specific Embodiment approach 1
[0031] Specific implementation mode one: the following combination Figure 1 to Figure 4 This embodiment is described. The three-stage variable magnetic circuit series-parallel adjustable flux motor described in this embodiment includes a stator core 1, a stator winding 2, a rotor core 3 and a rotating shaft 4; the rotor core 3 is fixed on the rotating shaft 4, and Located inside the stator core 1, the armature winding 2 is arranged on the stator core 1;
[0032] Also includes series-parallel adjustable magnetic poles, the series-parallel adjustable magnetic poles include No. 1 high-coercivity permanent magnet 7, No. 1 low-coercivity permanent magnet 8, No. 2 low-coercivity permanent magnet 9 and No. 2 high-coercivity permanent magnet Coercive permanent magnet 10;
[0033]A V-shaped permanent magnet slot 5 and a flat-shaped permanent magnet slot 6 are arranged under each pole of the rotor core 3, and a flat-shaped permanent magnet slot 6 is arranged in the opening of the V-sh...
specific Embodiment approach 2
[0048] Specific embodiment two: This embodiment will further explain embodiment one, No. 1 high-coercivity permanent magnet 7, No. 1 low-coercivity permanent magnet 8, No. 2 low-coercivity permanent magnet 9 and No. 2 high-coercivity permanent magnet The setting mode of force permanent magnet 10:
[0049] The No. 1 high-coercive force permanent magnet 7 and the No. 2 high-coercive force permanent magnet 10 are both integral permanent magnets, or consist of multiple permanent magnets along the axial direction.
[0050] The No. 1 low-coercive force permanent magnet 8 and the No. 2 low-coercive force permanent magnet 9 are of two-stage split structure or integral structure, and adopt a single permanent magnet or consist of multiple permanent magnets along the axial direction. The No. 1 low-coercivity permanent magnet 8 and the No. 2 low-coercivity permanent magnet 9 can be two independent permanent magnets, or two parts of a whole permanent magnet.
specific Embodiment approach 3
[0051] Embodiment 3: In this embodiment, Embodiment 1 is further explained. A magnetic bridge is set at the symmetry axis of the V-shaped permanent magnet slot 5 under each pole, and between the outer magnetic pole and the circumference of the rotor.
