Abstract

An electric motor with a sensor, in particular an rpm sensor, is proposed. The sensor contains at least one means (20), generating a magnetic field, as the signal emitter, at least one magnetic field sensor (28, 30) as the signal receiver, and signal conducting means (22, 24, 26). The signal conducting means (22, 24, 26) contain magnetically conducting material and conduct the signal of the at least one magnetic field-generating means (20) to the at least one magnetic field sensor (28, 30). At least one current conducting means (40, 42, 44) is arranged essentially along the signal conducting means (22, 24, 26).
