Document Type and Number:

Japanese Patent JP5837997

Kind Code:

B2

Abstract:

An apparatus and method for cooling a compressor motor (152) having a motor stator (162) and cooling a rotor (166) in a refrigerant system (100). The method cools the rotor and the stator, electromagnetic bearings (160) located within a compressor housing by providing refrigerant liquid to the stator internal channels, the channels being in fluid communication with a rotor passageway (172), and a flow-control device (168) controlling refrigerant flow into the stator. A temperature monitoring device (176) in communication with a controller (140) monitors motor temperature. The controller (140) evaluates the motor temperature and adjusts refrigerant flow through the flow control device (168), maintaining the motor (152) within a predetermined temperature range.
