Nowadays, designers typically use modeling tools and numerical calculation for the electrical machine sizing, particularly the finite element method. The finite element method has been validated and has proved to be a very efficient one. However, due to problem complexity, this method is still time-consuming and large computer memory is needed. In this paper, we propose a faster analytical model (magnetic and thermal) coupled with an optimization tool CADES (Component Architecture for the Design of Engineering Systems) [1-2] to optimize a range of machines (from a few kW to more than 300 kW, and for speed ranges from 100 rpm to more than 5500 rpm). For this we used a deterministic optimization algorithm called Sequential Quadratic Programming (SQP) [3-4].
