The micro plastic gearmotor’s output shaft is compatible with our 14 mm wheels. We do not have any brackets because of this gearmotor, and it generally does not possess any mounting holes, but its small size makes it simple to fasten with tape or glue. Alternatively, since this gearmotor is nearly the same size as a 1/4″ fuse, it can be mounted using standard 1/4″ (6 mm) fuse clips.

The next diagram shows the micro plastic gearmotor dimensions in mm. The planetary gearbox has a D-shaped plastic result shaft, which is 2 mm in Micro Planetary Gear Motor diameter with a section that’s flattened by 0.5 mm. The “D” portion of the shaft is usually 2.5 mm long. The engine procedures 6 mm in diameter and 9 mm long, and the gearbox size, labeled “L” in the diagram below, depends upon the gear ratio. The 26:1 gearbox is usually 7.1 mm long, as the 136:1 option steps 9.4 mm. The electric motor leads include their ideas pre-stripped and extend approximately 2 cm (0.8″) from the trunk of the motor.

Gearmotor dimensions

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 try swapping wheels or using a small dab of glue to help contain the wheel on.
