Problems solved by technology

[0002] At present, test benches for testing transmission equipment such as various types of motors, hydraulic couplers, and various shaft couplings mainly use manual operation control tests, manual meter reading and recording of test data, including overcurrent tests, temperature rise tests, overvoltage tests, etc. Tests, etc.; this manual test has obvious defects: low work efficiency, relatively high labor intensity, low test accuracy, and the reliability of test data is affected by human factors. With the improvement of test requirements, the existing test Taiwan can no longer meet the requirements
