摘要： The invention provides a motor comprising a stator and a rotor. The stator core includes a laminated stator core made of laminated stator core plates in which straight cut surfaces are formed on a circular outer peripheral surface of the laminated stator core plates. The straight cut surfaces of the laminated stator core plates are circumferentially displaced every predetermined laminated stator core plates so that the straight cut surfaces are uniformly distributed in an axial and a circumferential direction of the laminated stator core. Therefore, a flow passage for lubricating oil is ensured, while local magnetic saturation of the stator core is dissolved and a cogging torque and an induced voltage waveform distortion rate are improved.

摘要： In a conventional compressor, since a motor and a mechanical section of the compressor are disposed in one and the same closed container, the motor is exposed to high-temperature coolant and heated, and the efficiency of the motor is lowered. Further, during the operation of the compressor, the coolant circulating in the refrigerating cycle conveys additional heat generated by the motor coil. Thus the efficiency of the refrigerating cycle is lowered. The compressor according to the present invention includes a compression chamber divided into a closed chamber and an open chamber separated by a magnetic induction plate from each other. The closed chamber is filled with high temperature and pressure coolant and the rotor of the motor is disposed in the closed chamber, and the stator of the motor is disposed in the open chamber.
摘要翻译： 在传统的压缩机中，由于电动机和压缩机的机械部分设置在同一个密闭容器中，电动机暴露于高温冷却剂并被加热，电动机的效率降低。 此外，在压缩机的运行过程中，在制冷循环中循环的冷却剂传递由电动机线圈产生的额外的热量。 因此，制冷循环的效率降低。 根据本发明的压缩机包括分为密闭室的压缩室和由磁感应板彼此隔开的开放室。 封闭的室内装有高温高压的冷却剂，电机的转子设置在封闭的室内，电动机的定子设置在开放的室内。
