An induction motor also known as an asynchronous motor is a generally used AC electric motor. For an induction motor, the electrical current or AC in the rotor needed to produce torque is gain through electromagnetic induction from the rotating magnetic field of the stator winding. The rotor of an induction motor can be used as a squirrel cage rotor.
Why Does The Rotor Rotate
When the three-phase power supply to the stator. This current flows to the stator winding(conductor). Then it produces magnetic flux and it’s rotated to the clockwise direction around the conductor. Magnetic flux induced to the rotor bar by the electromagnetic induction law. For this flux rotor received magnetomotive forces and the rotor build up rotating torque.
Finally, the rotor rotates a similar direction to magnetic flux.
why the induction motor is called an induction motor?
An induction motor has a two-part Stator and Rotor. No magnetic and electric connection between them. Electric flux induced to the rotor by the Faraday’s law electromagnetic induction. For that, the induction motor is called the induction motor.
