ROTOR AND MOTOR HAVING ROTOR

摘要

A rotor and a motor having the rotor. The rotor comprises a rotating shaft (1), a rotor magnetic conduction yoke (2), a plurality of first permanent magnet groups (3) and a plurality of second permanent magnet groups (4), wherein the plurality of first permanent magnet groups (3) and the plurality of second permanent magnet groups (4) are equidistantly and alternately distributed at intervals along the circumferential direction of the rotor magnetic conduction yoke (2); and projections of the first permanent magnet groups (3) and the second permanent magnet groups (4) on a plane vertical to the rotating shaft (1) are adjacent and are in edge superposition. The rotor is able to reduce torque pulsation caused by electromagnetic factors and increase torque to work outwards, thereby obtaining the beneficial effects of increasing power consuming efficiency of the motor and saving energy.
