The micro plastic gearmotor’s output shaft is compatible with our 14 mm wheels. We don’t have any Micro Planetary Gear Motor brackets because of this gearmotor, and it generally does not have any mounting holes, but its compact 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 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 has a D-shaped plastic output shaft, which is 2 mm in diameter with a section that is flattened by 0.5 mm. The “D” portion of the shaft can be 2.5 mm long. The motor procedures 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 can be 7.1 mm long, while the 136:1 option procedures 9.4 mm. The engine leads come with their suggestions pre-stripped and extend around 2 cm (0.8″) from the back of the motor.
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-match attachments like our 14 mm wheel to match loosely in some instances. If you experience a loose fit, you could attempt swapping wheels or using a small dab of glue to help hold the wheel on.
