The micro plastic gearmotor’s output shaft is compatible with this 14 mm wheels. We don’t have any brackets because of this gearmotor, and it generally does not possess any installation holes, but its small size makes it simple to fasten with tape or glue. Alternatively, since this gearmotor can be almost the same size as a 1/4″ fuse, it could be mounted using regular 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 Micro Planetary Gear Motor result shaft, which is 2 mm in diameter with a section that’s flattened by 0.5 mm. The “D” portion of the shaft can be 2.5 mm long. The electric motor measures 6 mm in diameter and 9 mm in length, and the gearbox duration, labeled “L” in the diagram below, depends on the gear ratio. The 26:1 gearbox is definitely 7.1 mm long, while the 136:1 option measures 9.4 mm. The engine leads include their suggestions pre-stripped and extend around 2 cm (0.8″) from the back of the motor.
Gearmotor dimensions
Because the gearmotor’s output shaft is nylon, there may be small variances in the diameter from unit to unit. These variations might cause press-suit attachments like our 14 mm wheel to fit loosely in some instances. If you experience a 
loose fit, you could try swapping tires or using a small dab of glue to greatly help hold the wheel on.
