The mechanical deformation of two rectangular conductors embedded in a slot mainly depends on the acting electromagnetic volume force density inside the conducting regions, the mechanical properties of the used materials and the applied mechanical slot wedge fixing. With this problem, the behaviour is completely different between mechanical loose and mechanical fixed conductors inside a slot. Loose conductors can only be shortened or stretched due to the acting electromagnetic volume forces, whereby the mechanical behaviour of fixed conductors additionally depends on the mechanical pre-load. The mechanical stress distribution and the accompanied deformation are calculated in an
analytical way separately for both cases of loose and fixed electrical
conductors.
