Single-phase motor series connected capacitor speed regulating three-speed circuit
Source: InternetPublisher:难得正经 Updated: 2017/07/27
For some single-speed motors, capacitors C1 and C2 can be added as shown in the figure. Changed to three speed motor. C1 and C2 must use paper capacitors or oil-immersed paper capacitors. The capacitance is directly related to the speed of the motor.
