Abstract: A combination motor and pump assembly comprising a housing, a shaft rotaty mounted in the housing, and an impeller fixed to the shaft in the housing, said impeller comprising alternately magnetically polarized portions. The assembly further comprises stator means fixed in the housing adjacent the impeller, the stator means comprising an array of pole pieces and windings associated therewith for receiving electrical alternating current. Fluid inlet means and outlet means are provided in the housing in communication with the impeller. The impeller reacts to current received by the stator means as a motor rotor and rotates in response to excitation of the pole pieces by the current. The rotation of the rotor serves to move fluid in the housing from the inlet to the outlet means.

Abstract: An integrated motor/marine propulsor is provided having an electric motor apted for converting electrical energy into hydropropulsive energy. The electric motor comprises at least one stator assembly disposed in magnetomotive relation to a rotor. The rotor of the present invention advantageously includes a plurality of rotor blades wherein a portion of at least one of the rotor blades comprises a permanent magnet.

Abstract: A torque/force transfer apparatus which includes an annular ring having tein permanent first magnets side by side about the interior of the ring. The first magnets are arranged so as to alternate in polar orientation to present an inside circumference of alternating north and south magnetic poles. A cylindrical central member has therein permanent second magnets side by side about the exterior of the central member. The second magnets are arranged so as to alternate in polar orientation to present an outside circumference of alternating north and south magnetic poles. A strut assembly is pivotally attached to a center of a side of the central member and has arms extending radially outwardly from the central member center and is provided with planetary members rotatably connected each to one of the arms.
