The stator of the rotating electric machine also includes a plurality of terminal blocks 109, and each terminal block 109 is respectively fixed to the outer side 105c of each stator tooth 104b, which is used as the wire connection of the coil. In some embodiments of the present invention, the center 109a of the terminal base 109 is not located at the center 105d of the outer side 105c of the stator tooth 104b (this number is not seen in Figure 5). In some embodiments of the present invention, the center 109a of the terminal base 109 is located between the center 105d and the edge 105e of the outer side 105c of the stator single tooth 104b. In some embodiments of the present invention, the terminal base 109 and the upper winding frame 108 are an integrally formed insulating plastic body.

Each terminal block 109 is used for inserting a terminal 115 to electrically connect the end 113 a of the coil 113. The exposed end of the terminal 115 is connected to the connecting conductor 117, and the connection forms the required stator winding. The connecting conductor 117 is arranged between the rotor accommodating space 120 and the terminal bases 109 to avoid interference with the rotation of the rotor. The slanted arrangement of the first slot 109b of the terminal block 109 is also beneficial to widen the wiring area of the connecting conductor 117. In addition, the arrangement of the terminal base 109 deviating from the outer center 105d also facilitates the advantage of shortening the reserved length of the coil 113. In some embodiments of the present invention, the connecting conductor 117 may be a flexible wire or a sheet metal part.

Please refer to FIGS. 8 and 9 at the same time, which show enlarged schematic diagrams of the terminal inserted into the corresponding terminal base of the embodiment of the present invention. The terminal base 109 has a first wire slot 109b, and each terminal 115 has a second wire slot 115a. When each terminal 115 is inserted into each corresponding terminal block 109, the second wire groove 115a and the first wire groove 109b are aligned with each other to be joined to clamp the one end 113a of the coil 113, and the terminal 115 is inserted into the terminal block 109 at the same time It has the function of destroying the insulating outer layer of the clamped coil 113, so that the coil 113 and the terminal 115 can be electrically connected. The side of each terminal 115 has a hook 115b design, so that the terminal 115 is inserted into each corresponding terminal base 109 to achieve the purpose of being fastened and not easy to fall off.

In the stator of the rotating electric machine of the present invention, the wire slot of the terminal block is skewed, and the end of the coil that it clamps also has a skew angle, which increases the insulation distance between the end of the coil and the motor frame and avoids the end of the coil. Too close to the metal frame produces high-voltage arc discharge, and at the same time increases the distance between the connection position of the terminal block and the rotor housing space, increases the wiring space, and avoids unnecessary interference when the rotor rotates.
