Problems solved by technology

[0003] Traditional manual control instruments and motor measurement methods that rely entirely on manual visual readings still exist in many motor manufacturers in my country. Not only are the work efficiency low, the labor intensity of the workers is high, and there are also indeterminate measurement errors.
The traditional manual operation of motor parameter measurement is not suitable for the rapidly developing industry in terms of quantity or quality
