Abstract

This article presented a single-phase shaded-pole induction motor (SPIM) system, which aims to work in an isolated environment. Compared with the previous wireless SPIM, this system employs less controlled switches and can work at full-resonant condition, while retaining the merit of secondary controllerless. The key is to employ a half-bridge inverter and a proper dual-frequency resonant network; thus, only two controlled switches are adopted at the motor side. Since the SPIM is purposely designed with a dual-stator winding, the system robustness and efficiency can be significantly improved. In this article, simulation has been conducted to verify the system's feasibility and self-drive ability. Meanwhile, a 30-W prototype has been built for the experimental verification, and the results show that this motor can achieve flexible speed control with the transfer distance of 20 mm and the transmission efficiency of 77%.
