The micro plastic gearmotor’s output shaft is compatible with our 14 mm wheels. We do not have any brackets because of this gearmotor, and it does not have any installation holes, but its compact size makes it easy to fasten with tape or glue. Alternatively, since this gearmotor can be nearly 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 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” portion of the shaft is certainly 2.5 mm long. The electric motor steps 6 mm in diameter and 9 mm long, and the gearbox duration, labeled “L” in the diagram below, Micro Planetary Gear Motor depends on the apparatus ratio. The 26:1 gearbox is usually 7.1 mm long, as the 136:1 option measures 9.4 mm. The engine leads come with their suggestions pre-stripped and extend approximately 2 cm (0.8″) from the trunk of the motor.

Gearmotor dimensions

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-fit attachments like our 14 mm wheel to match loosely in some instances. In the event that you experience a loose fitting, you could attempt swapping wheels or using a small dab of glue to help hold the wheel on.
