The flux control method is the convectional and the non-convectional method of speed control of an induction motor.

I need the answer of this question plz!!
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.
slip speed control refers to induction machines s=(synchronous speed-motor speed)/synchronous speed by varying slip the machine can be either be operate in generated mode or motor mode
The speed control of the DC motor is important because its speed can be changed over a wide variety of simple methods which is not possible in an AC motor.
How many methods can be used to control the speed of Single Phase Induction Motor? 1.injecting emf method 2.by frequency control method 3.induced voltage method
by motor starter
It is used for sensorless motor control. With vf speed control u can control speed of any induction motor.

induction motor has two control system one is stator control another rotor control And it comes under the category of asynchronous motors. The term induction is because the rotor of an a.c motor does not receive the electric power through conduction but by induction same as the secondary of the transformer receives the power from primary. And so an induction motor can also be called as a rotating transformer i.e. one in which primary is stationary and secondary is free to rotate.

Yes the Induction motor works on Electromagnetic induction principle.
I need the answer of this question plz!!
there are two methods i.e armature control method and field control method....
Induction motor is an AC electric motor which uses electromagnetic induction to induce the electric current in the rotor to produce torque.
AC 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.
