micro planetary gear motor

The micro Micro Planetary Gear Motor plastic gearmotor’s output shaft works with with our 14 mm wheels. We do not have any brackets for 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 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 has a D-shaped plastic output shaft, which is 2 mm in diameter with a section that's flattened by 0.5 mm. The “D” portion of the shaft is 2.5 mm long. The engine actions 6 mm in diameter and 9 mm long, and the gearbox size, labeled “L” in the diagram below, depends upon the apparatus ratio. The 26:1 gearbox is 7.1 mm long, as the 136:1 option actions 9.4 mm. The engine leads include their ideas pre-stripped and extend around 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-match attachments like our 14 mm wheel to match loosely occasionally. If you experience a loose fit, you could attempt swapping wheels or using a small dab of glue to help contain the wheel on.
