Definitions
- the residual air gap disks which have previously been used and which have a plurality of circumferentially spaced recesses are relatively unstable and therefore susceptible to deformations which can occur during the assembly process; Furthermore, the previously used, large flow cross-sectional areas releasing residual air gap discs on a relatively large unevenness.
- the residual air gap set on a magnet group prevents the armature, in particular the armature plate with the armature pole surface, from adhering hydraulically or magnetically to the end face of the magnet core.
