Axial Field Electric Motor and Method
Abstract
It is therefore a general purpose and primary object of the present invention to provide an improved axial field electric motor. It is a further object of the present invention is to provide an improved electric motor for high power density applications. A hybrid field, brushless, permanent magnet electric motor utilizing a rotor with two sets of permanent magnets oriented such that the flux produced by the two sets of magnets is perpendicular to each other. A plurality of axial flux permanent magnets are positioned radially interiorly of a plurality of radial flux permanent magnets. Axial stators interact with the axial flux permanent magnets. A radially positioned stator interacts with radial flux permanent magnets. In one configuration, an electronic feedback system is created that magnetically clamps and holds the hybrid rotor in its axially centrally aligned position, thereby reducing axial vibrations.
