Abstract
The present work suggests non-parametric optimization techniques to be included in the design process for electrical machines. The recommended procedure would be to use topology optimization in the conceptual design phase. Then afterwards apply shape optimization for detailed designing. Both build on numerical finite element analysis to solve the primal formulation for the physical domains being low frequency electromagnetic and structural mechanics. The optimization technology uses mathematical programming and adjoint sensitivities, for e.g. outputs of the simulation in the EMAG domain as mean torque, torque ripple and lumped radial tooth forces and in the structural domain as stiffness and strength given by displacements and stresses.
