Gear Motor 2 - 224:1 Offset Shaft

Solarbotics is the sole commercial outlet for these impressive 224:1 gearmotors. They are very comparable to a hobby servo for power, at a fraction of the cost!

This motor offers 50 in*oz of torque, rotating 360 degrees every 1.6 seconds (38 rpm - just a hair slower than a servo), at 5V, drawing 600mA at stall (free running at 52mA).

With a 7mm double-flat output shaft (avoid using the "D" output - it's not meant to take rotational load), and a built-in clutch (limiting at 60 in*oz, but easily "locked"), and built-in mounting screw holes, you can see why we like these motors!

These units have an overall size of 55mm (2.17") x 48mm (1.89") x 23mm (0.906") thick, while only weighing 37grams or 1.31ounces.

Based on the original design by Mark Tilden for use in the B.I.O.Bugs & RoboSapien, These motors are the next generation with a variety of improvements such as dual output shafts and a lower current motor.

This particular motor is hackable from 224:1 to 14:1. Details here!
