2. The role of air-conditioning motor
Air-conditioning motor is one of the important electrical components in air-conditioning equipment. The functions of air-conditioning motors commonly used in air-conditioning equipment are: driving the fan to rotate, strengthening the heat exchange effect by forced convection of air, strengthening the flow of indoor cold/hot air, and driving the air pendulum to change the direction of cold/hot air flow. It is used to change the fresh air. For the central air conditioner, the air conditioner motor is also used to drive the water pump.

3. Working principle of air-conditioning motor
The working process of the air-conditioning motor is: when the phase winding is excited, the magnetic flux flows from the positive phase teeth, passes through the rotor of the soft iron core, and flows to the negative phase teeth with the shortest path strength, while the other six convex teeth are not magnetic. through. In order to minimize the magnetic path strength, the rotor is forced to move under the effect of the magnetic field force, so that the nearest pair of teeth is aligned with the excited one.
