Influence of Production Tolerances and Production Technologies on the Temperature Model of a High-Speed Synchronous Machine with Permanent Magnets

The main aim of this paper is to prove the importance of precision of the manufacturing process during designing and producing the electrical machine. There is made a comparison of several models and shown the dependency on the accuracy of the dimension of the stator core and the contact region between the stator and motor housing. This paper is also focused on the modification and improvement of the passive cooling system of the high-speed electrical machines body. The contribution of the paper is the valuation of the inaccuracy of the prediction thermal calculation in comparison with a real electrical machine.
