Abstract

The invention relates to the technical field of permanent magnet motors, and discloses a tilting outer rotor permanent magnet motor, which includes a stator core and an outer rotor core that is annularly sleeved outside the stator core, and a plurality of magnets are installed on the outer rotor core. The outer rotor core is provided with multiple installation slots for the insertion of magnetic steel and multiple magnetic isolation holes for suppressing magnetic flux leakage. The inner wall of the outer rotor core is provided with multiple holes for weakening the motor torque fluctuation. The air-gap grooves, each installation groove is set obliquely relative to the radial direction of the outer rotor core, and each magnetic isolation hole is located between the installation groove and the stator core. In the tilted outer rotor permanent magnet motor of the present invention, the magnetic steel is inclined to change the direction of the original magnetic field, so that the d-axis inductance is smaller than the q-axis inductance, which improves the speed expansion capability of weak magnetic field and suppresses the noise during operation. The magnetic isolation hole and the air gap slot can respectively prevent magnetic flux leakage and change the air gap magnetic field, both of which increase the utilization rate of the magnetic steel, and then improve the output efficiency of the inclined outer rotor permanent magnet motor.

Description

technical field [0001] The invention relates to the technical field of permanent magnet motors, in particular to an inclined outer rotor permanent magnet motor. Background technique [0002] Permanent magnet motors have the advantages of simple structure, high power density, wide high-efficiency area, and high torque density, and have become the mainstream motor type in the market. [0003] Among them, the surface-mounted permanent magnet motor pastes the magnetic steel on the surface of the outer rotor iron core, and after the inner stator is wound and energized, the outer rotor is rotated to output kinetic energy. like figure 1 As shown, the surface-mounted permanent magnet motor 2 in the current prior art is not only low in the utilization rate of the magnet steel because the magnet steel 21 is exposed and attached, but also is easy to demagnetize, resulting in failure of the outer rotor, and the air gap magnetic field generated during rotation Approaching a square wave...
