Abstract
An electric machine having a stator winding which is impregnated by total immersion. The bar ends of the stator winding have soldering lugs which are insulated from one another and with respect to grounded housing parts. In order to simplify the assembly of the soldering lug insulation and at the same time to improve heat transfer, the soldering lugs are surrounded on all sides by a deformable insulating material with is pervious to impregnating resin. The insulating material is fixed by means of a shrinkable fabric which is likewise pervious to the impregnating resin. The insulation and shrinkable fabric are impregnated and cured at the same time as the winding insulation.
