The wiring structure of distributed coil motor 100 according to an alternative embodiment of the present invention is indicated in fig. 2.

Referring to fig. 1 and 2, the bus bar insulating bobbin 30 is mounted to the stator winding 20. The protector 40 is mounted on the flat cable insulating skeleton 30 and electrically connected to the first terminal 21.

Alternatively, in some embodiments of the present invention, at least a portion of the protector 40 may be received in the flat cable insulating skeleton 30, so that the flat cable insulating skeleton 30 not only serves as a mounting carrier for the protector 40, but also protects the protector 40. Further, the protector 40 may pierce the first terminal 21 when being received into the flat cable insulating bobbin 30 to achieve electrical connection with the first terminal 21. Thus, the protector can be connected to the first terminal 21 while the protector 40 is mounted, so that the wiring process of the stator winding 20 and the protector 40 can be simplified, the production efficiency can be improved, the manufacturability of the stator can be improved, and the production cost can be reduced.

Here, piercing the first terminal 21 means piercing an insulating layer of a surface of the first terminal 21 so that an inner conductor of the first terminal 21 is exposed to achieve a contact connection with the protector 40.

The number of the limiting grooves 322 may be set according to the number of the first terminals 21, for example, the number of the limiting grooves 322 is the same as the number of the first terminals 21, and corresponds to one another.
