The Hansen series 121-8 gear motor matches our 2.1" diameter DC brush motor with a 2" diameter metal planetary gearbox. The planet gears share the load attached to the output shaft giving the planetary arrangement a higher torque to volume ratio with low backlash compared to a spur gear arrangement. Dozens of ratios are available up to 2653:1. Encoders can also be added.
