Design and Analysis of A Highly Integrated Wireless Motor Drive System.

This paper proposes and analyzes a new type of wireless machine system called wireless ultrasonic motor system. The system’s most significant feature is removing all active components on the motor side, such as the inverter, power switch, and control unit. The system’s keys are the motor direct drive technology, wireless energy supply, and the transmitting-side motor control. Furthermore, only one matched inductor and resonant circuit are used to improve power quality at the motor side. Finally, the working principle and experimental results are given, which verify the feasibility and correctness of the proposed wireless motor drive system.
