Abstract
Purpose – The purpose of this paper is to apply an Ant Colony Optimization approach for the solution of the topological design of interior permanent magnet (IPM) machines.
Design/methodology/approach – The IPM motor design domain is discretised into a suitable equivalent graph representation and an Ant System (AS) algorithm is employed to achieve an efficient distribution of materials into this graph.
Findings – The single-objective problems associated with the maximization of the torque and with the maximization of the shape smoothness of the IPM are investigated. The rotor of the device is discretised into a 9x18 grid in both cases, and three different materials are considered: air, iron and permanent magnet.
Research limitations/implications – The graph representation used enables the solution of topological design problems with an arbitrary number of materials, which is relevant for 2 and 3D problems.
Originality/value – From the numerical experiments, the AS algorithm was able to achieve reasonable shapes and torque values for both design problems. The results show the relevance of the mechanism for multi-domain topology optimization of electromagnetic devices.
