Varying run capacitor for speed control of single phase motor
Changing the capacitor value changes the amplitude and phase shift of the current in the auxiliary winding. Reducing the capacitor value lowers the torque values of the torque vs. speed curve as shown below. This method of speed control is often used for fans, because the torque requirement of a fan is lower at lower speed.
