ABSTRACT:
An electric supercharger is described comprising a centrifugal blower for compressing air. The blower is mounted on one end of a shaft. A first bearing is provided for supporting the blower on said one end of said shaft in a cantilever fashion. The rotor of an electric motor is mounted on the opposite end of said shaft. A second bearing is provided for supporting the rotor on said opposite end of the shaft in a cantilever fashion. A lubricating fluid container is located between the first and the second bearings for containing a quantity of lubricating fluid. A slinger is also mounted on the shaft, which passes through the lubricating fluid container, for slinging the lubricating fluid against the first and second bearings. The motor, which is a brushless d-c motor, is designed to provide in response to a 50 to 100 volt applied potential, approximately 10 horse power at approximately 60,000 rpm's.
