Information

1. Voltage regulation and speed regulation

The method of changing the stator voltage of the Air conditioner motor to achieve speed regulation is called voltage regulation and speed regulation. Voltage regulation and speed regulation, for single-phase air conditioner motor, it can be a certain value between 0~220V; for three-phase air conditioner motor, it can be a certain value between 0~380V. For voltage regulation transformers, if the voltage regulation of the transformer is stepped, the speed regulation of the air conditioner motor is also stepped. If the voltage regulation of the transformer is stepless, then the speed regulation of the air conditioner motor is also stepless.

2. Pole change speed regulation

Change the wiring method of the stator winding of the air conditioner motor to change the number of pairs of magnetic poles of the air conditioner motor, so that the synchronous speed can be changed in stages, and the speed of the air conditioner motor can be adjusted in stages. This speed-regulated Air conditioner motor currently has a series of stereotyped products for selection, such as single-winding multi-speed Air conditioner motor.

3. Electromagnetic speed regulation

The method of realizing speed regulation through electromagnetic slip clutch is called electromagnetic speed regulation. Electromagnetic speed regulation asynchronous Air conditioner motor (commonly known as slip Air conditioner motor) is a simple and reliable AC stepless speed regulation device. The air conditioner motor adopts a combined structure, which is composed of a drag air conditioner motor, an electromagnetic slip clutch and a tachogenerator. The tachogenerator acts as a speed feedback signal source for control.
