Abstract: An apparatus is disclosed for monitoring brushes, such as slipring or commutator brushes, on electrical machines. At least one electronic sensor is configured to be arranged in or on a brush apparatus of an electrical machine. This sensor is measuring the brush position at high speed and high resolution, and characterized in that it receives a brush position signal from the brushes in a contact-less fashion. Data is collected by a central unit which sends the data to a server computer. Client computers can consult data, and real time monitor the status of the machine.
