Description

Technical Field

[0001] This utility model relates to the field of motor controller testing technology, and in particular to an automatic testing device for high-power motor controllers. Background Technology

[0002] Traditional testing systems involve powering products through tooling fixtures, with personnel connecting to and controlling various test conditions. High-power motor controllers require testing high current and voltage, posing inherent risks for manual operation. Furthermore, operator skill varies, making the system highly susceptible to human error. Additionally, no data is saved, making it impossible to track production parameters. Therefore, this system addresses the current production situation by using program-controlled testing to eliminate human error during production, achieving fully automated testing. It also integrates with the company's network system to achieve fully intelligent management of elevator control board testing. This not only promotes factory production but also significantly improves the level of factory automation. Therefore, we have designed an automatic testing device for high-power motor controllers.
