Abstract
The supertemperature in the brush-collector contact is harmless when it corresponds to the average contact voltage. But, there are moments when the brush makes inadequate contact. particularly just before leaving a segment. In such moments, transient high voltages and temperatures appear. These events cause wear. The complicated features of the problem, with computations of temperatures and their effects, will be indicated by two numerical examples. Several simplifications are applied.
