Abstract
An electric machine, in particular a motor, includes a winding support assembly and a measuring system, preferably an infrared measuring system, The measuring system has at least one sensor and an evaluation unit, whereby the measuring system is integrated in the winding support assembly. The infrared sensor, which operates without making contact with the winding support assembly, provides almost instantaneously a measurement value that is proportional to the actual temperature of the winding system, thereby significantly improving motor protection. The sensor can be embedded and sealed in the winding support assembly.
