초록

A combination of a variable reluctance motor and a screw compressor is provided with a fluid management system that directs a portion of the lubricant flow through the variable reluctance motor to cool its stator laminations and windings. Another portion of the lubricant flow is caused to pass directly from a heat exchanger to the screw compressor. The first portion of flow, which passes through the variable reluctance motor, is then directed into fluid communication with the inlet of the screw compressor to lubricate the screw compressor and provide coo...
