If you say what is the heart of the washing machine, it must be the motor. It is because of its existence that it can bring strong power to the washing machine. So how do we choose a wide variety of motors on the market? Next, Xiaobian will explain several common motors on the market.
First let us take a look at the 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.
