Modeling, Analysis, and Implementation of a Novel Wireless-Moving-Levitating System with Multiple Magnetic Fields

This paper proposes a novel wireless-moving-levitating system (WMLS) using multiple magnetic fields to explore the effectiveness of wireless-moving-levitating manipulation in hard-to-reach environments. The modeling, simulation, implementation, and analysis of a wireless-moving-levitating light (WMLL) are presented. The WMLL is an illustration to show the validity of the proposed WMLS. A mechanical structure is designed to construct the WMLL. A levitation force, which resists the gravity to levitate a light-emitting diode (LED) disk, generated by permanent magnets and energized coreless winding is then derived. A module of wireless power transmission is further applied to provide power to the LED disk. Two hybrid stepper motors are employed to achieve planar motion of the LED disk. Additionally, a control scheme is developed to regulate the energized current for stable, quick, and accurate levitation of the LED disk. Simulation is performed to characterize the WMLL by using ANSYS software (Ansoft Maxwell software). Finally, the effectiveness of the proposed WMLS is verified through the experimental results of a developed prototype.
