specific Embodiment approach 1
[0007] Specific implementation mode 1. Combination Figure 1 to Figure 8 ,as well as Figure 19 Describe this embodiment, this embodiment it is made up of casing 1, stator and rotor 6; Rotor is made up of permanent magnet array and rotor yoke 61; Stator is made up of several phase units 2; Each phase unit 2 is made up of several phase units core 3 and phase armature winding 4; each phase unit core 3 is composed of k core units 5, and each core unit 5 is composed of n teeth and a yoke; the n teeth are arranged axially, so A magnetic yoke is connected between the n teeth mentioned above; k core units 5 are arranged at equal intervals in the casing 1 along the circumferential direction, and the k core units 5 are stacked and arranged in the axial direction to form the tooth holes 71 of the phase unit core 3 and combined tooth slot 72; coil 41 passes through tooth hole 71 of phase unit core 3 and winds into a phase phase armature winding 4; rotor 6 is composed of permanent magnet...
specific Embodiment approach 2
[0008] Specific embodiment two, combine Figure 1 to Figure 12 Describe this embodiment, the difference between this embodiment and the specific embodiment is that each core unit 5 in the phase unit core 3 is an iron core unit with a tooth groove, and the iron core unit with a tooth groove is composed of a long tooth 51, A short tooth 52, a short vertical yoke segment 53, a long vertical yoke segment 54 and a horizontal yoke segment 55; the long teeth 51 and the short teeth 52 are arranged axially along the cross section, and the A short vertical yoke segment 53, a horizontal yoke segment 55 and a long vertical yoke segment 54 are connected in sequence between the long teeth 51 and the short teeth 52, and the upper part of the side of the long teeth 51 is connected to the short vertical yoke segment. 53 is connected to the lower side of one side, the upper side of the other side of the short vertical yoke section 53 is connected to one end of the horizontal yoke section 55, an...
specific Embodiment approach 3
[0009] Specific embodiment three, combine Figure 16 to Figure 18 This embodiment is described. The difference between this embodiment and the second embodiment is that each core unit 5 in the phase unit core 3 is formed by combining two core units with one cogging in the axial direction and has two coggings. The core unit of the core unit, the core unit with two cogs has two combined structures, one combined structure is that two long tooth sides of two core units with one cog are combined and connected to form a unit with two A core unit with two slots, and another combined structure is that two short tooth flanks of two core units with one slot are merged and connected to form a core unit with two slots, which is the two described two slots The core unit with one tooth slot is connected by two long tooth sides or by two short tooth sides; any one of the two adjacent core units 5 in the phase unit core 3 has two tooth slots One of the core units with one cogging is turned o...
