Stator for electric machine in e.g. hybrid vehicle, has contact structures experienced high thermal expansion than surrounding areas of plant surface due to geometry of contact structure during heating of stator

摘要

The stator (1) has a plant surface (7) lying outside, in which the stator is fixed in a housing (5). Contact structures are formed in a region of the plant surface, where the contact structures experience high thermal expansion than surrounding areas of the plant surface due to geometry of the contact structures during heating of the stator. The contact structures comprise bars that enclose a recess. The contact structures comprise dimensions allowing small heat flow than the surrounding area of the plant surface during an inserted state of the stator in the housing.
