    Abstract: A cooling system for a motor powering a compressor in a vapor compression system includes a housing enclosing the motor and a cavity located within the housing. A fluid circuit circulates a cooling fluid in the motor, and includes a first connection in the housing to receive cooling fluid and a second connection in the housing to remove cooling fluid. The fluid circuit includes a passageway for cooling fluid positioned in an internal chamber formed in a motor shaft.

    Abstract: A cooling system is provided for a motor powering a compressor in a vapor compression system. The cooling system includes a housing enclosing the motor, and a cavity located within the housing. A fluid circuit circulates a cooling fluid in the motor, the fluid circuit having a first connection in the housing to receive cooling fluid, and a second connection in the housing to remove cooling fluid in fluid communication with the loop. The fluid circuit includes a passageway for cooling fluid positioned in an internal chamber formed in a motor shaft.

    Abstract: A motor coolant method and system is used to cool a compressor motor (36) in a refrigeration system having a multi-stage compressor (38). The compressor includes a first compressor stage (42) and a second compressor stage (44), the first compressor stage providing compressed refrigerant to an input of the second compressor stage. The motor coolant system has a first connection with the refrigerant loop to receive refrigerant into the motor cavity for cooling, the received refrigerant provided from a system component having a high pressure, and a second connection with the refrigerant loop to return refrigerant to an intermediate pressure greater than an evaporator operating pressure. The pressure inside the motor cavity may be approximately the pressure within the first stage discharge and second stage suction to minimized seal leakage between the motor cavity and the internal pressures of the first and second stage compressors.

    Abstract translation: 电动机冷却剂方法和系统用于冷却具有多级压缩机（38）的制冷系统中的压缩机电动机（36）。 压缩机包括第一压缩机级42和第二压缩机级44，第一压缩机级将压缩的制冷剂提供给第二压缩机级的输入。 电动机冷却剂系统具有与制冷剂回路的第一连接，以将制冷剂接收到电动机腔中进行冷却，从具有高压的系统部件提供的接收的制冷剂和与制冷剂回路的第二连接以使制冷剂回到中间压力 大于蒸发器的操作压力。 电动机腔内的压力可以近似为第一级排放和第二级抽吸期间的压力，以最小化电动机空腔与第一级和第二级压缩机的内部压力之间的密封泄漏。
