What is the principle of Air conditioner motor? Let's analyze it together.
Air conditioner motor is generally a single-phase asynchronous motor with PSC wiring. According to the needs of use, the air conditioner motor can adjust the speed. The speed adjustment methods include: stator winding tap speed adjustment, silicon speed adjustment, etc.

1. Control the tap speed.
By changing the number of turns of the motor stator winding and changing the working voltage of the main winding, the purpose of changing the magnetic flux and adjusting the speed is achieved. The stator winding of the PSC motor is composed of three parts: the main winding, the auxiliary winding and the middle winding (speed control winding).

2. Thyristor speed regulation.
Thyristor, also known as thyristor, has two types: unidirectional thyristor and bidirectional thyristor. The characteristic of unidirectional thyristor is that when the thyristor is subjected to a forward anode voltage, a forward voltage is applied to the gate, and the element is turned on when there is a certain gate current.
When the pipelines are connected, the literary drama quickly loses its effect. The thyristor only cuts off the pipe when the positive anode voltage drops to a certain value or when the anode voltage is negative. Air conditioner motor triac feature, when the voltage drops below the lower voltage of the holding channel or reverses when the pipe is turned on, the pipe will be cut off until the next trigger signal (pulse signal) arrives.
Solid State Relays: Solid State Relays (SSRs) are non-contact semiconductor relays that use triacs. When a trigger signal is given at the input, the photothyristor will cut off the load.
In the speed regulation of the air conditioner motor of the air conditioner, the output level of the single-chip microcomputer is used as the trigger signal of the solid state relay, and the zero point of the power frequency sinusoidal current is detected by the auxiliary circuit, and the timing is controlled by the program, and then the current of the load is turned on at a certain time.
When the power supply current exceeds 0, the thyristor will automatically cut off, so as to obtain the effective voltage of the required load. When the voltage is supplied to the motor, the corresponding speed can be obtained by changing the motor winding voltage.
The micromotor used in the swing blade device of the air conditioning discharge door is a permanent magnet synchronous claw pole self-starting synchronous motor. The driving voltage of the air conditioner motor is ~220V/50Hz, and the stator consists of a cup shell, an annular single-phase coil and a claw disc. The rotor is a ferrite ring with high corrective force.
The claw poles are evenly distributed along the circumference, and the number of claw pole pairs (pole pairs) is determined by the desired synchronization rate. The swing motor has many claws, low speed, high torque, low output power, simple structure, and no fixed rotation. The main switch of the Air conditioner motor is usually installed on the control panel of the air conditioner. This is the power switch for connecting the compressors, fans and other actuators, and it is also an optional switch for switching the running state of the air conditioner.
