To provide a motor and a compressor therewith, capable of securing a fluid passage of lubrication oil as usual and attaining reduction in oscillation and noises.
This motor is provided with a stator having a straight line cut surface at a circular outer periphery surface of a stator iron core and an armature winding in slots by forming the plurality of slots in the stator iron core, and a rotor rotatably supported at an inner periphery side of the stator with a prescribed gap. The linear cut surface of the stator iron core is staggered by arbitrary laminated thickness in an axial direction in a circumferential direction to eliminate local magnetic saturation of a core back by unifying a core back area of the stator iron core in the axial direction and the circumferential direction, and to improve a cogging torque and an induction voltage waveform distortion ratio by securing the fluid passage of the lubrication oil as usual, thus reducing oscillation and noises.
