Gas Compressor Assembly

Abstract

A gas compressor assembly for compressing a gas includes a rotor having a rotational axis, a motor section and a compressor section arranged along the rotational axis of the rotor. The gas is supplied via an inlet. A first motor passageway directs the gas from the inlet to the motor section for cooling the motor section. A compressor passageway directs the gas from the motor section to the compressor section. The assembly also includes a gas-tight housing to enclose the rotor, a bearing section, the motor section, and the compressor section. The motor section includes a motor and a stator. The inlet is arranged such that a majority the gas flowing through the inlet is directed to the motor section through the first motor passageway wherein the gas cools the motor section before compression of the gas, to provide increased cooling of the motor and the stator.
