Electromagnetic Design and Analysis of High-Speed Asynchronous Traction Motors for High-Speed Rail
This study focuses on the electromagnetic design of high-speed rail asynchronous traction motors,utilizing fundamental theories of motor design.Initially,a thorough analysis of the requirements of the high-speed rail traction system was conducted,systematically examining the electromagnetic design demands of asynchronous traction motors.During the design phase,fundamental motor design theories were applied,encompassing the selection of key parameters such as the number of poles,stator core dimensions,and air gap length.Following the completion of motor size design,a detailed calculation of performance parameters at various characteristic operating points of the traction motor was performed.Subsequently,finite element simulation technology was employed to conduct a two-dimensional electromagnetic simulation analysis of the motor under rated operating conditions.A comparative analysis between the simulation results and electromagnetic calculations demonstrated that the stator phase current and output torque of the motor fell within the permissible error range,meeting engineering design requirements.This study provides specific and insightful theoretical guidance for the electromagnetic design of high-speed rail asynchronous traction motors,offering considerable value for engineering applications.
