AI Technical Summary

Technical Problem

Existing brushless motor shaft precision testing equipment cannot simultaneously measure concentricity and circular runout, resulting in high measurement costs.

Method used

A brushless motor shaft precision testing machine was designed. Combining a slide bar, displacement sensor, pointer and scale, it can realize multiple measurements of shaft length, diameter, concentricity and circular runout. The locking component improves the stability of the slide bar and the roller reduces friction.

Benefits of technology

It enables the same equipment to perform multiple precision measurements, reducing the factory's measurement costs and equipment wear errors.
