Abstract :
In the paper the optimal shape design of a dc torque motor is considered. Finite element models in 2D and 3D are examined, taking into account the magnetization curves of iron and permanent magnets. A stochastic optimizer of lowest order is then applied to identify the optimal shape of the device exhibiting the minimum cost, subject to a set of geometrical and behavioural constraints. An automatic procedure is set up interfacing optimizer and field simulator; remarks about the search of the global optimum are drawn
