AMETEK Technical & Industrial Products (Harleysville, PA) offers the Pittman® Series 8540 30-mm brush-commutated DC motors that integrate bonded neodymium magnets and 7-slot straight armature to minimize cogging. The motors feature a diamond-turned commutator and copper-graphite brushes for high current capacity. The motors are 1.181" in diameter and are available in three standard lengths of 2.080, 2.552, and 3.025". They achieve continuous torque to 9.3 oz-in and continuous power to 43W, depending on model. They also feature peak torque up to 78.7 oz-in and speeds to 6440 rpm at continuous torque for standard motors at rated voltages.
A PC board brush card with integral surface-mount components incorporates electrical noise suppression, and an integral connector header enables custom leadwire configurations. The modular design accommodates gearboxes, encoders, and brakes using adapter plates and shaft extension modifications.
