Abstract

An apparatus for providing pressurized liquid for operating a hydraulically operated device of an airplane comprises a pump for pumping liquid, a high speed flood cooled permanent magnetic motor for driving the pump, a drive connecting the motor to the pump for driving the pump with the motor, and a control for operating the motor as a variable speed motor. The pump, motor, drive and control are incorporated in one unit. Fluid passages in the unit circulate liquid being pumped by the drive through the pump case, control and motor for cooling. The motor includes stator and a rotor with an airgap therebetween having a thickness of at least 0.1 inch for reducing hydraulic friction losses in the motor without increasing motor size considerably.
