Common commutator wear patterns. It's relatively easy to judge DC motor performance by looking at the commutator. During normal commutation, brush current vaporizes some copper molecules, depositing a ...

Commutators and Compactness in Schrödinger Operators Publication Trend The graph below shows the total number of publications each year in Commutators and Compactness in Schrödinger Operators.

The commutator bars are soldered to armature coils. The brush/commutator combination makes a sliding switch that energizes particular portions of the armature, based on the position of the rotor.
