Overview
These tiny brushed DC gearmotors possess a diameter of just 6 mm and weigh just over a gram, which makes them great actuators for miniature robots and incredibly small mechanisms. They contain a coreless electric motor fastened to a planetary gearbox by a little clip. The gears are made from liquid crystal polymers (LCPs), and gearbox’s nylon output shaft is compatible with our 14 mm tires. Three gear ratios can be found:
26:1, that includes a free run speed of 2500 RPM and stall torque of 1 1.5 oz-in (110 g-cm) at 6 V
136:1, that includes 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 quickness of 90 RPM and stall torque of 12 oz-in (900 g-cm) at 6 V
Notice: Stalling or overloading gearmotors may greatly reduce their lifetimes and even result in immediate harm. For these gearboxes, the recommended upper limit for instantaneous torque is certainly 3.5 oz-in (250 g-cm); we strongly advise keeping used loads well under this limit. Stalls may also lead to rapid (potentially on the purchase of seconds) thermal harm to the electric motor windings and brushes; a general recommendation for brushed DC electric motor operation is 25% or much less of the stall current.
The intended nominal operating voltage for these motors is 3 V to 6 V, though in general, these kinds of motors can be used at voltages outside this range (rotation typically starts among 0.2 V and 0.3 V). Lower voltages may not be practical, and higher voltages could start negatively affecting the life span of the engine. When operating at 3 V, the free-run velocity, stall torque, and stall current will all be about 50 % of what they are at 6 V as these specifications scale roughly linearly with voltage.
Because the gearmotor’s output shaft is nylon, there can be small variances in the diameter from unit to unit. These variations may cause press-fit attachments like our 14 mm wheel to fit loosely in some instances. In the event that you experience a loose fitting, you could attempt swapping tires or using a small dab of glue to greatly help contain the wheel on.
Gearmotor dimensions
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 can be 2.5 mm long. The engine steps 6 mm in diameter and 9.3 mm long, and the gearbox duration, labeled “L” in the diagram below, depends on the gear ratio.
26 RPM Planetary Equipment Motor with encoder: compatibility
This small 12V motor comes with a magnetic encoder mounted before the gearbox for a better resolution. Its 4 mm output shaft helps it be compatible with lots of ep mounts and component, which includes clamping hubs, Planetary motor mounts, and also 4 mm toothed tires and pinion gears.

Spur Gear vs. Planetary Gear
The two most common setup of DC engine gearbox are spur and planetary. Spur type gearbox are simpler, less expensive, and work best for low torque applications. Torque capability of spur type gearbox is bound because each gear in the train bears different load. Planetary gearboxes, in contrast, share the same load over multiple gears, making them more durable for high torque app.
