According to the company, its brush-commutated d.c. gearmotors offer increased output torque for applications such as data storage, medical/biotech, semiconductor, and automation. The GM8000, GM9000, and GM14000 brush d.c. gearmotors are offered in varying lengths and with sintered steel spur gears. Series GM8000 gearmotors are available with a range of 11 standard reduction ratios from 6.3:1 to 1,803.6:1; Series GM9000 gearmotors offer 12 ratios from 5.9:1 to 4,732.5:1; and series GM14000 gearmotors offer four ratios from 5.9:1 to 218.4:1. The company says torques up to 500 oz-in can be achieved with select gear ratios and high-strength gears.
Armatures for the gearmotors are skewed to minimize magnetic cogging, and windings are resin-impregnated for reliability in incremental motion applications. Two-pole permanent magnet stators are constructed of ceramic magnets enclosed in heavy-gauge steel return rings. Diamond-turned commutators ensure maximum brush life. Optional customization components include cartridge brush assemblies, encoders, modified shafts, shaft-mounted pulleys, ball bearings, electromechanical brakes, and RFI suppression.
