圆筒型直线感应电动机暂态特性研究

STUDY OF THE TRANSIENT PERRORMANCE OF A CYLINDRICAL LINEAR INDUCTION MOTOR

采用与传统的用等值参数分析计算电机暂态过程的不同方法，从场的角度，通过暂态电磁场的计算，求取直线感应电机的暂态特性，计算中，比较全面地考虑了饱和、涡流及边端效应和齿槽的影响，计算结果与实验结果的较好吻合表明了该方法的有效性。

By solving transient magnetic field equations,the transient performance of a cylindrical linear induction motor was computed.It is quite different from the traditional method whichusually utilizes equivalent parameters of the machine to calculate its transient performance.In computation,the effects of saturation,eddy current,teeth and slots,and the end effectwere fully taken into account.The agreement of calculated values with test results shows thevalidity of the present method.
