Overview
These tiny brushed DC gearmotors have got a diameter of simply 6 mm and weigh just over a gram, which makes them great actuators for miniature robots and incredibly small mechanisms. They consist of 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 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, that includes a free run speed of 500 RPM and stall torque of 8 oz-in (550 g-cm) at 6 V
700:1, which has a free run swiftness of 90 RPM and stall torque of 12 oz-in (900 g-cm) at 6 V
Take note: Stalling or overloading gearmotors can greatly decrease their lifetimes and actually result in immediate damage. For these gearboxes, the suggested top limit for instantaneous torque is usually 3.5 oz-in (250 g-cm); we highly advise keeping used loads well under this limit. Stalls can also lead to rapid (potentially on the order of seconds) thermal harm to the electric motor windings and brushes; a general recommendation for brushed DC engine operation 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 types of motors can be utilized at voltages outside this range (rotation typically starts between 0.2 V and 0.3 V). Lower voltages might not be practical, and higher voltages could start negatively impacting the life span of the motor. When operating at 3 V, the free-run acceleration, stall torque, and stall current will all end up being about 50 % of what they are at 6 V as these specifications scale roughly linearly with voltage.
Since the gearmotor's output shaft is nylon, there can be small variances in the diameter from unit to unit. These variations may cause press-suit attachments like our 14 mm wheel to match loosely in some instances. In the event that you experience a loose fit, you could attempt swapping wheels or using a small dab of glue to help hold the wheel 
on.
Gearmotor dimensions
The following 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” portion of the shaft is definitely 2.5 mm long. The electric motor steps 6 mm in diameter and 9.3 mm long, and the gearbox length, labeled “L” in the diagram below, depends upon the gear ratio.
26 RPM Planetary Gear Motor with encoder: compatibility
This small 12V motor has a magnetic encoder mounted before the gearbox for a better resolution. Its 4 mm output shaft makes it compatible with plenty of ep mounts and part, which includes clamping hubs, Planetary engine mounts, along with 4 mm toothed tires and pinion gears.

Spur Gear vs. Planetary Gear
The two the majority of common setup of DC electric motor gearbox are spur and planetary. Spur type gearbox are simpler, less expensive, and work greatest for low torque applications. Torque capacity of spur type gearbox is limited because each gear in the train bears different load. Planetary gearboxes, in contrast, share equal load over multiple gears, making them more durable for high torque software.
