Abstract
In order to determine the temperature in the winding region of an electric motor, especially linear motor, a measuring line made of uniform; electrically conductive material is integrated in a winding, preferably in sections between winding teeth. The measuring line may be configured as insulated double line which is short-circuited on one side. A change in the resistance value of the measuring line allows conclusion about a temperature change and is easy to ascertain.
