摘要:
A rotor having permanent magnets for a brushless electromotor includes a yoke formed from a plurality of silicon steel sheets laminated together and provided along its outer periphery with even number of, at least four magnetic poles. The magnetic poles are alternately provided substantially at equal distances from a rotational axis with slots to receive the respective permanent magnets such that the sides of the permanent magnets facing a rotary shaft have the same polarity. As a result, a compact and efficient rotor is obtained, and damage to or flying off of the permanent magnets is prevented.
