1.How do the commutator work?
A single commutator bar is a piece of copper connected to one end of an armature coil. Two commutator bars for each coil, are attached to opposite sides of the shaft.Electrical connection is made by pressing carbon brushes against the commutator bars, this allows the shaft to rotate while making electrical connections when the copper bars are in contatct with a carbon brush.
2.What we need for commutator quotation?
We need commutator drawing which mentioned the detailed size and material. If customer is not clear about the material, we could recommend suitable material according to the application. Also we need to know the required quantity per order.
