The hybrid permanent magnet rotor 3 includes a rotor core 3.1, first permanent magnets 3.2, second permanent magnets 3.3 and V-shaped magnetic barriers 3.4. The rotor core 3.1 is disposed outside the non-magnetizer rotating shaft. The V-shaped magnetic barriers 3.4 are disposed inside the rotor core 3.1. The V-shaped magnetic barriers 3.4 with openings facing outwards are equally distributed in a circumferential direction of the rotor core 3.1. A thickness of a bottom of the V-shaped magnetic barrier 3.4 is greater than a thickness of a side surface. The thicker bottom is used to effectively prevent the flux leakage path of neodymium-iron-boron, and the two narrower sides are used to guide the permanent magnet flux, so that part of the permanent magnet flux at the bottom of the neodymium-iron-boron can pass through the magnetic barrier and flow to the air gap through the aluminum-nickel-cobalt permanent magnet, thereby stabilizing the operating point of the aluminum-nickel-cobalt permanent magnet. The rotor core 3.1 is provided with air slots 3.6 with a straight-line cross section, the number of which is twice the number of the V-shaped magnetic barriers 3.4. The first permanent magnets 3.2 and the second permanent magnets 3.3 also with a straight-line cross section are respectively disposed in the air slots 3.6. A gap 3.5 is provided between the first permanent magnet 3.2 and the air slot 3.6, and the gap 3.5 is located on a side of the first permanent magnet 3.2 away from the rotating shaft, which can reduce the leakage flux on the two ends of the first permanent magnet 3.2. The numbers of the first permanent magnets 3.2 and the second permanent magnets 3.3 are the same as the number of the V-shaped magnetic barriers 3.4. In this embodiment, the numbers of the V-shaped magnetic barriers 3.4, the first permanent magnets 3.2 and the second permanent magnets 3.3 are each four, and the number of the air slots 3.6 is eight. The first permanent magnet 3.2 is a neodymium-iron-boron permanent magnet, which is disposed in the opening of the V-shaped magnetic barrier 3.4. A symmetry axis of the cross section of the V-shaped magnetic barrier 3.4 coincides with a length-direction symmetry axis of the cross section of the first permanent magnet 3.2. The first permanent magnet 3.2 is disposed with a length direction of its cross section in a radial direction of the circumference of the rotor core 3.1, the first permanent magnet 3.2 is magnetized in a tangential direction of the circumference of the rotor core 3.1, and magnetizing directions of the adjacent first permanent magnets 3.2 are opposite. The second permanent magnet 3.3 is an aluminum-nickel-cobalt permanent magnet, which is disposed between the two adjacent V-shaped magnetic barriers 3.4. The side surface of the V-shaped magnetic barrier 3.4 is perpendicular to a length-direction symmetry axis of the cross section of the second permanent magnet 3.3. The second permanent magnet 3.3 is disposed with a length direction of its cross section in a tangential direction of the circumference of the rotor core 3.1, the second permanent magnet 3.3 is magnetized in a radial direction of the circumference of the rotor core 3.1, and magnetizing directions of the adjacent second permanent magnets 3.3 are opposite.
