| This model explains the functioning of the asynchronous electric motor (also called rotating magnetic field electric motor). By placing in an appropriate manner some coils with alternate current running inside, a magnetic field spinning with a certain angular velocity is generated within the stator. The rotor, from which comes out the motor shaft, chases the magnetic field realizing the mechanical torque. The first who achieved a rotating magnetic field electric motor was Galileo Ferraris in 1885, but it was Nikola Tesla that patented the three-phase AC motor in 1888. |
