Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, to the technical scheme in the utility model embodiment
It is clearly and completely described, it is clear that described embodiment is only a part of embodiment of the utility model, without
It is whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making creation
Property work under the premise of the every other embodiment that is obtained, belong to the scope of the utility model protection.
As shown in figure 1, with reference to Fig. 4, piecemeal rotor of the present utility model, it includes bobbin winder bracket 1 and piecemeal rotor iron
Core 2.
Bobbin winder bracket 1, fixed multiple piecemeal rotor cores 2 and and motor connection.
Piecemeal rotor core 2, fixed for including bobbin winder bracket 1 after wound around coil.As shown in Fig. 2 it includes preceding catch 21, centre
Connector 22 and rear catch 23, the both ends of intermediate connector 22 connect preceding catch 21 and rear catch 23 respectively, during coiling is wrapped in
Between it is on connector 22 and spacing by preceding catch 21 and rear catch 23.Specifically, the bobbin winder bracket 1 includes middle annulus 13,
And the connecting portion 14 of surrounding, the preceding outer wall of catch 21 is parallel with the rear inwall of connecting portion 14 and is bonded to each other.
