Electromechanical assemblies with electronics and mechanics are integrated into vehicles. The common features are the direct connection of a motor unit with a motion mechanics, increasingly also with a power electronics. Fuel pumps, radiator fans and windshield wipers are typical examples. Cooling fans dissipate the heat from the cooler to the outside, fuel pumps serve to provide the required amount of fuel. Windshield wipers are used in a variety of vehicles for cleaning the windshields and serve to improve driving comfort and driving safety, for example passenger cars, trucks, airplanes, rail vehicles and water vehicles. They are driven by one or several mostly revolving electric motors. The wiper blade with rubber profile, The wiper arm made of metal and the electric motor belong to a typical construction. A lever mechanism sets the wiper arm in motion. Alternatively, revision motors generate the two directions of movement of the wipers.
