The rings can be spaced apart from each other along the inner periphery of the yoke portion 111 , so that the motor rotor (not shown) is relatively arranged in the plurality of magnetic poles 112 for induction.

As shown in Figure 6, a plurality of coil groups 2 are wound on the core frame 1, and the plurality of coil groups 2 include first phase coil groups 21, second phase coil groups 22 and The third phase coil set 23 .

Among them, the first phase coil group 21, the second phase coil group 22 and the third phase coil group 23 can respectively correspond to U-phase coils, V-phase coils and W-phase coils, so as to form a phase change of three-phase AC, thereby interactively generating S The pole and the N pole induce the rotor (not shown) and drive it to rotate.

As shown in Figures 1 to 6, each conductive ring 31 is made of a ring body made of high-conductivity materials such as copper, silver, and gold. The plurality of conductive loops 31 include a first conductive loop 311 , a second conductive loop 312 , a third conductive loop 313 and a fourth conductive loop 314 arranged concentrically from inside to outside.

As shown in Figures 1 to 6, the insulator 32 is coated on the outside of a plurality of conductive rings 31 by plastic injection molding. The coil sets 2 are welded to the conductive loops 31 through the hollow openings 321 , so that the coil sets 2 are electrically connected to the conductive loops 31 through the hollow openings 321 .

The details are as follows, the plurality of hollow openings 321 include a plurality of first hollow openings 322 configured only for the first conductive ring 311, a plurality of second hollow openings 323 configured only for the second conductive ring 312, and only corresponding to the third conductive ring 312.
