  • Cut-in resistance for motor vehicle heating fans
    Patent number: 4247842
    Abstract: This specification discloses a cut-in resistance for motor vehicle heating fans with a first resistance wire winding which can be cut into an electric fan motor either alone or in series with a second resistance wire winding. The first winding is arranged in the interior of a ceramic tube and the second winding is arranged on the outside of the ceramic tube. The ceramic tube is retained solely by the ends of the resistance wires which are passed upwards to a ceramic plate and clamped by flat plug contacts. This produces a compact arrangement wherein the ceramic material can safely store generated heat without danger of heat damage to adjacent plastic components.
