Connection process for motor stator winding

Abstract

The invention provides a connection process for a motor stator winding. The connection process comprises the following steps of: 1, splicing splits of the stator winding to form a motor stator and making lead-in position and lead-out position of each coil consistent; 2, sleeving a motor phase wire connection ring and a winding connection ring; 3, dip soldering, namely, placing the stator on a tray, making the lead-out end of the stator winding face down, automatically positioning the tray when the tray moves to the position of a tinpan on the assembly line, and performing dip soldering on the lead-out end of the winding on the tinpan; and 4, welding a motor wire. In the invention, the stator winding is welded in a mode of integral dip welding by using a connection ring instead of a multi-point manual welding mode in the prior art, so vertically crossed welding points on a wire rod are avoided, all welding spots can be welded at one time, and then the production efficiency and welding quality are greatly improved, and the usability of the motor can be better guaranteed.

Description

technical field [0001] The invention relates to the field of motor manufacturing, in particular to a motor stator winding connection process. Background technique [0002] In the motor application system, in addition to selecting a suitable motor type according to the motor speed, efficiency, power and other parameters required by the system, it is also hoped that the size of the motor is small, and the heavy and bulky motor is prone to loud noise, noise, and noise during operation. Additional vibration is big and the problem of inconvenient operation. [0003] At present, the connection of motor wires is mostly that each phase wire is branched from the motor bus and connected to the corresponding winding, so it is inevitable that the connecting wires will cross and overlap up and down, and it is easy to cause wrong connection or poor welding during welding. After the connecting wire is welded, it must be wrapped and fixed with a strap and pressed tightly to limit the heigh...

Problems solved by technology

[0005] Due to the complex winding process, low efficiency and high cost of the integral stator core, it has been gradually converted to a block-type stator, that is, electromagnetic coils are wound on the teeth of the block-type iron core, and then each block stator is spliced ​​at the yoke. Integral stator

Due to the large number of winding wire ends, especially when using relatively thick and hard flat copper wires, it is necessary to reshape each welding point first, then weld the wire ends to be connected in turn, and finally add sleeves and straps for insulation and fixing, and the entire connection The process takes about 2 hours, and the production efficiency is low
