Abstract:
An electric motor apparatus and method of controlling the same are provided. The electric motor apparatus includes a stator and a rotor rotationally mounted coaxially with the stator; an intermediate screen having a magnetic material and rotationally mounted between the stator and the rotor to provide magnetic screening between the rotor and the stator; and control circuitry to control power supplied to windings on the rotor and the stator in dependence upon a desired output rotational speed.
