摘　　要：将麦克斯韦方程和绕组函数法相结合,得到单边直线感应电机(single linear induction motor,SLIM)的初级、次级基波和边端效应波绕组函数。由绕组函数理论计算出电感、运动电势系数,建立电压和磁链方程。由初、次级能量关系得到推力方程并进一步求解相关特性量。对不同工况的暂态和稳态特性进行分析。将大功率电机全过程中相电流、推力、效率的计算值与测量值进行比较。试验结果表明,绕组函数法能较合理地描述SLIM特性,具有一定实用性。Single linear induction motor （SLIM） primary, secondary fundamental and end effect component winding functions were achieved based on Maxwell equations and winding function method. All inductances, speed voltage coefficients were calculated according to winding theory so that voltage and flux linkage equations were gained. Thrust equation and other performance variables were got according to the relationship between primary and secondary energy. The motor performances in different transient and stable situations were analyzed. The computed phase current, thrust and efficiency of high power motor were compared with their measurement values in the whole operation process. The experiment result indicates that winding function method is feasible and reasonable to describe SLIM characteristic.
