Traditional wired DC motors often face challenges associated with cable, copper losses, and magnetic losses, which can have a notable impact on the efficiency and lifespan of the motors. These losses, arising from the nature of the wired connection, can hamper the overall performance and longevity of DC motors. This paper introduces an innovative solution to the challenges posed by traditional wired DC motors, presenting a single-stage class-E resonant wireless power transfer (WPT) technique that controls the DC motor. The proposed WPT system incorporates an interleaved class-E resonant circuit with zero-voltage switching (ZVS) characteristic at the transmitter (Tx) to amplify the output power and improving reliability, enabling efficient handling of the DC motor's changing load conditions under different speeds. Meanwhile, at the receiver (Rx), a full-bridge phase-shift (FBPS) technique is employed to modulate the phase and control the armature voltage supplied to the DC motor, thereby controlling its speed. Numerical results demonstrate that the proposed technique in this paper achieves a maximum efficiency of 96.9% at a phase shift of π.
