  DC Gearmotor and Mount -- Single Motor

This small and affordable DC gearmotor comes with its own 2" diameter wheel. The wheel has a 1/2" wide rubber tire for terrific traction. We supply a universal mount, with hardware, so that you can attach the motor to your own robotic base.

The motor is shown here with optional aluminum stadoffs. You can attach the motor mount directly to your robot, or with standoffs -- the standoffs offer extra clearance should you need it for your robot design. We supply three popular lengths of metal standoffs as options.

The motor is double-shafted. On one end is the wheel; on the other is a 1/8" locking collar. There is ample room to mount a small optical wheel encoder next to the locking collar.
