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 does not have any mounting holes, but its compact size makes it easy to fasten with tape or glue. Additionally, since this gearmotor is certainly almost 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 Micro Planetary Gear Motor dimensions in mm. The planetary gearbox has a D-shaped plastic result shaft, which is 2 mm in diameter with a section that is flattened by 0.5 mm. The “D” portion of the shaft is certainly 2.5 mm long. The electric motor measures 6 mm in diameter and 9 mm long, and the gearbox duration, labeled “L” in the diagram below, depends on the gear ratio. The 26:1 gearbox is certainly 7.1 mm long, as the 136:1 option actions 9.4 mm. The engine leads come with their suggestions pre-stripped and extend around 2 cm (0.8″) from the back of the motor.

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-fit attachments like our 14 mm wheel to match loosely in some instances. If you experience a loose fit, you could try swapping wheels or using a small dab of glue to greatly help contain the wheel on.
