Design and Analysis of Different Topologies of 4kW Double-Sided Axial-Flux Induction Motor

This paper presents the design, modelling, and analysis of the 4kW double-sided axial-flux induction motor (AFIM). The proposed double-sided AFIMs consists of three different topologies, single reduced back-iron rotor with two outer stators, two outer rotors with a single toroidal-wound stator, and single distributed-wound stator with reduced back-iron and two outer rotors. The finite-element method (FEM) is employed to predict the electromagnetic performance of each configuration. The objective is to compare these topologies regarding their efficiency, starting performance, torque/power density and material weight, thereby highlighting the strengths and weaknesses of each proposed topology.
