A capacitor fed winding on a single phase motor produces a phase shifted magnetic field that induces a starting torque in the rotor. Once sufficient RPM is achieved a centripetal switch disengages the start capacitor and, depending on design, switches in a run winding/capacitor, and running conditions are maintained from there.
This is necessary as, without the extra winding, the induced current/magnetic field in the rotor would only be 180 degrees out of phase with respect to the field, and the rotor would not turn. Once the rotor is turning, a constant "slip" is maintained which keeps the rotor turning.

What is a CSIR motor?
A CSIR motor stands for Capacitor Start-Induction Run motor, which is a type of single-phase induction motor commonly used in household appliances like refrigerators and air conditioners. It uses a capacitor to provide the starting torque needed to initiate rotation, then operates as a standard induction motor once up to speed.
Is a run capacitor the same as a start capacitor?
No, they are two different concepts. The start capacitor is used in conjuction with a starting winding on a single-phase induction motor to produce a small component of rotating field inside the motor. This ensures it rotates the desired way. The run capacitor is used to correct the power-factor of the motor, which reduces the current drawn from the supply for the same amount of power.
What is the common application for capacitors in electric motors?
There are 2 types of capacitor including starting capacitor and running capacitor running capacitor are used to improve the power factor of motor. starting capacitor used in split phase induction motor . starting capacitor may isolate from motor,s starting winding through of centrifugal switch after getting motor 90% of it,s rated speed.
What are four types of single phase motors?
Some examples of single-phase motors include split-phase, capacitor-start, shaded pole, and permanent split capacitor (PSC) motors. Each type has its own unique design and application, offering different characteristics and performance capabilities.
What type of motor is used in a fan?
A capacitor start motor is used in a ceiling fan.
What device is used to disconnect the start windings for the circuit in most nonhermetically sealed capacitor start induction run motors?
In most non-hermetically sealed capacitor start induction run motors, a centrifugal switch is used to disconnect the start windings from the circuit. This switch operates based on the motor's speed, activating at a certain RPM to disengage the start winding once the motor reaches operational speed. This mechanism helps improve efficiency and prevents overheating of the start winding during normal operation.
Are any capacitor in three phase induction motor?
There doesn't have to be but capacitors are sometimes used to correct the power factor.
