What is the heart of the washing machine, it must be the Washer Motor

What is the heart of the washing machine, it must be the Washer Motor . It is the washer motor that can bring strong power to the washing machine. So how do we choose a wide variety of motors on the market? Next, I will explain several common washer motors on the market.

Let us first take a look at the washer motor used in the fixed frequency washing machine. When we buy a washing machine, we often hear ordinary motors, but what about ordinary motors? In fact, ordinary motors are just a big classification, including induction motors and series motors. The induction motor is a common single-phase motor with internal capacitance.

When such a motor is applied to a washing machine, the number of turns of the primary and secondary windings is the same, and the steering can be completed only by changing the position.

The motor has the characteristics of simple structure, high efficiency and convenient use. However, due to the inability to adjust the speed, the starting performance is poor, and it is mostly applied to the washing machine. By changing the windings, the induction motor can also change different speeds. Such "two-speed" motors are more commonly used in pulsator washing machines because they do not provide acceptable spin-drying speeds for drum washing machines.

Ordinary motors always have a type of motor, which is also in the field of washing machines. It is a series motor. The series motor is small in size, but the power is large, and the noise is relatively large. At the same time, there is a carbon brush inside the series motor, which often wears out slowly with use. It is also accompanied by strong electromagnetic interference during work. Therefore, although this type of motor is very powerful, it is not as suitable for washing machines as other motors.

At present, most of the drum washing machines use DD direct drive motors or BLDC motors. Next, I would like to introduce the two washer motors used in the inverter washing machine.

DD Washer Motor is short for the direct drive "Direct Driver". Under the control of the drive system, the direct drive motor directly connects the washer motor to the load and drives the load. The advantage is that its output torque is large, so it can be directly connected to the moving device inside the drum, without connecting through gears, gear boxes, belts and other equipment.

DD motors are generally equipped with higher resolution encoders, plus the direct drive does not require the connection of components, DD washer motor greatly improves the range of speed regulation, and responds faster to speed changes. Since there is no need to go through multiple devices, the resonance caused by the motor during operation is reduced, and the noise is further reduced, further improving the efficiency. Since the connecting parts are reduced, the service life of the motor as a whole is greatly improved. On the other hand, because the structure of the DD motor is different from other motors, it is necessary for the washing machine manufacturers to further adjust the installation mode, which also increases the cost. Therefore, DD direct drive motors are often used in high-end products.

BLDC is short for "Brushless Direct Current", which is a brushless DC motor. The brushless "brush" refers to a brush mounted on the stator of the motor, and its function is to alternate the current direction through the coil. The BLDC motor uses an electronic commutator that responds quickly to operation and has a large starting torque. The brush on the stator often generates sparks due to friction when the motor is working. The toner generated by the friction will also damage the internal parts, and the BLDC motor that eliminates the brush interference has the low cost of the DC brush motor with high efficiency. However, it is worth mentioning that the BLDC motor still uses the traditional belt connection method, which is easy to slip in the case of water vapor.
