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.
