[Claim for Utility Model Registration] A ferromagnetic material is placed at a position spaced apart by the necessary dimension from the contact sliding surface of the carbon brush with the commutator, and as the carbon brush wears, the contact sliding surface and the ferromagnetic material When the distance between the body and the body reaches a predetermined dimension, the ferromagnetic material is set so as to become a component within the brush tube in a magnetic circuit that forms part of the outside of the brush tube, and Current flows through this magnetic circuit, including a magnet or electromagnet that generates magnetic velocity, a Hall element, a reed switch, or a coil. A brush wear detection device equipped with an element that detects changes in magnetic flux.
