Gear Motor 2: Offset Shaft from Tinkering Supplies



This 224:1 gearmotor is very comparable to a hobby servo for power, at a fraction of the cost!

This motor offers 50 in-oz of torque and rotates at 38 rpm (just a bit slower than a servo). With a 5V power source it draws 600mA when stalled and 52ma when unloaded. It has a 7mm double-flat output shaft, built-in clutch, and convenient mounting screw holes.

These units have an overall size of 55mm (2.17") x 47mm (1.85") x 22mm (0.87") thick. They are based on a design by Mark Tilden for use in the B.I.O.-Bugs but with with a variety of improvements such as dual output shafts and a lower current motor.

The motor does not include 30mm Plastic Wheel for GM Axle shown in the photo. Catalog number: 1208. Brand: Tinkering Supplies. Brand's Part Number: 1208.

Gear Motor 3: Right Angle Shaft from Tinkering Supplies



This is is essentially the same as Gear Motor 2 but with a 90 degree output shaft.

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!

Overall dimensions are 65mm (2.56") long x 22mm (0.867") x 18.5mm (0.73").

The motor does not include 30mm Plastic Wheel for GM Axle shown in the photo. Catalog number: 1209. Brand: Tinkering Supplies. Brand's Part Number: 1209.

Motor: Gear Motor Performance Upgrade from Tinkering Supplies



A high power motor that fits in the same form factor as used by the GM2/GM3/GM8/GM9 style gear motors. When retrofitted (an easy process after removing the GM2/3/8/9 motor strap), it nearly triples the output speed and doubles the torque!

Be forewarned - the increase in power output comes with an suitable increase in power consumption! When used in a GM2/3/8/9, the power output is considerably higher.

The motor has an 0.08" (2mm) output shaft. The main can body dimensions are 0.6" x 0.8" x 1" (15mm x 20mm x 25mm). The length including the front and rear alignment pads is 1.15" (29mm) and the overall length including the output shaft is 1.5" (38mm). Catalog number: 1205. Brand: Tinkering Supplies.
