| titleOfInvention | A stator-rotor segmented permanent magnet motor |
| abstract | The invention proposes a stator-rotor segmented permanent magnet motor, which belongs to the technical field of automotive electrical appliances, and includes permanent magnets, motor shafts, segmented rotor cores, non-magnetic rotor sleeves, segmented stator cores and armature windings; quantity Each of the 6X segmented stator cores is made of 2Y+1 T-shaped silicon steel sheets laminated, and the polar arc angles of each silicon steel sheet are arranged in equal difference; the segmented rotor cores are respectively embedded in 4X In the non-magnetic rotor rotor sleeve with fan-shaped grooves, the segmented rotor core is fan-shaped, and there is a cutting line segment at the intersection of the fan-shaped two sides of the segmented rotor core and the fan-shaped arc, and the cutting line segment and the two fan-shaped side clips The angle is greater than 120°, and the arc lengths of each fan-shaped silicon steel sheet forming the segmented rotor core are arranged in equal differences; the advantage of the present invention is that the shapes of the segmented stator core and the segmented rotor core can be eliminated by mutual cooperation. The unbalanced electromagnetic force reduces the cogging torque, and can also weaken the noise, vibration and EMF harmonics generated during normal operation of the motor. |
