Pittman brand 30 mm brush-commutated DC motors integrate high-energy bonded neodymium magnets for maximized power density and an optimized magnetic field profile and 7-slot straight armature to minimize cogging. The motors feature a large diamond-turned commutator and copper-graphite brushes to deliver high current capacity and long-life operation. These Series 8540 brush DC motors offering high torque-to-size performance for power data storage and medical equipment and business machines, among other industry applications. The motors (1.181 in. diameter) are available in three standard lengths (2.080 in., 2.552 in., and 3.025 in.). They can achieve continuous torque up to 9.3 oz-in. and continuous power up to 43W, depending on model, and peak torque up to 78.7 oz-in and speeds up to 6440 rpm at continuous torque for standard motors at rated voltages.
