2-D analytical subdomain model for high-speed permanent-magnet machines

This paper presents a subdomain model suitable for high-speed surface-mounted permanent-magnet machines. The model is presented with a focus on computation time and calculations of some relevant values particular to high-speed machines. The results are compared to both finite element analysis simulations and measurements on an existing prototype. The good accuracy and the high computation speed of the presented model allow an efficient optimization process. Finally, the results are discussed and further developpement are proposed.
