ABSTRACT:
An improved electric motor design wherein the stator and rotor configuration is arranged to produce a core flux efficiently shaped and utilized to enhance motor torque without substantially increasing the electrical power furnished to the motor. The internal surface of the stator, or coil, has a plurality of corrugations and annular grooves formed therein and a corresponding number of rotor disks having permanent magnets secured to the outer surface, the permanent magnets being positioned to rotate within the grooves. The magnets are opposed in polarity disk to disk as well as being offset about the circumference so that one disk set will align with one set of corrugations and the other disk set align with the pole face created by the intersection of the corrugations and the adjacent annular grooves. Energizing the motor coil with alternating current causes the magnets and their associated disks to reposition themselves in a manner that causes the motor shaft to rotate as well as shaping the core flux field for more efficient use thereby increasing motor torque.
