These are colorful wheels to attach any robot. The hubs dimension out at 65mm (just under 2-5/8"), by 7.62mm wide (0.3").
This motor offers 48.6 in*oz of torque at 3V, rotating 360 degrees every 1.5 seconds (24 rpm - just a hair slower than a servo), drawing 400mA at stall (free running at 40mA).
These precision laser-cut steel brackets match the features on the gear motor, and securely clamp them down to your project.
The GM10 Wheel works very well with the GM10 gear motor. It measures 25mm (1") in diameter, 5.7mm wide (.22"), and uses well-proven traction-band tires.
These new hard plastic wheels are specially designed for our GM2, GM3, GM8, GM9 and GM17 gear motor output shafts. Size: 3.0 x 0.7 x 3.0 cm.
