Rotary transformer has gradually become used in rotary ultrasonic machining device for power transmission. Compared with contact power transmission, such as slip ring, the contactless power transfer system makes it possible to transmit power without friction, abrasion, vibration and heat. However, in rotary ultrasonic grinding, the varieties of temperature and mechanical load will greatly impact the transmission performance of the contactless energy transfer circuit. This study presents a simple mathematical model of four circuit compensation topologies, which is applicable for non‐ideal condition, and explores the transmission efficiency, output power, and voltage of compensation elements under different temperature and mechanical loads based on this model. The optimal compensation method for the rotary ultrasonic grinding is determined by comparison.
