ABSTRACT:
A motor pump wherein the motor is a variable reluctance motor having a rotor which functions as an impellor to provide pumping action as a result of centrifugal force acting upon a fluid supplied to the motor pump. The motor pump is extremely simple in that it has only one moving part, its rotor, which is formed of a plurality of ferromagnetic elements spaced from one another with flow passages located between the elements. Fluid enters the pump on the radially inner side of the ferromagnetic elements and flows radially through the flow passages to the pump discharge outlet.
