The micro plastic gearmotor’s Micro Planetary Gear Motor output shaft is compatible with our 14 mm wheels. We do not have any brackets for this gearmotor, and it generally does not have any mounting holes, but its compact size makes it easy to fasten with tape or glue. On the other hand, since this gearmotor is certainly nearly the same size as a 1/4″ fuse, it could be mounted using regular 1/4″ (6 mm) fuse clips.
The next 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” portion of the shaft is 2.5 mm long. The motor procedures 6 mm in diameter and 9 mm in length, and the gearbox length, labeled “L” in the diagram below, depends on the apparatus ratio. The 26:1 gearbox is definitely 7.1 mm long, while the 136:1 option procedures 9.4 mm. The engine leads come with their ideas pre-stripped and extend around 2 cm (0.8″) from the back of the motor.
Since 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 match loosely occasionally. If you experience a loose fit, you could attempt swapping wheels or using a little dab of glue to help contain the wheel on.
