Pittman® 8540 Series brush-commutated dc motors has a high power density from bonded neodymium magnets. These motors are available in three lengths (2.114 in., 2.585 in., and 3.057 in.) weighing from 4.66 oz. to 7.55 oz. Depending on model, they can achieve continuous torque from 2.5 to 8.3 oz-in. without a heat sink. Speed, voltage, current, and torque characteristics can be varied and a selection of standard windings enables optimized performance tailored to particular application needs. The brush system delivers reliable and consistent performance over a long life due to robust brass brush tracks that keep brushes aligned, constant-force springs that provide optimum brush pressure, and larger brushes offered in a choice of materials (including standard graphite).
