Patent ID: 7402925

Claim:
A stator for an external rotor electric motor, having a laminated stator core which is provided with a stator winding comprising a connecting arrangement, which is arranged on one end of an end winding of the stator winding, for electrically connecting winding wire ends of the stator winding and connecting wires of a temperature monitor connected with the stator winding, wherein the connecting arrangement has an insulating switching disk which covers one end of the end winding, in the form of a cap, and wherein the temperature monitor is held by the switching disk such that, on the one end of the end winding, the temperature monitor rests between the stator winding and the switching disk such that it is in thermally conductive bearing contact with the stator winding, wherein a spring-elastic pressure force is applied to the temperature monitor by the switching disk, wherein the switching disk has a spring arm, which produces the pressure force, in the region of the temperature monitor, said spring arm being formed by a U-shaped cutout in the region of a wall of the switching disk; wherein the spring arm, on its side pointing away from the temperature monitor, has a bearing element for the purpose of bearing in a supporting manner against an opposing surface; and wherein the bearing element is configured to bear in a supporting manner against the opposing surface in order to increase said spring-elastic pressure force applied to the temperature monitor.
