Abstract
Abstract An electromagnetic motor which incorporates a plurality of shafts each of which carries individual rotors and is journaled within stators is provided with six rotors per shaft, each of which carries switching mechanisms spaced 60° apart. The rotors and stators each incorporate electromagnets to provide drive torque, and the aligned rotor elements on each shaft are offset from those of the adjacent shafts to establish a continuity of drive torque. The shafts are mechanically coupled at one end through a gear box, and at their opposite ends by a continuous belt, chain or gear system.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
254 words
An electric motor for providing rotary drive power from a source of electrical power, comprising: a plurality of rotatably mounted shafts; gearing means for interconnecting said shafts together to drive an output shaft; a plurality of rotors supported on each of said shafts, each of said rotors including a multiplicity of magnetic means polarly disposed parallel to the axes of rotation of said shafts; a plurality of stators each fixed in stationary relationship in combination with one of said rotors, each of said stators including a multiplicity of electromagnets having pole pieces therein, said electromagnets affixed in said stators to dispose said pole pieces in parallel relationship to the magnetic means of a related rotor, said pole pieces and said magnetic means of each of said stator and rotor combinations being offset in relationship to the pole pieces and magnetic means of each other stator and rotor combination to provide a staggered drive relationship between the stator and rotor combinations; a plurality of switching means, one being coupled to each of said shafts for supplying electrical current to said electromagnets in phase synchronization with the position of the rotors of each of said stator and rotor combinations whereby to propel said shafts; means for keying the rotors supported by alternate shafts to said shafts so that said alternate shafts are driven by said rotors, the remaining rotors being free wheeling on their respective shafts; and means for mechanically coupling adjacent shafts so that the said driven shafts drive adjacent shafts in the same direction.
