Function Of Capacitor In Single Phase Induction Motor

December 09, 2019

Capacitor start induction motor a capacitor start motors are a single phase induction motor that employs a capacitor in the auxiliary winding circuit to produce a greater phase difference between the current in the main and the auxiliary windings. In ideal case the additional auxiliary winding of a stator with a capacitor create a phase difference of 90 degrees to the main winding.

Since single phase induction motors are not self starters caused by discontinuty in stator mmf.

Function of capacitor in single phase induction motor. Fan is a capacitor start capacitor run single phase induction motor. The name capacitor starts itself shows that the motor uses a capacitor for the purpose of the starting. 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.

So to make it self start we can use capacitor capacitor also provides high starting torque. A motor capacitor such as a start capacitor or run capacitor including a dual run capacitor is an electrical capacitor that alters the current to one or more windings of a single phase ac induction motor to create a rotating magnetic field. Click here to view a capacitor start motor circuit diagram for starting a single phase motor.

Learn how a capacitor start induction run motor is capable of producing twice as much torque of a split phase motor. Capacitor produces the torque that makes a90 degrees out of phase between the starting auxiliary winding and the running main winding. Also read about the speed torque characteristics of these motors along with its different types.

So to iniate rotation single. Single phase induction motor is not the self starting.
