چکیده
⎯A permanent magnet linear synchronous motor (PMLSM) for a high temperature superconducting (HTS) maglev system has been studied, including the motor structure, control strategy, and analysis techniques. Finite element analysis (FEA) of magnetic field is conducted to accurately calculate major motor parameters. Equivalent electrical circuit is used to predict the drive’s steady-state characteristics, and a phase variable model is applied to predict the dynamic performance. Preliminary experiment with a prototype has been made to verify the theoretical analysis and the HTS-PM synchronous driving technology. Index Terms⎯High temperature superconducting (HTS), HTS magnetic levitation, maglev transportation system, permanent magnet linear synchronous motor.
