Abstract
An electric rotating machine, which can be operated as either a motor or generator, utilizes material exhibiting a Hall effect to replace the normal slip rings or mechanical commutation devices. Preferably, a slab of Hall effect material is curved to extend circumferentially around the rotor between the rotor and stator, and the rotor is adapted to create a magnetic field. When used as a motor, a source of electrical power is connected to the Hall effect material to cause a primary current to flow therein. The combination of the rotor magnetic field and the primary current flowing in the Hall effect material produces a Hall effect current which creates a torque on the rotor causing it to rotate. When used as a generator, the rotor is rotated and induces a primary current to flow in the Hall effect material. The combination of the rotor magnetic field and the induced primary current produces a Hall effect voltage and current that can be connected to power an electrical load.
