Optymalizacja maszyny dyskowej z magnesami trwałymi i bezrdzeniowym twornikiem z uzwojeniem ewolwentowo-promienowym

In this paper, the construction of high speed disk machine with permanent magnet and coreless armature with involutes-radial winding was presented. Nominal, constructions and material parameters designing machine was defined. To solve magnetic circuit three-dimensional reluctant net method was used. Results of distribution of magnetic induction compare with results getting from finite element method. Method to calculations average and effective value of wire voltage in involutes-radial winding was presented. Thermal calculations for one winding bar was realized using substituted thermal net. Electromagnetic and thermal design calculations were formulated as an optimization problem. Economic criterion expressing cost effective material was assumed. Requirements imposed on design construction were formulated in the form of limitations optimization problem. To solve optimization task, ready procedure based on sequence square programming algorithm was used. Strategy of search of optimal construction was developed. Results of project calculations for different relation of material cost were presented.
