Abstract An electromagnetic motor is disclosed incorporating a plurality of rotatably mounted shafts each of which carries a plurality of individual rotors and is supported by a plurality of individual stators. The rotors and stators each incorporate electromagnets which provide the drive torque. At least one switch structure is provided on each of the shafts for synchronously controlling the currents in the electromagnets of the stators on the individual shaft so as to establish repeating cycles of attraction and repulsion in association with the magnets of the associated rotors. The aligned rotor elements on each shaft are offset from those on the other shafts so as to establish a continuity of drive torque, the shafts being mechanically coupled together through a gearbox which is in turn coupled to a drive shaft. By providing an offset relationship between the magnetic elements of the different shafts, a continuity of drive torque is established; however, the aligned electromagnets on each shaft enable double-ended operation for each internal electromagnet (excepting those of the ends).
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 for mutual rotation; a like plurality of rotors each supportably affixed 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 like 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 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; and a like 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.
