3 phase motor for grinding

  • 3 Phase Induction Motor Definition And Working Principle

    Nov 27 2019 · Thus from the working principle of three phase induction motor it may be observed that the rotor speed should not reach the synchronous speed produced by the stator. If the speeds become equal there would be no such relative speed so no emf induced in the rotor and no current would be flowing and therefore no torque would be generated.
