摘　　要：结合等效电路,深入研究了圆筒型直线感应电机电磁参数的确定与计算方法,给出了次级阻抗的直接计算公式。采用所提出的方法对一台电机进行分析,并通过有限元法证明了等效电路分析结果的准确性。和传统的逐步逼近方法相比,次级阻抗的直接计算方法具有应用方便的突出优点。Combining equivalent circuit of tubular linear induction motor, the determination and computation method of electromagnetic parameter are deeply studied and direct calculation formula of secondary impedance is given in this paper. A motor is analyzed using proposed method, and accuracy of analysis result from equivalent circuit is proved by FEM. Compared with traditional method of successive approximation, the direct calculation method has prominent merit for application.
