Webb13 apr. 2024 · The slip frequency is the difference between the synchronous speed of the motor's magnetic field and the actual rotor speed. When the rotor is stationary, the slip frequency is equal to the synchronous frequency of the power supply, typically 50 or 60 Hz. As the rotor begins to turn, the slip frequency decreases, causing the motor to speed up ... Webb31 maj 2024 · However, the number of poles here are defined, they are selected according to the speed required. The stator produces an alternating flux when fed with 3-phase supply which revolves with synchronous speed(N s = 120f / P). b) Rotor: It is a rotating part of an induction motor. The types of rotor used are listed below.
