Abstract

An in-wheel motor system can drive an in-wheel motor stably, and also allows power feeding from the road surface, even when transmission and reception coils are misaligned. An in-wheel motor system () includes a power transmitter () that utilizes a resonance phenomenon using a magnetic field. The power transmitter () transmits power (P) wirelessly from the vehicle body to an in-wheel motor () mounted in a wheel. The in-wheel motor system () may also include a communication interface () that communicates between the vehicle body and the wheel, and the communication interface () may transmit a control signal (CTL) for driving the in-wheel motor.
