APPARATUS FOR MONITORING OF BRUSHES, IN PARTICULAR SLIPRING OR COMMUTATOR BRUSHES, ON ELECTRICAL MACHINES

摘要

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.
