Gearmotors Offer More Power in Smaller Package
These 22-mm DC gearmotors (Series 6000) are available in three standard motor lengths: 1.256 in./31.90 mm, 1.556 in./39.52 mm, and 1.901 in./48.29 mm. Sturdy gearbox construction incorporates either metal gearing to promote high torque capacity or economical plastic gearing to reduce audible noise. Both gearbox versions offer the capability of bi-directional rotation.
Depending on type, the gearboxes range in length from 0.768 in./19.5 mm to 2.02 in./51.3 mm, weigh from 2.9 oz/81 g to 3.7 oz/106 g, and can deliver reduction ratios from 4:1 to 429:1. Maximum load capabilities range from 7 oz-in./0.05 Nm to 99 oz-in./0.7 Nm and continuous torque up to 0.7 Nm can be achieved. Continuous load torque capability will vary with gear ratio, motor selection, and operating conditions.
Key gearmotor features include skewed five-slot armature design, bonded neodymium magnets, two-pole stators, heavy-gauge steel housing, silicon steel laminations, and copper graphite brushes. Options include ball bearings, EMI/RFI filter networks, leadwire or terminal connection configurations, and optical encoders. The gearboxes can be specified in various mounting and shaft configurations; output ball bearings can be added for high radial loads; and additional reduction ratios can be developed.
