An example of a carbon brush of a type used in Canada. Part of a large and varied collection of over 7500 electrical items acquired and documented by Ontario Hydro in the1960s. The collection was thought to be the largest and most comprehensive of its kind in Canada and was donated to the National Museum of Science and Technology in 1992.
Function
A current-carrying brush made up of amorphous carbon, carbon and graphite or carbon and copper, used in motors, generators, variable resistors and variable auto transformers., to conduct current between between stationary wires and moving parts. (Refs.2-3). They are often used in fractional horse power motors on electric fans, vacuum cleaners, washing machines, drills and other tools and appliances for collecting current from the commutator of a dynamo or supplying current to the commutator of a motor.
