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 have any mounting holes, but its compact size makes it easy to fasten with tape or glue. On the other hand, since this gearmotor can be almost the same size as a 1/4″ fuse, it could be mounted using standard 1/4″ (6 mm) fuse clips.
The following diagram shows the micro plastic gearmotor dimensions in mm. The planetary gearbox includes a D-shaped plastic output shaft, which is 2 mm in diameter with a section that is flattened by 0.5 mm. The “D” part of the shaft can be 2.5 mm long. The motor steps 6 mm in diameter and 9 mm in length, and the gearbox duration, labeled “L” in the diagram below, depends on the apparatus ratio. The 26:1 gearbox is Micro Planetary Gear Motor certainly 7.1 mm long, while the 136:1 option measures 9.4 mm. The engine leads come with their tips 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 fit loosely in some instances. If you experience a loose fitting, you could attempt swapping wheels or using a small dab of glue to help contain the wheel on.
