Connection process of motor stator winding joints and casting mold components

Abstract

The invention discloses a connection process of motor stator winding joints, comprising the following steps: 10) customizing the casting mold assembly, the casting mold assembly includes a mold cavity, a casting solution cavity and a casting solution channel between them; 20) after the customization is completed , put the winding joints of the motor into the mold cavity; 30) control the casting solution channel to communicate with the casting solution cavity; . In the present invention, the winding joints are connected through the above-mentioned casting connection process. Compared with the welding process connection in the prior art, the connection process of the present invention can significantly improve the reliability and consistency of the winding joint connection, thereby improving the reliability of the motor. sex and longevity. At the same time, by customizing suitable casting mold components, it is also possible to simultaneously connect the winding joints 411 , thereby greatly reducing working time and improving production efficiency. At the same time, the invention also discloses a casting mold assembly.

Description

Technical field [0001] The present invention relates to the field of motor manufacturing techniques, and more particularly to a connection process and a cast mold assembly of a motor stator winding joint. Background technique [0002] The motor includes a stator and a rotor, and the fixed portion fixed in both is a stator, and the rotating portion is a rotor. After power-on, the stator generates a rotating magnetic field, rotating in the rotating magnetic field, cutting the magnetic line generating current, thereby completing energy conversion. Among them, the stator includes a stator core, a stator winding, and a base, and the stator winding refers to a winding coil mounted to the stator, i.e., a copper wire that is bypassing the stator. [0003] At present, the motor stator windings of high-power electric vehicles have tended to use flat copper wires, and multiple flat copper wires are connected in accordance with the first tail, thereby forming a whole. Typically, the winding ...

Problems solved by technology

[0004] However, due to the large number of winding joints evenly distributed in the circumferential direction, manual welding is difficult to ensure the consistency and reliability of welding quality, and the operation time is long, and the production efficiency is low; although automatic welding can maintain the winding joints after welding to a certain extent However, it is difficult to guarantee the reliability of the welding quality. At the same time, due to the size and space constraints of the weldment, the cost of automatic welding is high, and the assembly requirements are also strict.
