Overview
These tiny brushed DC gearmotors have a diameter of just 6 mm and weigh just over a gram, making them great actuators for miniature robots and very small mechanisms. They contain a coreless electric motor fastened to a planetary gearbox by a small 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, which has a free run speed of 2500 RPM and stall torque of 1 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 acceleration of 90 RPM and stall torque of 12 oz-in (900 g-cm) in 6 V
Notice: Stalling or overloading gearmotors may greatly reduce their lifetimes and actually result in immediate harm. For these gearboxes, the recommended top limit for instantaneous torque is certainly 3.5 oz-in (250 g-cm); we highly advise keeping used loads well under this limit. Stalls can also result in rapid (possibly on the purchase of seconds) thermal damage 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 types of motors can be utilized at voltages outdoors 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 affecting the life of the engine. 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 may be small variances in the diameter from unit to unit. These variations may cause press-match attachments like our 14 mm wheel to match loosely occasionally. If you experience a loose fitting, you could attempt swapping wheels or using a little dab of glue to 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 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 motor steps 6 mm in diameter and 9.3 mm long, and the gearbox size, labeled “L” in the diagram below, depends upon the gear ratio.
26 RPM Planetary Equipment 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 helps it be compatible with plenty of ep mounts and part, which includes clamping hubs, Planetary motor mounts, along with 4 mm toothed tires and pinion gears.

Spur Gear vs. Planetary Gear
The two many common setup of DC electric motor gearbox are spur and planetary. Spur type gearbox are simpler, less costly, and work greatest for low torque applications. Torque capability of spur type gearbox is limited 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 app.
