Power Transfer Performance and Cutting Force Effects of .

Abstract: In rotary ultrasonic grinding (RUG), a rotating transformer can be used to replace the established slip ring technology and provide a contactless power supply to the revolving transducer. Such contactless energy transfer (CET) is safe, and high rotation speeds are possible. Compared with a closely coupled transformer, the transfer efficiency of the rotating transformer is lower.
