摘要
提出一种建立永磁直线同步电机(PMLSM)暂态数学模型的方法;采用电机绕组函数理论导出PMLSM三相绕组函数;基于对电机暂态过程气隙磁力线形状的假设,提出初、次级复合气隙磁导系数函数和瞬时电感表达式,建立了PMLSM的暂态数学模型,并对电机的起动过程进行了仿真.该模型较好地考虑了开槽效应、电感参数随电机动子位移及初始位置的变化、端部半填槽等因素.对凸极式永磁直线同步电机及其它电机同样适用.
Presented a method to establish a transient mathematics model of permanent magnet linear synchronous motor （PMLSM）. Three-phase winding function of PMLSM can be attained by motor＇ s winding function theory. On the basis of hypothesis for the transient process of the motor for the shape of magnetic line, primary-secondary air-gap permeance coefficient function and instantaneous inductance expressions were proposed, and then transient mathematic model of PMLSM was established and the motor staring-up duration was simulated, which considered perfectly many factors such as slotting effect, movement of primary-secondary, half - filled slots etc. , and fits to the salient permanent magnet linear synchronous motor and others motor.
