The micro plastic gearmotor’s output shaft is compatible with this 14 mm wheels. We don’t have any brackets for this gearmotor, and it does not have any mounting holes, but its small size makes it easy to fasten with tape or glue. Additionally, since this gearmotor can be almost the same size as a 1/4″ fuse, it can be mounted using regular 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 diameter with a section that is flattened by 0.5 mm. The “D” portion of the shaft is certainly 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 can be 7.1 mm long, as the 136:1 option Micro Planetary Gear Motor actions 9.4 mm. The engine leads come with their tips pre-stripped and extend approximately 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 may cause press-suit attachments like our 14 mm wheel to match loosely in some instances. If you experience a loose fitting, you could try swapping tires or using a small dab of glue to greatly help contain the wheel on.
