17-04-2022 · One of the fundamental characteristics of an AC induction motor is that the rotor spins at a slower rate than that of the stator's rotating magnetic field. This difference in speed between the rotor and the stator's magnetic field is known as slip. Slip allows the motor to produce torque — the higher the slip, the higher the torque production, but also, the lower the …
