The micro plastic gearmotor’s output shaft is compatible with our 14 mm wheels. We don’t have any brackets for this gearmotor, and it generally does not have any mounting holes, but its small size makes it simple to fasten with tape or glue. Alternatively, since this gearmotor is definitely 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 output shaft, which is 2 mm in diameter with a section that is flattened by 0.5 mm. The “D” part of the shaft is certainly 2.5 mm long. The motor Micro Planetary Gear Motor procedures 6 mm in diameter and 9 mm in length, and the gearbox duration, labeled “L” in the diagram below, depends upon the apparatus ratio. The 26:1 gearbox is usually 7.1 mm long, as the 
136:1 option actions 9.4 mm. The electric motor leads include their tips pre-stripped and extend around 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 may cause press-suit attachments like our 14 mm wheel to fit loosely occasionally. If you experience a loose fit, you could try swapping tires or using a small dab of glue to help contain the wheel on.
