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 mounting holes, but its compact size makes it simple to fasten with tape or glue. Additionally, since this gearmotor is certainly nearly the same size as a 1/4″ fuse, it can 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 engine actions 6 mm in diameter and 9 mm in length, and the gearbox length, labeled “L” in the diagram below, depends on the apparatus ratio. The 26:1 gearbox is 7.1 mm long, while the 136:1 option steps 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
Since the gearmotor’s output shaft is nylon, there can be small variances in the diameter from unit to unit. These variations might cause press-match Micro Planetary Gear Motor attachments like our 14 mm wheel to fit loosely in some instances. In the event that you experience a loose fitting, you could try swapping tires or using a little dab of glue to help contain the wheel on.
