Brush for a sliding-track or commutator system of an electrical machine with a monitoring apparatus for wear of the brush and a method for monitoring the wear of a brush

The device has an impedance sensor (24) that is arranged adjacent to a brush (12), which is adjustable in a brush holder (18). A section (36) of the brush has an electrical conductivity, which differs from a conductivity of a basic unit of the brush. A change of the conductivity is detectable by the...

More Information
Summary:The device has an impedance sensor (24) that is arranged adjacent to a brush (12), which is adjustable in a brush holder (18). A section (36) of the brush has an electrical conductivity, which differs from a conductivity of a basic unit of the brush. A change of the conductivity is detectable by the sensor. The section with varying electrical conductivity integrated into the brush is electrically isolated against the basic unit of the brush. An independent claim is also included for a method for monitoring the wear of a brush of a slide path or commutator system of an electrical machine.
