AI Technical Summary

Technical Problem

Traditional motor housings require customized molds, resulting in high costs when producing different lengths and sizes. Furthermore, overall replacement and maintenance costs are high, and the entire unit must be replaced if only a part is damaged.

Method used

The motor housing adopts a modular structure, which is connected by a combination of housing and limiting components, allowing for axial dimension adjustment. In case of partial damage, only the corresponding module needs to be replaced. Combined with labyrinth seals and dovetail groove connections, it improves heat dissipation efficiency and dust and water resistance.

Benefits of technology

It enables the production of motor housings with different axial dimensions without the need for new molds, reducing manufacturing and maintenance costs, improving heat dissipation efficiency and protection performance, and making it suitable for high temperature and high pressure environments.
