1 BULLETIN LCG Series GM8000, GM9000, GM14900 LO-COG DC Gearmotors Pittman brand LO-COG brush-commutated DC gearmotors offer smooth, quiet operation and long life. LO-COG gearmotors feature sintered steel spur gears and are available with several reduction ratios and torque ratings to provide an economical solution for a wide range of applications. Armatures are skewed to minimize magnetic cogging, even at low speeds, and windings are resin impregnated for greater reliability in incremental motion applications. An innovative cartridge brush assembly reduces audible and electrical noise and significantly improves brush life by maintaining optimum brush force throughout the life of the motor. For precision motor control, Hewlett-Packard optical encoders are available in 2 or 3 channel versions with several CP ranges to meet your position, velocity and direction feedback needs. Construction 2 pole permanent magnet stators are constructed of ceramic magnets enclosed in heavy-gauge steel return rings Diamond turned commutators ensure maximum brush life Standard copper graphite brushes (Other brush materials available) Precision ground hardened stainless steel shafts Silicon-steel laminations Self-aligning, sintered bronze bearings Options High-torque gears or high-torque wide-face gears Low noise, primary cluster gears Custom cables Multiple shaft configurations Shaft-mounted pulleys and gears Ball bearings Multiple windings Electromechanical brakes Integrated Hewlett-Packard optical encoders Adaptors available for other encoders FI suppression Dynamic armature balancing Series GM ratios from to Peak s to 100 oz in standard 160 and 175 oz in gearheads optional Available in 3 motor lengths Encoder resolutions from 96 to 1024 Series GM ratios from to Peak s to 175 oz in standard 300 and 500 oz in gearheads optional Available in 6 motor lengths Encoder resolutions from 96 to 2048 Series GM ratios from to Peak s to 175 oz in standard 300 and 500 oz in gearheads optional Available in 7 motor lengths Encoder resolutions from 96 to 2048 Get same day shipment of sample motors for models listed in the Pittman Express Catalog (Bulletin PE). Every Pittman motor is subjected to automated performance testing prior to shipment. LCG-1
