Presented field-circuit coupled adaptive time-stepping finite element method to study on permanent magnet linear synchronous motor (PMLSM) characteristics fed by SPWM voltage source inverter. In air-gap field where the direction or magnitude of the field is changing rapidly, the smallest elements are demanded due to high accuracy to use adaptive meshing technique. The co-simulation was used with the status space functions and time-step finite element functions, in which time-step of the status space functions was the smallest than finite element functions’. The magnitude relation of the normal electromagnetic force and tangential electromagnetic force and the period were attained, and current curve was very abrupt at current zero area due to the bigger resistance and leakage reactance, including main characteristics of motor voltage and velocity. The simulation results compare triumphantly with the experiments results. [ABSTRACT FROM AUTHOR] |
