Model of a rotating magnetic field electric motor
Dating18 June 1928
Maker PHYWE
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.
