With the implementation of the national motor energy efficiency improvement plan, in response to the call for "energy conservation and emission reduction", the demand for motor test benches from various motor manufacturers and testing units is increasing. High voltage motor test benches are mainly used for motor type testing, factory testing, and energy efficiency evaluation. The system mainly includes three parts: test power supply, testing system, and operating platform. Among them, testing the waveform quality of the power supply and the accuracy of the testing system are the key factors affecting the scientific and accurate data of the test results.

The fully automatic motor comprehensive testing platform adopts advanced virtual instrument technology, combining the powerful computing power of computers with the hardware measurement and control capabilities of instrument equipment. It is reliable and reliable to use, and the main items are displayed in color with Chinese operation prompts to achieve real-time monitoring of the entire testing process.

The system realizes the control of testing, operation, analysis, processing, display, printing, and storage of data, surpassing the simple combination of traditional instruments in terms of functional sources, especially in terms of result saving, waveform storage, synchronous measurement, test report generation, system expansion, and multifunctionality. Fully automatic, fully microcomputer, high Efficiency and safety Full functional design and anti misoperation measures. The interface operates in both Chinese and English, automatically collects measurement data, generates factory test reports based on calculation results, and prints them out. The measurement and control system adopts PLC programming control, which is particularly suitable for products that require batch testing.
