Embodiment 1
[0031] In one or more embodiments, a hybrid excitation wound rotor is disclosed, which is applied to a wound permanent magnet motor. The rotor includes a rotating shaft 8, a rotor core 6 fixed on the rotating shaft 8, and a rotor core 6 on the rotor core 6. Winding coils, and permanent magnets 7 installed at the ends of the salient poles of the rotor. A set of winding coils is installed on each salient pole to generate rotor magnetomotive force. A piece of tile-shaped permanent magnet 7 is installed along the opposite side of the rotation direction of the motor rotor on the geometric center line of each salient pole end, and the permanent magnet 7 makes the rotor asymmetric. The iron core of the rotor part is formed by axially laminating cold-rolled silicon steel sheets. The winding on the rotor core 6 is connected to the DC power supply through the brush slip ring, and the current passes through the winding to generate the rotor magnetomotive force.

Embodiment 2
[0040]In one or more embodiments, a hybrid excitation wound synchronous motor is disclosed, referring to figure 1 , The high-performance hybrid excitation wound synchronous motor has a stator part and a rotor part inside the casing.
[0041] Wherein, the rotor part adopts the rotor part structure disclosed in the first embodiment.
[0042] The stator part includes: stator core 1 and stator winding 2. The stator core 1 is formed by laminating silicon steel sheets in the direction of the rotating shaft 8. The silicon steel sheets are thin plates made by adding silicon to iron to reduce eddy current loss. The stator core 1 is cylindrical and extends in the direction of the rotating shaft 8 of the rotating shaft 8 . The stator slots are arranged at equal intervals along the circumferential direction on the inner periphery of the stator, and extend from the stator core 1 side to the rotating shaft 8 in a convex shape. In this embodiment, 27 stator slots are provided, and three-p...
