The synthesis of electro-mechanic actuators is formulated as a constrained
optimization problem where some performance function of the device is to be
met, subject to the satisfaction of some constraints about its dimensions
and supply conditions. The optimization problem is tackled by means of a ge
netic algorithm coupled to a multi-objective definition of the objective fu
nction that merge together objectives and constraints in one single scalar
objective function A fast magnetic analysis tool has been developed so that
the computational cost of the genetic optimization run is acceptable. Some
results about the synthesis of a tubular linear motor in two sizes are pre
sented and discussed.
