titleOfInvention | Permanent magnet brushless motor rotor and motor |
abstract | The utility model discloses a permanent magnet brushless motor rotor and a motor, wherein the rotor comprises a rotor iron core and rectangular magnetic steel, and a plurality of magnetic steel slots which are axially communicated are arranged on the rotor iron core; the magnetic steel slots are uniformly and symmetrically distributed along the circumference of the rotor core; the first section of each magnetic steel slot comprises an inner side edge close to the axis of the rotor core and an outer side edge far away from the axis of the rotor core, and at least one of the inner side edge and the outer side edge is in a curve shape; the first section is parallel to the axial end face of the rotor core; the magnetic steel is embedded into the magnetic steel groove. According to the utility model, at least one of the inner side and the outer side of the magnetic steel slot is designed into a curve, so that the cogging torque of the permanent magnet brushless motor can be reduced, the torque fluctuation of the permanent magnet brushless motor in operation can be effectively reduced, the vibration noise of the permanent magnet brushless motor can be further reduced, the operation stability of the permanent magnet brushless motor can be improved, the harmonic loss can be reduced, the temperature rise of the magnetic steel can be reduced, the demagnetization resistance of the magnetic steel can be improved, and the overload resistance of the motor can be improved. |
