Overview
These tiny brushed DC gearmotors possess a diameter of simply 6 mm and weigh just over a gram, making them great actuators for miniature robots and very small mechanisms. They contain a coreless motor fastened to a planetary gearbox by a small clip. The gears are made from liquid crystal polymers (LCPs), and gearbox’s nylon result shaft is compatible with our 14 mm tires. Three gear ratios are available:
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, 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 velocity 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 actually result in immediate damage. For these gearboxes, the suggested higher limit for instantaneous torque is definitely 3.5 oz-in (250 g-cm); we highly advise keeping used loads well under this limit. Stalls can also lead to rapid (possibly on the order of seconds) thermal damage to the engine windings and brushes; an over-all recommendation for brushed DC 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 generally, these kinds of motors can be used at voltages outdoors this range (rotation typically starts between 0.2 V and 0.3 V). Lower voltages is probably not practical, and higher voltages could begin negatively influencing the life span of the electric motor. When operating at 3 V, the free-run acceleration, stall torque, and stall current will all become about 50 % of what they are in 6 V as these specifications scale roughly linearly with voltage.
Because the gearmotor’s output shaft is nylon, there may be small variances in the diameter from unit to unit. These variations may cause press-match attachments like our 14 mm wheel to fit 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 hold the wheel on.
Gearmotor dimensions
The next 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 is flattened by 0.5 mm. The “D” portion of the shaft can be 2.5 mm long. The engine measures 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 Gear Motor with encoder: compatibility
This small 12V motor comes with a magnetic encoder mounted prior to the gearbox for a much better resolution. Its 4 mm output shaft makes it compatible with lots of ep mounts and part, which includes clamping hubs, Planetary motor mounts, in addition to 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 costly, and work best for low torque applications. Torque capability of spur type gearbox is bound because each equipment in the teach bears different load. Planetary gearboxes, in contrast, share equivalent load over multiple gears, making them more durable for high torque app.
