The micro plastic gearmotor’s output shaft works with with this 14 mm wheels. We do not have any brackets because of this gearmotor, and it generally does not have any mounting holes, but its small size makes it easy to fasten with tape or glue. On the other hand, since this gearmotor is definitely nearly 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 includes a D-shaped plastic output shaft, which is 2 mm in diameter with a section that’s flattened by 0.5 mm. The “D” part of the shaft is certainly 2.5 mm long. The electric motor steps 6 mm in diameter and 9 mm long, and the gearbox length, 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 procedures 9.4 mm. The motor leads include their tips pre-stripped and extend around 2 cm (0.8″) from the trunk of the motor.
Since the gearmotor’s output shaft is nylon, there may be small variances in the diameter from unit to unit. These variations might cause press-match attachments like our 14 mm wheel to match loosely occasionally. If you experience a loose fit, you could try swapping wheels or using a small dab of glue to help hold the wheel on.
