Abstract: A compact electric motor (1) includes a housing (2), a stator (3), a rotor (4) with a rotor winding (5) or permanent magnets located thereon. A thermal protection device protects the electric motor against overheating. A sensor unit (6) is provided as a thermal protection device. The sensor unit (6) includes a temperature sensor (7) for detecting temperature-based measurement values, a radio module (8) with an antenna (8a) for sending sensor signals of temperature-based measurement values or data or information derived therefrom by radio to an external receiving unit (9). The sensor unit (6) has a memory (13) and a microcontroller (10). The sensor unit (6) is a self-supplying assembly.

Abstract: A fuse component (1) has a fuse element (2). The fuse element (2) is located inside an isolating body (3) and the fuse element (2) extends between the two end faces of the isolating body (3). Each of the end faces of the isolating body (3) are closed by electrical conductive end caps (4) and the end caps (4) are in electrical contact with the fuse element (2). The isolating body (3) includes at least two shells (5a, 5b); at least in the region of the end caps (4), and the shells (5a, 5b) in the assembled state form a channel (6) to receive the fuse element (2).
