micro planetary gear motor

The micro plastic gearmotor’s output shaft works with with our 14 mm wheels. We don’t have any brackets for this gearmotor, and it does not have any installation holes, but its small size makes it simple to fasten with tape or glue. Additionally, 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 following diagram shows the micro plastic gearmotor dimensions in mm. The planetary gearbox includes a D-shaped plastic result shaft, which is 2 mm in diameter with a section that’s flattened by 0.5 mm. The “D” part of the shaft is usually 2.5 mm long. The motor actions 6 mm in diameter and 9 mm long, and the gearbox length, labeled “L” in the diagram below, depends upon the gear ratio. The 26:1 gearbox is definitely 7.1 mm long, while the 136:1 option steps 9.4 mm. The electric motor leads include their ideas pre-stripped and Micro Planetary Gear Motor extend approximately 2 cm (0.8″) from the trunk 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 might cause press-fit attachments like our 14 mm wheel to match loosely occasionally. If you experience a loose fit, you could try swapping tires or using a little dab of glue to greatly help contain the wheel on.
