Web24 de fev. de 2012 · An induction motor (also known as an asynchronous motor) is a commonly used AC electric motor. In an induction motor, the electric current in the rotor needed to produce torque is obtained via electromagnetic induction from the rotating magnetic field of the stator winding. WebThe high resistance in the rotor decreases the starting current but increases the starting torque. As the induction motor picks up speed, the resistances gradually disconnect … greensill fcafc
