Overview
These tiny brushed DC gearmotors possess a diameter of simply 6 mm and weigh just over a gram, which makes them great actuators for miniature robots and very small mechanisms. They contain a coreless electric motor fastened to a planetary gearbox by a little clip. The gears are manufactured from liquid crystal polymers (LCPs), and gearbox’s nylon output shaft is compatible with our 14 mm wheels. Three gear ratios can be found:
26:1, that includes a free run speed of 2500 RPM and stall torque of just one 1.5 oz-in (110 g-cm) at 6 V
136:1, which has a free run speed of 500 RPM and stall torque of 8 oz-in (550 g-cm) at 6 V
700:1, that includes a free run swiftness of 90 RPM and stall torque of 12 oz-in (900 g-cm) in 6 V
Take note: Stalling or overloading gearmotors may greatly reduce their lifetimes and even result in immediate damage. For these gearboxes, the suggested upper limit for instantaneous torque is usually 3.5 oz-in (250 g-cm); we highly advise keeping applied loads well under this limit. Stalls may also result in rapid (possibly on the order of seconds) thermal harm to the electric motor windings and brushes; an over-all recommendation for brushed DC motor procedure is 25% or less of the stall current.
The intended nominal operating voltage for these motors is 3 V to 6 V, though generally, these kinds of motors can be used at voltages outside this range (rotation typically starts between 0.2 V and 0.3 V). Lower voltages is probably not useful, and higher voltages could start negatively affecting the life of the electric motor. When operating at 3 V, the free-run acceleration, stall torque, and stall current will all be approximately half of what they are in 6 V as these specifications scale approximately linearly with voltage.
Since the gearmotor’s output shaft is nylon, there may be small variances in the diameter from unit to unit. These variations might cause press-suit attachments like our 14 mm wheel to match loosely occasionally. If you experience a loose fitting, you could attempt swapping tires or using a little dab of glue to help contain the wheel on.
Gearmotor dimensions
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’s flattened by 0.5 mm. The “D” part of the shaft is 2.5 mm long. The electric motor steps 6 mm in diameter and 9.3 mm in length, and the gearbox duration, labeled “L” in the diagram below, depends upon the gear ratio.
26 RPM Planetary Gear Motor with encoder: compatibility
This small 12V motor includes a magnetic encoder mounted prior to the gearbox for a better resolution. Its 4 mm output shaft makes it compatible with plenty of ep mounts and component, which includes clamping hubs, Planetary engine mounts, as well as 4 mm toothed wheels and pinion gears.

Spur Gear vs. Planetary Gear
The two the majority of common setup of DC motor gearbox are spur and planetary. Spur type gearbox are simpler, less expensive, and work best for low torque applications. Torque capacity of spur type gearbox is bound because each equipment in the teach bears different load. Planetary gearboxes, in contrast, share the same load over multiple gears, making them stronger for high torque application.
