  • Combination motor and pump assembly
    Patent number: 5649811
    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.
