10. Starting Method for Induction Motors
www.uotechnology.edu.iq10. Starting Method for Induction Motors A 3-phase induction motor is theoretically self starting. The stator of an induction motor consists of 3-phase windings, which when connected to a 3-phase supply creates a rotating magnetic field. This will link and cut the rotor conductors which in turn will induce a current in the rotor conductors and

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
