Electric motor or generator has bifilar temperature sensor used for monitoring temperature or temperature variation of rotor or stator winding packet

摘要

The electric motor or generator has a rotor and a stator (1), at least one of which has conductor windings (2) providing at least one winding packet (3). A bifilar temperature sensor (4) is used for monitoring the temperature or temperature variation of the winding packet, e.g. by winding it in a helix around the outside of the winding packet.
