Design, Analysis and Dynamic Performance of Radial Magnetic Coupling

Akcay, Yusuf; Giangrande, Paolo; Galea, Michael

Abstract

Contactless torque/speed transmission is gaining an ever-increasing interest in industry and mobile applications, since the mechanical wear-out is avoided resulting in lower maintenance costs. The radial topology is one possible configuration for magnetic couplings (MCs) and its main components are two concentric rings equipped with permanent magnets (PMs). The transmitted torque value depends on an angular shift between the inner and outer rings and greater shift angles lead to higher transfer torque. Hence, the shift angle is a crucial design parameter and defines the dynamic performance of the MC. In this paper, a radial MC is designed based on 2D analytical subdomain approach and validated against 3D finite element simulations. The 3D model is then employed to evaluate the torque transmission capability of the designed radial MC. Finally, the dynamic performance is investigated in terms of disturbance rejection under several load torque values including the mechanical features of the considered test bench.
