why we used capacitor in induction motor?
Answers were Sorted based on User's Feedback
Answer / m s kumar
Since induction motors have inherently low power factor,
Capacitors are used to improve the power factor. In
fractional hp motors, they are used in the starting winding
to temporarily convert the motor into 2ph motor to make it
self starting

Answer / gunasekaran
To improve the power factor of the motor. motor is inductive
load it draw reactive power from system.so we have
compensate the reactive power component from capacitor.for
single phase motor capacitor used for stating purpose
also.and single phase motor are low power factor motor
because due to large air gap B/W stator and rotor so it draw
more current from system.so capacitor are use in induction

Answer / manish
To run the motor,stating torque and current needs to start
the motor and this capacitor work as residual magnetesim
for the motor at stating point.
