Optimal electromagnetic-thermo-mechanical integrated design for surface mount permanent magnet machines considering load profiles

Most existing design and optimization methods treat the electromagnetic, thermal and mechanical designs separately. As a result, the effects of power supply, machine control, load profile, thermal effects and materials are not fully integrated and accounted for, which often leads to over- or under- design. This paper proposes an innovative and computationally efficient approach which integrates the electromagnetic and thermo-mechanical design for Surface Mount Permanent Magnet (SMPM) machines. Particle Swarm Optimization (PSO) is part of this integrated process to efficiently find designs which optimize certain requirements, such as weight, efficiency, etc. for example. The effects of power supplies, machine controls, load profiles, thermal effects and materials can thus all be considered systematically in the proposed multi-physics design approach.
