The micro Micro Planetary Gear Motor plastic gearmotor’s output shaft is compatible with this 14 mm wheels. We don’t have any brackets because of this gearmotor, and it does not possess any installation holes, but its compact size makes it simple to fasten with tape or glue. Alternatively, since this gearmotor is nearly the same size as a 1/4″ fuse, it can be mounted using standard 1/4″ (6 mm) fuse clips.

The following diagram shows the micro plastic gearmotor dimensions in mm. The planetary gearbox has a D-shaped plastic result shaft, which is 2 mm in diameter with a section that’s flattened by 0.5 mm. The “D” part of the shaft can be 2.5 mm long. The motor measures 6 mm in diameter and 9 mm long, and the gearbox size, labeled “L” in the diagram below, depends upon the apparatus ratio. The 26:1 gearbox is definitely 7.1 mm long, as the 136:1 option steps 9.4 mm. The motor leads come with their guidelines pre-stripped and extend approximately 2 cm (0.8″) from the back of the motor.

Gearmotor dimensions

Since the gearmotor’s output shaft is nylon, there may be small variances in the diameter from unit to unit. These variations may cause press-fit attachments like our 14 mm wheel to fit loosely in some instances. In the event that you experience a loose fit, you could try swapping tires or using a small dab of glue to help hold the wheel on.
