3-Phase Induction Motors - UNLV
www.egr.unlv.edu• 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
