The micro plastic gearmotor’s output shaft is compatible with this 14 mm wheels. We don’t have any Micro Planetary Gear Motor brackets for this gearmotor, and it does not possess any installation holes, but its small size makes it simple to fasten with tape or glue. Alternatively, since this gearmotor is definitely almost 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 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 usually 2.5 mm long. The engine steps 6 mm in diameter and 9 mm in length, and the gearbox size, labeled “L” in the diagram below, depends on the gear ratio. The 26:1 gearbox is 7.1 mm long, as the 136:1 option measures 9.4 mm. The motor leads come with their suggestions pre-stripped and extend approximately 2 cm (0.8″) from the back of the motor.
Because the gearmotor’s output shaft is nylon, there can be small variances in the diameter from unit to unit. These variations might cause press-fit attachments like our 14 mm wheel to fit loosely in some instances. If you experience a loose fit, you could attempt swapping tires or using a small dab of glue to greatly help contain the wheel on.
