Embodiment Construction

[0012] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0014] The present invention is a shaping structure proposed for a 9-slot, 3-phase motor stator using a centralized winding method, but similarly, this principle is also applicable to single-phase or other types of motor stators.

[0015] Such as Figure 1 to Figure 4 As shown, a motor stator provided by the present invention includes:

[0016] stator core;

[0017] A coil bobbin, the coil bobbin is arranged at both ends of the stator core in t...

Abstract

The invention provides a motor stator which comprises a stator iron core, a coil frame, windings, an A-phase wiring piece, a B-phase wiring piece, a C-phase wiring piece and a star point wiring piece. The coil frame is disposed at two axial ends of the stator iron core. Each winding is wound on the stator iron core and the coil frame. Each winding is provided with a wire inlet end and a wire outlet end. Each wire inlet end of the winding is electrically connected with the A-phase wiring piece, the B-phase wiring piece and the C-phase wiring piece. Each wire outlet end of the winding is electrically connected with the star point wiring piece. The invention further provides a motor with the stator. By the arrangement, wiring among motor stator windings in the prior art is avoided, the structure of outward suspension of winding guide-out wires is omitted, manufacturing efficiency of wire outlet ends of motor stator windings is increased, and an anti-fault function is achieved.

Description

technical field [0001] The invention relates to a motor stator and a motor using the same. Background technique [0002] In the prior art, a motor stator lead wire routing method, in order to achieve a high slot full rate to improve the efficiency of the motor stator, the motor stator often adopts a concentrated winding (the coil is wound on a single stator tooth). In this motor stator Among them, the stator includes a stator core, a coil bobbin and windings, the coil bobbin is assembled on the two axial end faces of the stator core, and the winding is wound on the stator core and the coil bobbin. After the winding is completed, the lead wires are drawn out from the winding and connected to their corresponding control circuit boards. The outer circumference of the coil frame of this design is designed with protrusions evenly distributed along the circumferential direction. After the lead wires are drawn out from the winding, they are lapped on the coil frame through the pro...
