The Development Of Test Equipment For Motor Driver

The test equipment for motor driver is to monitor the performance and working status of the motor driver, it is a test platform to detect the abnormal of the motor driver. It is designed to help with the Product developers and testers for system testing. The test results will be dynamically displayed on the LCD screen. When Abnormalities occurs, the buzzer will alarm. The equipment will test the voltage of the motor driver, the current of the motor driver, the drive signal output, the protection of Abnormalities, etc. We can press the key button to select the content of the test, after the test, the test equipment will display the collected data on the LCD screen, and indicate the correctness of the data.Motor drive test system is mainly used for product testing of the motor drives, to ensure the accuracy and reliability of the motor drives, in order to avoid welding errors and component damage that appeared in the production process, which will affect the normal operation of the motor drive. The system consist control module and test modules, the test modules include one lower arm test and three arm tests, each test requires a separate power supply and a separate test, to prevent interference. The control module send the beginning and ending commands to a test control module to stat the test, and receive test data then show the result analyzed by the data. The test modules will start test after receiving specific instructions, after the test, the data is uploaded to the control module.The system selected (ST)'s STM32 family of microcontrollers to constitute the core of the drive test equipment. The software of the system we use IAR EWARM to achieve system control and testing functions.So far, the test equipment for motor driver has been set up and it is already in use, the test equipment realize of the basic the required content of the test. The system has good prospects, if it is successfully applied to the wide range of production, not only can greatly improve the automation of motor drive test, reduce the labor intensity of the test staff, but also save a lot of money for the enterprise.
