What kind of heat treatment does the DC motor use? This is the relevant question we are going to talk about in this issue. The answer to this question is in the following explanation:
1. Stress removal annealing treatment: the purpose is to eliminate casting force and improve mechanical properties and machining performance.
2. Graphitization annealing: If the cross-section size of the DC motor is quite different, it is easy to form a white hole in the thin section, so graphitization annealing must be carried out, and the purpose is to eliminate the white hole.
3. Other materials: There are also aluminum alloy DC motors. The heat treatment performed is similar to that of cast iron and the purpose is similar. However, important aluminum alloy parts need solution treatment and aging in order to improve the mechanical properties.
4. Homogenization annealing: In order to improve the mechanical properties of the more important DC motors or DC motors of other cast iron materials, homogenization annealing is required, because a lot of chemical composition segregation is formed during the casting process, and the purpose is to uniformize the structure and ensure the mechanics of each section Consistent performance, improve mechanical properties.
