一种新型直驱旋转-直线电机及其通过谐波电流注入的纹波抑制方法

This article presents a direct-drive multistage rotary–linear machine (RLM) with a dual permanent magnetic (PM) structure. The RLM has prominent direct-drive characteristics, such as high torque/force density, and a deeply integrated mechanical structure, as well as a significant degree of decoupling between the two dimensions of motion. A harmonic current injection method is proposed to reduce to...
