Electromagnetic Analysis and Optimization of Absolute Location Sensor for High Speed Maglev Train

摘要

This paper analyzes and optimizes the induction coils of absolute location sensor for high-speed Maglev train. The electromagnetic field model of the induction coils is established. Magnetic field distribution of transmitting coils with single frequency are simulated to evaluate their effects on the receiving coils by Finite Element Analysis(FEA) software ANSOFT. Based on the analysis of simulation results, optimized transmitting coils with multi-transmitting frequencies and receiving coils with difference structure are proposed.
