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： Oil separation from discharge gas of a screw compressor is performed with a demister provided in a discharge chamber. For solving unevenness in the speed distribution of the gas in the chamber, at least one auxiliary demister for oil separation is disposed at a local position immediately behind or near the downstream side of an outlet of a discharge passage in a discharge casing so as to be perpendicular to the flow direction of the gas at the outlet. In addition, at least one obstacle plate is disposed on the downstream side of the auxiliary demister.
