The micro plastic gearmotor’s output shaft works with with this 14 mm wheels. We do not have any brackets for this gearmotor, and it does not possess any mounting holes, but its small size makes it easy to fasten with tape or glue. Additionally, since this gearmotor is nearly the same size as a 1/4″ fuse, it could be Micro Planetary Gear Motor mounted using standard 1/4″ (6 mm) fuse clips.

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

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-suit attachments like our 14 mm wheel to match loosely occasionally. In the event that you experience a loose fitting, you could try swapping tires or using a small dab of glue to greatly help hold the wheel on.
