摘要
本文根据"场路"复量功率相等的关系,提出了直线感应电动机等值电路(T型和串联等)的通用推导方法。该方法考虑了端部效应的影响,并适应于从一维到三维的电磁场分析。用此方法得到的基于二维场分析的T型等值电路,把次级漏抗和集肤效应的影响都考虑了,它比基于一维场分析所得的等值电路更精确,计算结果与试验值很吻合。
This peper proposes a general deriving method of linear induction motor (LIM)'sequivalant circuit (EC) from the complex powers' equivalent relationship in the electriccircuit and magnetic field analysis. It considers the infuence of the end effects and iseffect to the magnetic field analysis from one dimension to three. A T-form EC derived from two dimensional magnetic analysis with this method contains the secondaryleakage reactance and skin effect. It is more accurate than that derived from one dimensipnal magnetic analysis. The results from calculation and the test are very coincident.
