| titleOfInvention | Embedded permanent magnet motor rotor and permanent magnet motor |
| abstract | The invention discloses an embedded permanent magnet motor rotor and a permanent magnet motor, which comprise an inner rotor iron core, wherein the inner rotor iron core and a magnetic yoke iron core are provided with corresponding symmetrical polygons or asymmetrical polygons or special shapes, are opposite to and spaced at a certain distance, and are isolated by an insulating material; the magnetic yoke iron core is provided with a plurality of arc sections at the outer edge opposite to the permanent magnet, a main arc section in the middle and auxiliary arc sections at two sides; the outer side of the auxiliary arc section is far away from the direction of the central line and extends towards the direction of the q axis, the adjacent auxiliary arc sections are connected, the two ends of the main arc section are respectively connected with the auxiliary arc sections, and the main arc section and the auxiliary arc sections form the radian of the peak tops of the sine waves. The invention has novel and reasonable structure, reduces the electromagnetic torque pulsation, provides an ultra-silent permanent magnet motor, reduces the voltage of a motor shaft, reduces the electric corrosion of high-voltage static electricity to a bearing, and prolongs the service life of the motor. |
