine sometimes “bites”.
- Affordable motor repair. This is unlikely: in view of their novelty, it is expensive to repair inverter-type motors – consumables can cost decently.
We do not undertake to judge which type of engine is better in a washing machine. Having collected all the facts given in this article, you yourself can draw conclusions whether it is worth taking a newfangled washing machine.
If you are going to turn on the CMA frequently, want to save on electricity and not flinch from noise, then this is undoubtedly your option. And if the budget is limited, then you can not overpay – the decision is yours.
