Information

The manufacturer of Household mobile air conditioning motor tells you that the motor used for the fan of the air conditioner is generally a single-phase asynchronous motor, and adopts the PSC wiring method. According to the needs of use, the speed of the fan motor can be adjusted, and the speed adjustment methods include: stator winding tapped speed regulation, thyristor speed regulation, etc.

1. Tap type speed regulation
The manufacturer of Household mobile air conditioning motor tells you to change the working voltage on the main winding by changing the number of turns of the stator winding of the motor, so as to achieve the purpose of changing the magnetic flux and adjusting the speed. The stator winding of the PSC motor with tap speed regulation is composed of three parts: the main winding, the auxiliary winding and the middle winding (speed regulating winding).
2. SCR speed regulation
The thyristor, also known as the thyristor, has two types: unidirectional thyristor and bidirectional thyristor. The characteristics of unidirectional thyristor are that when the thyristor is subjected to a forward anode voltage, a forward voltage is applied to the gate and there is a certain gate current. , the element is turned on.
When the tube is turned on, the gate will lose its function. The manufacturer of Household mobile air conditioning motor tells you that when the thyristor is turned on, only when its positive anode voltage decreases to a certain value or the anode voltage becomes negative, the tube is cut off.
Triac characteristics, when the tube is turned on, when the voltage drops below the minimum voltage to maintain conduction or becomes reversed, the tube will be cut off, and will not be turned on again until the next trigger signal (pulse signal) arrives.
Solid State Relay: Solid State Relay is abbreviated as SSR, which is a non-contact semiconductor relay using a bidirectional thyristor.
When a trigger signal is applied at the input, the photo-thyristor controls the load on and off.
The manufacturer of Household mobile air conditioning motor tells you that in the speed regulation of the fan motor of the air conditioner, the high and low levels output by the single-chip microcomputer are used as the trigger signal of the solid state relay, and the zero-crossing point of the power frequency sinusoidal current is detected through the auxiliary circuit, and the timing is controlled by the program. Then the current of the load is turned on at a certain time.
The manufacturer of Household mobile air conditioning motor tells you that the thyristor is automatically turned off when the power supply current crosses zero, so that the load can obtain the required effective voltage. If this voltage is supplied to the motor, the voltage of the motor winding can be changed to obtain the corresponding speed.
