Abstract: An apparatus for estimating DC motor brush wear comprising: a wear element calculator adapted to calculate a plurality of wear elements from at least one environmental variable; a wear element multiplier adapted to multiply the wear elements by respective ones of a plurality of wear coefficients to yield a plurality of weighted wear elements; and a summer adapted to sum the weighted wear elements to yield a brush wear estimate.
