摘要： A brushless motor has a stator and a rotor rotatably installed inside of the stator. The stator includes a stator core with teeth protruding inwardly and windings wound on the teeth. The rotor includes a shaft, a rotor core fixed on the shaft, and a ring magnet fixed to the circumferential outer surface of the rotor core. The magnet includes a plurality of magnetic poles radially magnetized so that north poles and south poles are arranged alternately in the circumferential direction. Boundary lines between magnetic poles are skewed by an angle relative to an axis of the shaft.
