Abstract

A stator for an electric drive, includes a stator housing configured in the form of a stack of laminations and having a stator bore. The housing is surrounded by a cooling jacket and has opposite winding end portions. Tubular insulators abut the bore-confronting inner surface of the winding end portions, whereby the tubular insulators bound respective cavities in concert with end faces of the stator housing and the cooling jacket for receiving the winding end portions, with the cavities being filled with insulating casting material.
