摘  要：介绍了一类应用于平面电动机的、具有多相绕组配置的、有铁心式电枢（简称平面电枢）的结构特点，建立了此类平面电枢的磁动势基波函数。利用磁场基本定律和磁场能量计算方法，推导了气隙磁场能量表达式。根据电感的基本定义，在气隙磁场能量表达式中，引入电感（包括自感和互感）系数。基于微积分即级数理论，对电感系数表达式进行简化，获得形式简单的电感计算模型。针对对称运行模式，获得了主电感和谐波漏磁电感的计算公式。此工作不仅解决了平面电动机主电感计算问题，而且，将传统电机学理论中的一维分布绕组电感计算方法拓展到二维平面分布绕组的主电感计算场合。

Abstract:Introduced a planar armature with multi-phase configuration and iron core.Established the fundamental potential function.According to magnetic field theory,a magnetic energy equation was derived.Some variables named as selfinductance and mutual-inductance were introduced into the magnetic energy equation.By using mathematical theory,the models for calculating the inductions were obtained.The models are the functions of the air-gap thickness,the pole-pair number and the number of turns in series per phase.For the symmetrical operation mode,the main induction and leakage induction weredefined.The equations for calculating the main induction and leakage induction of symmetrical operation system was derived.The contribution of this paper was to extend the method of calculating the inductions of the rotary motor with one-dimension distribution windings to calculating the induction of planar motors with iron core.
