ABSTRACT:
A compressor assembly including an electric motor and a compressor crankcase. The compressor crankcase includes a suction inlet. A motor casing is secured to the crankcase. The suction inlet is connected by means of a first passage to the interior of the motor casing. A baffle located in the motor casing causes a portion of the inflowing refrigerant suction gas to be diverted to flow over and cool the rear windings of the motor. The remainder of the inflowing gas is caused to flow over and cool the front windings of the motor. After flowing over the windings, the two portions of the suction gas are recombined and the suction gas is then caused to flow out of the motor casing to the compressor cylinder suction inlet.
