2. The role of air conditioning motor
Air conditioning motor is one of the important electrical components in air conditioning equipment. The functions of the air-conditioning motors commonly used in air-conditioning equipment are: driving the fan to rotate, strengthening the heat exchange effect through forced convection of the air, enhancing the flow of indoor cold/hot air, and driving the air pendulum to change the direction of the flow of cold/hot air. It is used for fresh air. For the central air conditioner, the air conditioner motor is also used to drive the water pump.
3. Working principle of air conditioner motor
The working process of the air conditioning motor is: when there is a phase winding being excited, the magnetic flux flows from the positive phase teeth, through the soft iron core rotor, and flows to the negative phase teeth with the shortest path strength, while the other six convex teeth have no magnetic through. In order to make the magnetic path force shortest, under the action of the magnetic field force, the rotor is forced to move so that the closest pair of teeth is aligned with the excited one.
