Motor manufacturers will conduct spot checks on each batch of newly introduced Copper Winding Wire and enter the production line only when the breakdown voltage, film continuity, elongation, resilience, flexibility and other indicators meet the requirements.

In the manufacturing process of copper winding wires, there is a process called annealing. Its purpose is to make the metal wire harden due to lattice change during die drawing. After heating at a specified temperature, the molecular lattices can be rearranged to restore the softness required by the process. At the same time, lubricant and oil stains remained on the surface of the wire during the drawing process can be cleaned, so that the wire is easy to paint and the quality of enameled wires is guaranteed. More importantly, the annealing process ensures proper flexibility and elongation of the copper winding wire during use, which is beneficial to improving the conductivity.

At present, most manufacturers adopt full-automatic production lines and carry out continuous annealing before the enameling machine is painted, which not only can achieve the purpose of softening and degreasing but also the annealed lines are straight and directly enter the enameling device.

Annealing of copper winding wire is a different material and heat treatment process, but its connotation is more complex.

1. As the main material of the motor, it occupies a high proportion in the material cost, and its electrical and mechanical performance indexes have an important impact on motor performance;

2. Annealing process is mechanical, chemical and heat transfer theory in manufacturing process.

3. The suitability of its electrical and mechanical properties to the use process is the annealing process in its manufacturing process objective.
