The micro plastic gearmotor’s output shaft works with with this 14 mm wheels. We don’t have any brackets for this gearmotor, and it generally does not possess any mounting holes, but its small size makes it easy to fasten with tape or glue. Alternatively, since this gearmotor is Micro Planetary Gear Motor nearly the same size as a 1/4″ fuse, it can 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 2.5 mm long. The motor procedures 6 mm in diameter and 9 mm long, and the gearbox size, labeled “L” in the diagram below, depends on the gear ratio. The 26:1 gearbox is definitely 7.1 mm long, while the 136:1 option measures 9.4 mm. The motor leads include their suggestions pre-stripped and extend approximately 2 cm (0.8″) from the back 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 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 wheels or using a small dab of glue to greatly help contain the wheel on.
