AI Technical Summary

Problems solved by technology

The traditional method is to establish different experimental platforms for different motor systems, and then conduct experiments on the established experimental platforms. The disadvantage of this method is that the universality of the motor experimental platforms is poor, so the experimental devices have single functions and low cost performance.

So far, there is no report on the invention of an experimental device suitable for various control strategies of various motors
