The micro plastic gearmotor's output shaft is compatible with our 14 mm wheels. We don't have any brackets for this gearmotor, and it generally does not Micro Planetary Gear Motor possess any mounting 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 can be mounted using standard 1/4″ (6 mm) fuse clips.

The following diagram shows the micro plastic gearmotor dimensions in mm. The planetary gearbox has a D-shaped plastic result shaft, which is 2 mm in diameter with a section that's flattened by 0.5 mm. The “D” part of the shaft is 2.5 mm long. The motor steps 6 mm in diameter and 9 mm long, and the gearbox duration, labeled “L” in the diagram below, depends on the apparatus ratio. The 26:1 gearbox is usually 7.1 mm long, as the 136:1 option steps 9.4 mm. The engine leads include their guidelines 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 might cause press-suit attachments like our 14 mm wheel to match loosely in some instances. If you experience a loose fitting, you could attempt swapping wheels or using a little dab of glue to help hold the wheel on.
