Embodiment Construction
[0032] The present invention is a flux-switching motor with rotor flux modulation. The specific implementation of the present invention will be described in detail below by taking a three-phase rotor flux-modulation flux switching motor as an example.
[0033] The rotor magnetic flux switching motor provided by the present invention includes a stator and a rotor, both of which adopt a salient pole structure; the rotor includes: a rotor magnetic pole module 1, a magnetic isolation block 4, a magnetic modulation block 5 and a shaft 6. The rotor pole module 1 includes two rotor teeth 2 and a permanent magnet 3, the permanent magnet 3 is embedded between the two rotor teeth 2, the permanent magnet 3 is magnetized tangentially, and is adjacent to the permanent magnet 3 The magnetization direction is the same; the magnetic spacer 4 is embedded between the adjacent rotor pole modules 1,
[0034] The rotor magnetic pole module 1 and the magnetic isolation block 4 jointly form an annul...
