This paper presents a comprehensive approach to design of series of permanent magnet assisted synchronous reluctance motors using combined analytical and finite element calculations. A global optimisation metaheuristic algorithm (differential evolution) is utilised in order to achieve optimal design in terms of maximum torque per volume with numerous specific boundaries imposed on motor geometry and performance. A novel approach to the calculation of the specified constant power speed range and demagnetisation effect in sudden symmetrical short circuit using iterative finite element magnetostatic simulations is presented. Based on the results of optimised design, a 100 kW prototype was built and tested.
