1. The general size of the starting capacitor of the air conditioner compressor
The power of the motor is different, and the size of the capacitor capacity is different. and run. The electric motor used in the air conditioner is the same as the electric fan, which is a single-phase capacitive motor. It must rely on the capacitor to form a phase difference of the current between the two coils of the motor, so that the motor can rotate. So do you know how big the starting capacitor of the air conditioner compressor is?
The capacitor used in a 1.5-horse air conditioner compressor is generally about 30 microfarads. The starting capacitor of the compressor is selected according to the compressor specification. Sometimes when the voltage is unstable, you can choose a larger capacitor or add an auxiliary starting capacitor to help start.
Second, what if the starting capacitor of the air conditioner compressor is too large?
The capacitor is the key component to start the air conditioner motor. Most of the air conditioners on the market now have The capacitor is used to start the air conditioner and take into account the operation. The damage of the capacitor will cause the compressor starting current to rise too quickly, and the protection mode will automatically be turned on to stop or the compressor cannot be started, which will cause the air conditioner to fail to operate normally or automatically power off during the startup process. So what about the specific air-conditioning compressor starting capacitor that is too large?
The larger the capacitor of the air-conditioning compressor, the higher the current and the lower the voltage. It is better to choose the capacitor of the same specification. If it is smaller, the starting torque will be insufficient and the starting time will be prolonged, which is harmful to the compressor. If it is too large, it will cause the compressor to overheat, and the compressor starting coil will not be able to withstand it, which will easily burn out the compressor coil.
