Contact UsI want to control motor speed with capacitors
If a small induction motor has a non-linear load, such as a fan, you can somewhat control the motor speed by reducing the motor voltage. In that case the motor no longer has sufficient torque to maintain its speed and starts operating at a lower speed, with a large amount of slip between the synchronous speed and the actual speed.
