Embodiment Construction
[0019] Such as figure 1 As shown, in the centralized winding motor where the winding is directly performed at the position of the tooth part 1 of the existing motor, since the stator core is an integral structure, a space 2 should be reserved during the winding process of the motor. Since this space cannot be used, the affect the motor efficiency.
[0020] Figure 2A It shows the schematic diagram of the existing split iron core. At present, there are the following problems: a certain distance is reserved between adjacent teeth at the slot structure. At this time, due to the insulation distance of the opening, a part of the slot space 11 cannot be wound around. Wire.
[0021] Figure 2B It shows another schematic diagram of the existing split iron core. At present, there are the following problems: due to the contact between adjacent teeth, part of the stator and rotor magnetic flux passes through the contact part 12 to form a closed loop without connecting with the stator ...
