ABSTRACT:
An electric motor system comprising a rotor including permanent magnets providing a plurality of correspondingly directed magnetic poles angularly displaced around said rotor, a stator comprising first and second windings adapted to cooperate with the poles of said rotor, each of said windings having transversely disposed conductive portions for intercepting the magnetic fields of said poles during rotation of said rotor, and an amplifier having its input coupled to said first winding so as to be energized by alternating voltage induced in said first winding during rotation of said rotor, and having its output coupled to said second winding to supply alternating current therethrough in synchronism with the interception of the magnetic fields of said poles by the transverse portions of said second winding. A motor system in accordance with the invention is capable of achieving extremely high speeds of rotation particularly when the rotor structure is suspended by means of magnetic bearings well known in the art. Provision for limiting the speed of operation of the motor may be made comprising a low-pass filter included in the feedback path from the first winding to the second winding. Also provision may be made for initiating rotation of the rotor, which may comprise Hall effect sensors disposed adjacent to the transverse portions of the first winding, the outputs of which are combined and supplied to the input of the amplifier to cause alternating current to be supplied to the second winding to initiate rotation of the rotor.
