A Novel Magnetically Coupled Resonant Wireless Power Transfer Technique Used in Rotary Ultrasonic Machining Process

Abstract

The existing contactless energy transfer of rotary ultrasonic machining equipment involves a small transmission distance (0.1-1 mm). In this research, magnetically coupled resonant wireless power transfer was used in rotary ultrasonic machining process. A series of theoretical models were established to explore the transmission characteristics of the system, and experiments were carried out to verify transmission characteristics.
