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

The next diagram shows the micro plastic gearmotor dimensions in mm. The planetary gearbox includes a D-shaped plastic result shaft, which is 2 mm in diameter with a section that is flattened by 0.5 mm. The “D” part of the shaft is definitely 2.5 mm long. The electric motor procedures 6 mm in diameter and 9 mm long, and the gearbox size, labeled “L” in the diagram below, depends upon the gear ratio. The 26:1 gearbox is definitely 7.1 mm long, as the 136:1 option actions 9.4 mm. The engine leads come with their suggestions pre-stripped and extend approximately 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 may cause press-suit attachments like our 14 mm wheel to match loosely occasionally. If you experience a loose fitting, you could try swapping wheels or using a small dab of glue to greatly help hold the wheel on.
