Pittman DC Motors Integrate Neodymium Magnets Pittman 30mm brush-commutated DC motors integrate high-energy bonded neodymium magnets for maximised power density and magnetic-field profile, and a seven-slot straight armature to minimise cogging. The motors also feature a large diamond-turned commutator and copper-graphite brushes to deliver high-current capacity and long-life operation. The Series 8540 brush DC motors offering high torque-to-size performance that is suitable for power-data storage, as well as medical equipment and business machines. The motors (1.181in diameter) are available in three standard lengths: 2.080, 2.552 and 3.025in). They can achieve continuous torque up to 9.3oz/in, continuous power up to 43W, depending on model, peak torque up to 78.7oz/in and speeds up to 6440rpm at continuous torque for standard motors at rated voltages. Their balanced armature minimises noise and vibration; large pre-loaded and heavy-duty ball bearings and supports promote high sh...
