Winding process of stator interphase coil

Abstract

The invention, which belongs to the production technology of the motor stator, especially relates to a process for stator interphase coil winding. On the basis of cladding and clamping of an enameled wire by a feeding and cutting mechanism and pre rotation of a winding nozzle, problems of long length of the stator interphase bridging wire and unstable shape can be solved; and thus the length of the bridging wire is reduced and the shapes of the bridging wires are uniform. Therefore, the forming quality of the stator interphase bridging wire is improved and the length of the bridging wire is shortened.

Description

technical field [0001] The invention belongs to the production process of the motor stator, in particular to a process for coil winding between phases of the stator. Background technique [0002] The stator is an important part of the motor. There are many occasions where the motor is used in industrial products, and many electrical products are used as the driving power source. [0003] When the existing winding machine is working, when the winding machine winds the first phase coil and performs phase change, the clamping mechanism moves to the designated station, and the clamping mechanism clamps the enameled wire and sends it to the second designated station , during this action, the enameled wire located between the clamping mechanism and the winding mold will be pushed forward by the clamping mechanism, and the enameled wire may form a fold or a slack at the end of the first phase coil. When the clamping wire After the mechanism is sent to the second designated station...

Problems solved by technology

[0003] When the existing winding machine is working, when the winding machine winds the first phase coil and performs phase change, the clamping mechanism moves to the designated station, and the clamping mechanism clamps the enameled wire and sends it to the second designated station , during this action, the enameled wire located between the clamping mechanism and the winding mold will be pushed forward by the clamping mechanism, and the enameled wire may form a fold or a slack at the end of the first phase coil. When the clamping wire After the mechanism is sent to the second designated station, the winding nozzle starts to work, and the second phase coil is wound. After the winding machine is finished, there must be a fold between the first phase coil and the second phase coil. Shaped or loose bridge wires cause the bridge wires between the phase coils to be long, resulting in waste of enameled wires. When the coils are embedded in the stator, the wires of the coils at the end of the stator are chaotic, which affects the subsequent stator. The coil at the end is reshaped, and the quality of the coil at the end of the stator obtained by reshaping cannot meet the requirements
