The micro plastic gearmotor’s output shaft works with with this 14 mm wheels. We don’t have any brackets for this gearmotor, and it does not possess any installation holes, but its compact size makes it simple to fasten with tape or glue. Additionally, since this gearmotor is almost the same size as a 1/4″ fuse, it can be mounted using regular 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 Micro Planetary Gear Motor result shaft, which is 2 mm in diameter with a section that’s flattened by 0.5 mm. The “D” part of the shaft is 2.5 mm long. The motor steps 6 mm in diameter and 9 mm in length, 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, while the 136:1 option measures 9.4 mm. The engine leads come with their tips pre-stripped and extend approximately 2 cm (0.8″) from the trunk 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-match attachments like our 14 mm wheel to match loosely occasionally. If you experience a loose fit, you could try swapping tires or using a little dab of glue to help hold the wheel on.
