Stand for electric machine e.g. electric motor, has sheet material layer which is arranged between adjacent layers of metal sheets, whose thermal conductivity is larger than the thermal conductivity of the metal sheets

摘要

The stand (10) has rotor and stator having several stator windings (20). The stator is associated with a heat sink (26). The stand unit (12) is made of stacked layers of metal sheets (12a). A sheet material layer (30) made of aluminum nitride and graphite is arranged between adjacent layers of metal sheets, whose thermal conductivity is larger than the thermal conductivity of the metal sheets.
