Such motors are used whenever a single phase power supply is more practical than a three phase power supply such as in domestic appliances. It produces the torque that makes a90 degrees out of phase between the starting auxiliary winding and the running main winding.

What is the use of capacitor in single phase motor. One often used method is the split phase motors. They are not as efficient as three phase ac induction motors however. Motor start and run capacitors are used in single phase ac induction motors.

Capacitor start induction motor in the figure below a larger capacitor may be used to start a single phase induction motor via the auxiliary winding if it is switched out by a centrifugal switch once the motor is up to speed. The answer is that as the single phase induction motor is not self starting so the capacitor is used to make single phase induction motor self starting. Capacitor is used for starting single phase induction motors.

Another method is the capacitor start induction run motors. 2 determine the voltage rating for capacitor. We know about the activity of a capacitor in a pure ac.

Hope to give you an idea. The single phase induction motor can be made to be self starting in numerous ways. So in an induction motor a two phase supply has created from a single phase supply with the help of additional starting windings or auxiliary winding along with a capacitor.

When we select the voltage rated for capacitorwe must know the value of our power supplyfor safety purposemultiply the voltage of power supply with 30factors that affect the selection of the proper voltage rating of the capacitor include. The capacitor is used to make a single phase motor rotate in one direction only by supplying a phase shifted voltage to a starting winding on the motor. In ideal case the additional auxiliary winding of a stator with a capacitor create a phase difference of 90 degrees to the main winding.

You may notice that every single phase induction motor except shaded pole induction motor need one or more capacitor.
