The first type, the split-phase starting type, as shown in Figure 1, is assisted by an auxiliary starting winding, and its starting torque is not large. The operating rate remains roughly constant. It is mainly used in electric fans, air conditioning fans, motors, washing machines and other motors.
Second, when the motor is stationary, the centrifugal switch is turned on, and the starting capacitor participates in the starting work after the power is given, and the centrifugal switch will automatically jump away when the rotor speed reaches 70% to 80% of the rated value, and the starting capacitor completes the task and is disconnected. The starting winding does not participate in the running work, while the motor continues to act by running the winding coil, as shown in Figure 2.
Third, when the motor is stationary, the centrifugal switch is turned on, and the starting capacitor participates in the starting work after the power is given, and when the rotor speed reaches 70% to 80% of the rated value, the centrifugal switch will automatically jump open, and the starting capacitor completes the task and is disconnected. The running capacitor is connected in series to the starting winding to participate in the operation. This method of connection is generally used in places with large and unstable loads, such as air compressors, cutting machines, and woodworking machine tools.
