According to the task requirements of the national key research and development plan project "Electromechanical integration remanufacturing upgrade technology for waste intelligent equipment"-"On-line monitoring technology for health status of remanufactured products in service", the Institute of Electrotechnics of Chinese Academy of Sciences has developed a comprehensive detection device (model specification: IDDEM-01) suitable for monitoring the service status of various types of remanufactured motors such as remanufactured direct-start permanent magnet synchronous motors. The device adopts a current clamp with a test range of 0A~100A (accuracy 0.2%), a voltage clamp with a withstand voltage of 3,000 V, a patch temperature sensor with a temperature measurement range of -50 ~ +150℃, a photoelectric speed sensor with a speed measurement range of 1 ~ 1~10000rps, and a vibration sensor with a vibration speed detection range of 0 ~ 20 mm/s and an acceleration measurement range of 4g. The field operation data of a remanufactured 30kW three-phase permanent magnet synchronous motor developed by Beijing-Tianjin-Hebei Remanufacturing Industry Technology Research Institute and put into operation in Beijing Jiangong Civil Engineering Co., Ltd. were tested, with an operating voltage of 380V and a maximum operating power of 14kW. The test wiring of the field device and the testing motor was completed at 15: 00 on November 23, 2021, and continuous monitoring was started until 16: 00 on December 8, 2021. After continuous operation for 16 days, about 385 hours, nearly 1.3 million pieces of data were formed. The starting file of data was "Motor Application 1.xlsx", followed by "Application 2" to "Application 7", and the ending file was "Motor Application 7.xlsx".
This document is the intermediate stage "Application 5".
