when the rotor of a three-phase induction motor is blocked, its rotor frequency will be same as the supplied frequency.
What is induction motors?
- An induction motor, also known as an asynchronous motor, is an AC electric motor in which the magnetic field of the stator winding is used to electromagnetically induct the electric current into the rotor necessary to produce torque.
- Therefore, it is possible to construct an induction motor without electrical connections to the rotor.
- When a load needs to be controlled in speed, they are used.
- Induction motors with wound rotors or slip rings are frequently used in conveyors, elevators, cranes, plunger pumps, crushers, and compressors.
