| Traditional methods of detecting starter performances, such as visual observation on needle meters, usually bring us big errors and low efficiency A computer detection system of starter performances was developed, which can automatically test the performances, such as voltage, current, rotation speed, torque and so on It has the functions of automatical loading, collection and calculation of data, report printing, drawing of performance curves, data saving etc It considerably improved the test precision and efficiency The working principle, hardware and software design of the system are described in detail in this paper |
