Abstract:

on the basis of the method and substance of the motor factory test and type-test, this article put forward a variable frequency and energy-feedback typed power supply experimental-testing solution with the twin inverter shared the same DC bus; the data-testing system was the effective combination of hardware system which contains IPC,DAQ and sensors and software system including PC graphics, UI, and data processing and analysis APP, it can succeed in testing and processing the input/output data automatically which improved the motor's testing efficiency and precision. The experimental-testing solution is successfully applied to Subject platform of electrical and electrical engineering of Hunan institute of electrical engineering, The application results showed that the test system is easy to operate, safe and reliable, and realizes the energy efficiency and digitization.
