Design, Analysis and Implementation of a MHz-Class Integrated Wireless Motor

Yuteng Yan, Ning Kang, Huanzhi Wang, Christopher H. T. Lee

IEEE Journal of Emerging and Selected Topics in Power Electronics, Early Access

Introduces the integrated wireless motor, in which the receiving coil, power converter and motor are consolidated into a single compact unit, and establishes a holistic design paradigm for 6.78-MHz systems. Multi-domain simulations quantify the motor's ferromagnetic interference on the coils and the dynamic load fluctuations of the drive, leading to a robust WPT design whose prototype demonstrates superior power density and operational robustness.

28th International Conference on Electrical Machines and Systems

Proposes a flexible annular receiving coil made of two oppositely wound sub-coils that harvest power from both faces of the transmitting coil. The prototype holds a DC bus of about 20 V across 0–60° of rotation, removing the strict coil-alignment constraint of existing wireless motors.

Design of a GaN-Based Power Converter for Small-Sized Integrated Motor Drives

Yuteng Yan, You Zhou, Ning Kang, Shuangchun Xie, Guanghui Yang, Christopher H. T. Lee

IEEE Transportation Electrification Conference and Expo, Asia-Pacific

Presents an 80-mm circular GaN power converter designed to fit the end of a small servo motor housing for integrated motor drives, combining a three-phase inverter, on-board power conversion and current sensing and protection. The prototype drives a 100-W PMSM with symmetric, stable three-phase currents.
