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.

Applications of induction motor?
A single phase induction motor is mainly used in fans.It is capacitor start capacitor run induction motor.In three phase induction motor squirrel cage induction motor is mainly used in elevators,lifts,cranes.slip ring induction motor is mainly used in electrically driven ships.
What type and Capacity of Electric Motor is used in Printing Press?
capacitor start induction run motor
What motor is used for lathe spindle?
Single phase induction motor ( usually capacitor- start type)
What motor is used for running lathe spindle?
Single phase induction motor ( usually capacitor- start type)

zma da ghan mata sa razeEven if I do not understand the language used above I still believe that the answe above is very irrelevant, to say the least.Answer:1. Resistance start single phase motor2. Capacitor start single phase motor3. Capacitor start and run single phase motor4. Capacitor start capacitor run single phase motor
What is the type of motor used in running a lathe spindle?
230V/1Ph/50Hz 1HP (0.75 kW)Motor Capacitor start induction motor ( single phase)
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 type of motor is used in a fan?
A capacitor start motor is used in a ceiling fan.
Are any capacitor in three phase induction motor?
There doesn't have to be but capacitors are sometimes used to correct the power factor.
What is the advantage of the capacitor-start induction-run motor over the resistance-start induction-run motor?
A capacitor-start system will limit the current drawn by an induction machine by correcting the devices poor power factor during the start up. This limits the current needed to start the device without using any real power. A resistance-start system will limit the starting current by drawing current unto the resistor instead of the induction machine. The real power used by the resistor is turned into heat and lost. A capacitive-start system will use no real power and will not create excess heat, it will be more expensive to initially purchase.
What is the function of a capacitor in motor circuit?
Mostly capacitor is used in the induction motors to improve the power factor , and make them to work as a self starting machine. In the small size , capacity dc motor has capacitor across it to smooth running without spark
