The micro plastic gearmotor’s output shaft works with with this 14 mm wheels. We don’t have any brackets because of this gearmotor, and it does not possess any mounting holes, but its small size makes it easy to fasten with tape or glue. Additionally, 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 result shaft, which is 2 mm in diameter with a section that is flattened by 0.5 mm. The “D” part of the shaft is certainly 2.5 mm long. The engine actions 6 mm in diameter and 9 mm in length, and the gearbox length, labeled “L” in the diagram below, depends upon the apparatus ratio. The 26:1 gearbox is usually 7.1 mm long, as the 136:1 option measures 9.4 mm. The electric motor leads come with their ideas pre-stripped and extend around 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-suit Micro Planetary Gear Motor attachments like our 14 mm wheel to match loosely in some instances. If you experience a loose fitting, you could attempt swapping tires or using a small dab of glue to help contain the wheel on.
