Magnetic Coupled Wireless Motor Driving Systems–An Overview

Magnetic coupled wireless motor (MC-WM) drive technology embodies the deep integration of magnetic coupled wireless power transfer technology (MC-WPT) and motor drive technology, which is currently a forward-looking and challenging research direction in the field of motor system research. Firstly, this paper analyzes the basic operating mechanism of the MC-WM and classifies the topology design methods of the current MC-WM. Moreover, a systematic analysis and evaluation of the research status of wireless driving topology as well as the control methods for different types of motors is conducted. Especially, the construction methods of MC-WM without controllers or active switches in the motor side are discussed. Finally, the research challenges and development trends of MC-WM are addressed.
