Abstract:
1. A compressor assembly for use in transporting natural gas, said assembly comprising: a natural gas compressor comprising at least one stage of compression, that increases a pressure of natural gas flowing therethrough; a permanent magnet-type super-synchronous motor coupled to said natural gas compressor for powering said compressor; a housing comprising an inner surface and an outer surface, said inner surface defines a cooling plenum and a compressor intake plenum, said compressor and said permanent magnet-type super synchronous motor both positioned within said housing; a suction header for supplying gas from a source upstream from said compressor assembly to said compressor assembly, said suction header coupled to said housing outer surface for channeling an inlet gas flow stream into said compressor intake plenum; and a cooling gas supply header coupled to said suction header such that a portion of the inlet gas flow stream upstream from said housing outer surface is diverted from said suction header and is channeled to said cooling plenum to facilitate cooling said permanent magnet-type super-synchronous motor.
