Method for trueing commutators and slip rings

The speed may be adjusted during operation as the grinding wheel wears, or a higher initial speed may be selected, up to the safe rating of the grinding wheel. Generally, lesser wheel speeds result in higher wear rates of the wheel and more dragging of copper on a commutator into insulating spaces between the copper bars 16.

Commutators

With the oldest direct current motor commutator technology in the world, this commutator is still the most commonly used worldwide for traction or for large commutators that cannot be molded. With this technology, the commutator is installed by tightening two steel cones that constitute the hub, which is insulated from the commutator segments by two mica cones.
