The micro plastic gearmotor’s output shaft works with with our 14 mm wheels. We do not have any brackets for this gearmotor, and it generally does not have any installation holes, but its small size makes it easy to fasten with tape or glue. Additionally, since this gearmotor is 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 is definitely 2.5 mm long. The engine procedures 6 mm in diameter and 9 mm in length, and the gearbox size, labeled “L” in the diagram below, Micro Planetary Gear Motor depends on the apparatus ratio. The 26:1 gearbox is 7.1 mm long, as the 136:1 option steps 9.4 mm. The engine leads come with their suggestions pre-stripped and extend around 2 cm (0.8″) from the trunk 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 fit loosely occasionally. If you experience a loose fit, you could attempt swapping tires or using a little dab of glue to help contain the wheel on.
