摘要： An electrical motor includes a motor case inside which an inner space is formed, a bearing disposed so as to pass through a wall of the motor case, a rotor shaft rotatably supported by the bearing, and an earth conductor that is fixed with the motor case and includes a frame and an electrical conductor provided on the frame. The frame has an annular or curved inner circumferential surface along an outer circumference of the rotor shaft and is fixed with the motor shaft. The electrical conductor is disposed on the inner circumferential surface of the frame so that an end of the electrical conductor is slidably contacted with the rotor shaft. A bypass flow passage is provided between the earth conductor and the motor case. The inner space and an outside of the motor case are communicated with each other via the bypass flow passage. According to the electrical motor, its inside can be cooled without damaging the earth conductor.

摘要： A turbo compressor includes a housing in which lubrication oil is accumulated, a gear that is housed in the housing and to which the lubrication oil is supplied, a demister that is disposed above the gear and on which an intake is provided to catch oil mist of the lubrication oil in the housing, a gear cover that is provided surrounding the gear to catch lubrication oil splashed by the gear and then drip the caught lubrication oil downward, and a demister cover that is disposed near the demister to drip the lubrication oil caught by the demister downward. Here, a narrow gap is formed between the demister cover and an inner wall surface of the housing. According to the turbo compressor, an amount of lubrication oil flowing through the demister can be reduced by the gear cover and the demister cover.
摘要翻译：本发明提供一种涡轮压缩机，其具备：积存润滑油的壳体;收容在壳体内并供给润滑油的齿轮;配置在齿轮的上方且设置有吸入油雾的减雾器; 壳体内的润滑油，围绕齿轮设置的齿轮盖，以接收由齿轮喷溅的润滑油，然后向下滴落被捕获的润滑油;以及除雾器盖，设置在除雾器附近以滴落由除雾器向下。在此，在除雾器盖和壳体的内壁表面之间形成狭窄的间隙。根据涡轮压缩机，通过齿轮盖和除雾器盖可以减少流过除雾器的润滑油的量。

摘要： An electrical motor includes a motor case, a rotor that is housed in the motor case and rotatable about a rotor shaft, a stator that is provided around the rotor in the motor case and configured by winding a stator coil around a stator core, and a first spray nozzle that is provided in the motor case for spraying liquid coolant toward an inner circumferential surface of the motor case. The stator coil has a first coil end protruded from the stator core along a direction of the rotor shaft. The first spray nozzle is configured to spread the coolant as mist by splashing the coolant on the inner circumferential surface to make the spread mist over the first coil end. The first coil end can be cooled sufficiently by vaporization heats of the refrigerant mist that is fallen over it.

摘要： A turbo-compressor 1 includes a variable vane 3 that adjusts the flow rate of a fluid, a drive shaft 5 that is connected to the variable vane 3 and is rotated to drive the variable vane 3, a motor 7 that rotationally drives the drive shaft 5, and a coupling 11 that couples the drive shaft 5 with an output shaft 9 of the motor 7. Between the drive shaft 5 and output shaft 9 and the coupling 11, a vibration isolation means 13 is arranged to connect the drive shaft 5 and output shaft 9 to each other so that they rotate together and allow the drive shaft 5 and output shaft 9 to move in a vibration direction.
