Pittman 30mm brush-commutated DC motors from Ametek integrate high-energy bonded neodymium magnets for maximized power density and an optimized magnetic field profile and a 7-slot straight armature to minimize cogging. These brush DC motors also feature a large diamond-turned commutator and copper-graphite brushes to deliver high current capacity. Available in three standard lengths, 2.080 in., 2.552 in. and 3.025 in., they achieve continuous torque up to 9.3 oz-in., continuous power up to 43W, peak torque up to 78.7 oz-in and speeds up to 6440 rpm. Their balanced armature minimizes noise and vibration.
