Energy and cost-saving adaptation of material use for electrical drive has metal rails let into bush to make good thermal contact with cylindrical aperture of stator plate packet fitted onto bush

摘要

The arrangement has a tubular bush that is made of a synthetic material and that carries a stator packet and a bearing with a flange formed on the bush that is designed so that metal rails let into the periphery of the bush in the axial direction make a good large area thermal contact with the cylindrical aperture of the stator plate packet that is fitted onto the bush. Metal strips attached to the ends of the rails radiate heat without vibration.
