Request Information
The Hansen series 121-8 Planetary Gear DC motor matches our 2.1 inch diameter DC brush motor with a 2 inch diameter metal planetary gear box. 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.
