Electromagnetic Sizing of Axial-Flux Induction Machines and Experimental Validation
Abstract: With a rising drive towards greener means of transportation, electrical machines for propulsion are becoming a scientific field of major interest. In particular, part of the research studying these devices focuses its efforts on axial-flux machines, which compared to radial-flux machines can offer a better length-to-diameter ratio and higher torque arm for similar ratings. The analysis carried out throughout this degree project deals with the development and testing of an electromagnetic sizing algorithm for double-stator axial-flux induction machines (DS-AFIM). The designs produced by the algorithm are simulated via finite-element method (FEM) and validated through a comparison with measurements taken upon a real machine. The FEM simulated designs show agreement with the experimental values obtained from physical measurements, although material identification procedures are performed to assess the stator lamination’s magnetic properties. The results obtained validate the sizing algorithm and the designs produced by it, thus allowing to fill a gap in the literature regarding this particular machine topology.
