摘要: A motor includes a shaft, a bearing for supporting the shaft rotatably, a rotor including a rotor frame to be mounted to the shaft along an axial direction of the shaft, a stator confronting an outer wall of the rotor via a space, and a washer disposed between the bearing and the rotor frame. On top of that, a step section forming a recess is provided to the rotor frame at a place where the washer confronts the rotor frame.

摘要: An electric motor is equipped with a rotor having multiple rows of slits arranged along a radial direction. A permanent magnet is buried only in some of the slits, namely the ones closest to the center of the rotor or the innermost slits, to drive the motor using both magnet torque and reluctance torque. This improves the torque output.
