A Commutator is a rotary electrical switch in DC electric motors or electrical generators that periodically reverses the current direction between the rotor and the external circuit. In a motor, it applies power to the best location on the rotor, and in a generator, picks off power similarly. As a switch, it has exceptionally long life, considering the number of circuit makes and breaks that occur in normal operation.Even though commutators are perceived as old technology there are still a large amount of dc motors in use today, especially in the Mining industry.YNF Engineering manufactures and repairs all types and makes of commutators and slip rings.Commutators are made up of hundreds of individual parts that have to remain stable in relation to each other at varying speeds and at differing temperatures and humidity. During production, commutators are heated and pressed to a point where they will remain stable under any conditions.
YNF Engineering takes great care in producing and maintaining Commutators that are trustworthy and durable
