Jul 02, 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
• The basic idea of an electric motor is to generate two magnetic fields: rotor magnetic field and stator magnetic field and make the stator field rotating The rotor will constantly be turning to align its magnetic field with that of the stator field • The 3-phase set of currents, each of equal magnitude and with a phase
