Mechanoelectric Dynamics Analysis of A Resonant Linear Motor

提出了线性振荡电机电磁分析的新思路。在磁路分析中同时考虑了气隙磁阻，铁磁阻、窗口漏磁和磁极端部的磁通扩张效应；在电路分析中同时考虑了电感压降和电阻压降。用直接积分法推理出电磁力与外施电压的解析关系表达式。结果表明这些改进能够满足电机设计的需要。对原理样机进行了试验，证明主要技术指标基本上达到了预期要求。

A new idea of electromagnetic analysis of the linear oscillomotor is deduced here.The air reluctance,the core reluctance,the magnetic leakage over the window and the flux expansion on the pole are considered simultaneously in analysis of the magnetic circuit.The voltages over the inductance and over the resistance are taken into account at the same time in analysis of the electric circuit.By means of direct integral method,an analytic expression related the electromagnetic force with the applied voltage to the motor is deduced.so that the requirement of motor design can be fulfilled. The prototype has been tested and the results proves that the main technical indexes achieve the goal basically.
