specific Embodiment approach 1
[0007] Specific implementation mode 1. Combination figure 1 and figure 2 ,as well as Figure 17 and Figure 18 Describe this embodiment, this embodiment is made up of casing 1, primary and secondary 6; Secondary 6 is made up of permanent magnet array and yoke plate 61; Primary is made up of several phase units 2; The phase unit core 3 and the phase unit winding 4 are composed; each phase unit core 3 is composed of 2k core units 5 and has a tooth hole 71, and the tooth hole 71 is composed of 2k core units 5 tooth slots 72 Formed by stacking, each core unit 5 is composed of two teeth and a yoke segment; the two teeth are arranged along the horizontal direction of the cross section, and a yoke segment is connected between the two teeth; 2k core units 5 are arranged in the casing 1 at equal intervals in sequence along the moving direction; the coil 41 is wound into a phase unit winding 4 through the tooth hole 71 of the phase unit core 3; when the motor is an m-phase motor, t...
specific Embodiment approach 2
[0008] Specific embodiment two, combine Figure 3 to Figure 6 Describe this embodiment. The first difference between this embodiment and the specific embodiment is that each core unit 5 in the phase unit core 3 is composed of a long tooth 51, a short tooth 52, a high-level yoke segment 53, a low The horizontal yoke section 54 and a vertical yoke section 55 are composed; the long teeth 51 and the short teeth 52 are arranged along the horizontal direction of the cross section, and the long teeth 51 and the short teeth 52 are sequentially connected with high The horizontal yoke section 53, the vertical yoke section 55 and the low horizontal yoke section 54, the side root of the long tooth 51 is connected to the side of one end of the high horizontal yoke section 53, and the high horizontal yoke The other side of the section 53 is connected to the root of one side of the vertical yoke section 55, and the other side of the vertical yoke section 55 is connected to one end of the low...
specific Embodiment approach 3
[0009] Specific embodiment three, combine image 3 and Figure 4 Describe this embodiment, the difference between this embodiment and the specific embodiment is that the coil 41 is wound circularly on the upper part of the long tooth 51 or on the high horizontal yoke segment 53 or the vertical yoke segment 55 through the two tooth holes 71 to form a Phase phase unit winding 4. Other compositions and connection methods are the same as those in Embodiment 1.
