Abstract
A low collapse speed, self priming, lubricating oil pumping system for a turbomachine, operatively driven by the turbine main shaft, is disclosed. In a preferred form, the invention includes a permanent magnet generator operatively coupled to shaft of the turbine-generator or turbomachine being lubricated and driven thereby to produce an electrical output; an induction motor directly connected to the electrical output of the permanent magnet generator without intervening protective devices such as fuses, switches, and so forth; and a positive displacement pump located in or in proximity to an oil reservoir and driven by the induction motor to pump oil from the reservoir at a flow rate and pressure sufficient to supply oil to the turbine-generator or turbomachine during all operating phases thereof during which lubrication is required.
