Though they are frequently overlooked, carbon brushes are one of the most critical elements of a motor.
A carbon brush, also known as a motor brush, is the small part of the motor that conducts electrical current between the stationary wires (stator) and the rotating wires (rotor) of a motor or generator. The brush is made up of one or more carbon blocks and can come with one or more terminals. Read more..
Brush holders may be divided into two broad classes; one in which the brush is rigidly attached to a swivel arm, and the other one in which the brush is free to slide through the supporting box. Read more..
A slip ring is an electromechanical device that allows the transmission of power and electrical signals from a stationary to a rotating structure. The electrical connection to the rotor is made by connections to the brushes. We also make brushes with inserts for cleaning action to minimize the slip ring wear. Read more..
(Carbon strips for pantographs and third rail shoes)
Electric current collectors are used to carry electrical power from overhead lines or electrical third rails to the electrical equipment of the vehicles. The overhead wires ones are roof-mounted devices and those with third rails are mounted on the bogies. Read more..
