Problems solved by technology

When the stator of this structure is welded with the pins, it is necessary to prevent tin slag from falling into the winding 3 through human operation awareness and self-inspection and mutual inspection. If the tin slag falls into the winding 3, it will cause poor withstand voltage between stator turns
However, due to the unreliability of human operation and inspection, the performance of the stator cannot be guaranteed, and this structure is not conducive to automatic production

Embodiment Construction

[0029] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

[0030] like Figure 4 to Figure 8 As shown, according to the embodiment of the present invention, the stator includes a stator body and an end protector 20 fixedly connected to one end of the stator body and covering the windings 11 of the stator body. By arranging the end protector 20 at the end of the stator body, the end of the winding 11 of the stator body can be closed, so as to protect the end of the stator winding 11 during welding, prevent tin dross from falling into the winding 11, and ensure the quality of the stator. Improve the ability to adapt to automated production. The stator solves the hidden danger of electrical safety caused by "fried tin" and foreign objects falling into the winding 11 of the stator winding of the motor, reduces process defects, realizes automatic production, and improves production efficienc...

Abstract

The invention provides a stator and a motor with the same. The stator includes a stator body and an end protector which is fixedly connected to one end of the stator body and covers the winding of thestator body. The problem that the inter-turn withstand voltage of the stator is poor due to the tin slag falling into the winding is avoided.

Description

technical field [0001] The present invention relates to the field of electric equipment, in particular, to a stator and a motor having the same. Background technique [0002] With the wide application of permanent magnet brushless DC motors, the quality problem of the motor has become more and more prominent, especially the electrical safety problem, which is not allowed to occur. The windings of the permanent magnet brushless DC motor are arranged on the stator, and the head and tail ends of the three-phase stator windings of the existing motor are welded with U, V, W and O pins. This process is done manually online. like Figure 1 to Figure 3 As shown, in the stator of the motor in the prior art, the head end 1 of the winding is connected with pins U, V and W respectively, the tail end 2 of the winding is connected with the pin O, the winding 3 is wound on the skeleton 4, and the iron core 5 is fixed on skeleton 4. The stator of this structure prevents tin dross from fal...
