共振式直线电机的电磁分析

Electromagnetic Analysis of A Resonant Linear Motor

在一般“电器学”文献中，对Ｅ型磁路进行分析时，除了必须考虑气隙磁阻之外．对铁磁阻和窗口漏磁这两个因素，常常根据具体情况选择其一；在求解电磁力时又常常把电流的时间函数作为已知量。本文在Ｅ型磁路的分析中．除了考虑气隙磁阻之外，对上述的后两个因素则同时予以考虑，在求解电磁力时则把电压的时间函数作为已知量。结果表明：这些改进能够满足电机设计的需要。

In usual 'electromagnetic devices',besides the air gap reluctance must be considered in analysis of E-shaped magnetic circuit,only one of the factors,the core reluctance and the magnetic leakge over the window is taken into account according to concrete conditiohs.In evaluating the electromagnetic force,the current function would be treatal as known volume.In this paper these two factors,besided the air gap reluctance,are considered simultaneouly,and the voltage function is treated as known volume.So that the requirement of motor design can be fulfilled.
