Slip Rings and Commutators

Commutators are used in most direct current machines and in some alternating current machines. The commutator is pressed onto the axis of the machine part and rotates with the other components. The winding from the rotor of the motor is either welded or soldered to the individual slats which are isolated from one another and from the axis. Commutators consists of a copper alloy, which secures good contact to the carbon brushes.

There are many variants, some are on stock, but often commutators are custom-made, so in many cases, a request must be made.
