INTRODUCTION On 24 August 2023,the Japanese government insisted on initiating the discharge of Fukushima nuclearcontaminated water into the sea,causing widespread global concerns regarding marine biological safety,seafood and marine resources(TEPCO 2023).Although the Japanese government has consistently emphasized that the nuclear wastewater has been treated using an Advanced Liquid Processing System(ALPS),resulting in very low concentrations of various nuclear elements,and that the International Atomic Energy Agency(IAEA)has conducted real-time monitoring of the treatment process and discharge fow(IAEA 2023),people around the world still harbor signifcant *** are a few reasons for this ongoing apprehension.

Dynamics modeling and electromechanical coupling characteristics analysis of cage induction motors

Science China(Technological Sciences) 2024年第3期67卷 709-724页

作者： zhou ZiWei CHEN ZaiGang ZHAI WanMing State Key Laboratory of Rail Transit Vehicle System Southwest Jiaotong UniversityChengdu 610031China

Induction motors, as typical electromechanical energy conversion devices, have received limited attention in previous studies on electromechanical coupling vibrations, precise modeling, and the use of electromechanical coupling effects for fault diagnosis and condition assessment in motor drive systems. This study proposes a comprehensive model of cage induction motors that integrates the multiple coupled circuit model with a rotor-bearing dynamics model. The model accounts for the linear increase in the magnetomotive force across the slot and incorporates the skidding characteristics of bearings in the rotor-bearing system. By calculating the time-varying mutual inductance parameters based on the air-gap distribution in the vibration environment, the electromechanical coupling vibration of the cage motor is investigated. Furthermore, this study examines the electromechanical coupling vibration characteristics influenced by various factors, including bearing clearances, radial loads, and the vertical excitation frequencies of the stators. The results show that the proposed model improves the excitation inputs for the electrical and mechanical systems of the motor compared with conventional models. Increased bearing clearance and radial load affect the current and torque similarly but have opposite effects on the slip ratio. This study provides a deeper understanding of electromechanical coupling mechanisms and facilitates the use of such phenomena for fault diagnosis and condition assessment in motor-driven systems.
