Overview
These tiny brushed DC gearmotors have got a diameter of simply 6 mm and weigh simply over a gram, making them great actuators for miniature robots and incredibly small mechanisms. They contain a coreless motor fastened to a planetary gearbox by a small 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, 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 rate of 90 RPM and stall torque of 12 oz-in (900 g-cm) at 6 V
Take note: Stalling or overloading gearmotors may greatly reduce their lifetimes and even result in immediate harm. For these gearboxes, the suggested higher 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; 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 types of motors can be utilized at voltages outdoors this range (rotation typically starts between 0.2 V and 0.3 V). Lower voltages may not be practical, and higher voltages could begin negatively affecting the life of the motor. When operating at 3 V, the free-run velocity, stall torque, and stall current will all become 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-fit attachments like our 14 mm wheel to fit loosely occasionally. If you experience a loose fit, you could try swapping wheels or using a little dab of glue to greatly help contain 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’s flattened by 0.5 mm. The “D” part of the shaft is 2.5 mm long. The electric motor actions 6 mm in diameter and 9.3 mm long, and the gearbox duration, labeled “L” in the diagram below, depends upon the gear ratio.
26 RPM Planetary Equipment Motor with encoder: compatibility
This small 12V motor comes with 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, including clamping hubs, Planetary electric motor mounts, along with 4 mm toothed wheels and pinion gears.

Spur Equipment vs. Planetary Gear
The two many common setup of DC 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 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 software.
