LO-COG® Series 8000 Brush DC Motors and Gearmotors Feature Skewed Armatures to Minimize Cogging


HARLEYSVILLE, PA, July 2, 2002 -- LO-COG® Series 8000 brush-commutated DC motors and gearmotors from Pittman feature seven-slot skewed armatures designed to minimize magnetic cogging (or reluctance torque) even at low speeds, which promotes their smooth and quiet operation. This family of brush DC motors and gearmotors offers performance, reliability, and long life in a relatively small package for a wide range of power applications, including technology for computer peripherals, imaging, and clinical diagnostic devices.

LO-COG Series 8000 motors are available in three lengths and can achieve peak torques up to 16.8 oz-in and speeds up to 10,650 RPM for standard motors at rated voltages. LO-COG Series GM8000 gearmotors are offered in three lengths with 11 ratios from 6.3:1 to 1803.6:1 and can achieve peak torques to 100 oz-in (standard) or 160 oz-in (with high-torque wide-face gears). Speed, voltage, current, and torque characteristics can be varied to meet specific needs.

Commutators are diamond turned after armature assembly to ensure optimum concentricity and long brush life. Windings are resin-impregnated for greater reliability in incremental motion applications. Copper graphite brushes are standard.

Modular construction enables these motors and gearmotors to be customized with alternate brush materials, encoders, timing belt pulleys, brakes, cables, connectors, modified shafts, and RFI suppression or other special configurations to meet application requirements.

Every Pittman motor is subjected to automated performance testing prior to shipment.
