to start the motor and give more current to motor to run
The single phase induction motors are made self starting by providing an additional flux by some additional means. Now depending upon these additional means the single phase induction motors are classified as: 1.Split phase induction motor. 2.Capacitor start inductor motor. 3.Capacitor start capacitor run induction motor. 4. Shaded pole 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.
Single phase induction motor ( usually capacitor- start type)
Single phase induction motor ( usually capacitor- start type)
fan is a capacitor start capacitor run single phase induction motor. since single phase induction motors are not self starters, caused by discontinuty in stator mmf. so to iniate rotation single phase supply is splitted 90 degree apart by a capacitor to convert it to a 2 phase motor, which produces a continued synchronously revolving mmf in stator to start the motor. cool !!
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.
if you are asking about ordinary fans(used in home) . They consist single phase induction motor which require a capacitor for starting because single phase induction motar con not generate rotating tark to rotate the fan automatically
230V/1Ph/50Hz 1HP (0.75 kW)Motor Capacitor start induction motor ( single phase)
how reversing an ac single phase induction motor to wark as induction generator
I have never come across a three phase capacitor start motor. Any three phase motors I have worked on are induction start.
Starting capacitors are only required for single-phase induction motors. They are not necessary for three-phase motors.
