Abstract: In order to solve the ultrasonic frequency and high power transmission problems in rotary ultrasonic vibration machining, the Contactless Power Transmission (CPT) method based on electromagnetic inductive coupling was proposed.The design parameters of contactless loosely coupled transformer were calculated by theoretical analysis.The original boundary impedance matching model with the total load of piezoelectric transducer and contactless loosely coupled transformer was established.The relationship between power frequency, magnetic core spacing and power transmission efficiency was studied by experimental analysis and the trend of temperature variation of magnetic core was tested.The results show that the contactless power transmission system can meet the requirements of rotary ultrasonic vibration machining.

Key words: Contactless Power Transmission (CPT), rotary ultrasonic vibration machining, contactless loosely coupled transformer, impedance matching
