PennEngineering® Motion Technologies (Harleysville, PA) offers PITTMAN® brush-commutated DC gearmotors with output torque to 175 oz-in with standard sintered steel spur gearing, and output torque to 500 oz-in by incorporating select gear ratios and high-strength gears. The Series GM8000 gearmotors are available with a range of 11 standard reduction ratios from 6.3:1 to 1803.6:1. Series GM9000 gearmotors offer 12 ratios from 5.9:1 to 4732.5:1, and Series GM14000 gearmotors feature four ratios from 5.9:1 to 218.4:1.
Armatures are skewed to minimize magnetic cogging, even at low speeds, and windings are resin-impregnated for reliability in incremental motion applications. Two-pole permanent magnet stators are constructed with ceramic magnets enclosed in heavy-gauge steel return rings. Optional components include cartridge brush assemblies, encoders, modified shafts, shaft-mounted pulleys, ball bearings, electromechanical brakes, and RFI suppression.
