Its principle is that it has both the main winding, auxiliary winding and centrifugal switch. The auxiliary winding works with the main winding, which is similar to that of the first kind. But how can the startup performance be reduced?
They through the centrifugal switch, this switch is a double throw switch, so the start time, on a large capacity capacitor (commonly known as the starting capacitor we know the capacitance increases, phase current is, the better starting performance, but too much will be winding fever) to the motor.
That is, in the low speed motor, incorporated using a large capacitor current, rated current of the capacitor provided are usually more than winding, such high current is driven by the rotating magnetic field is very strong, so as to drive the rotor to rotate high torque output button
