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 electric motor fastened to a planetary gearbox by a little 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, which has 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
Notice: 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 usually 3.5 oz-in (250 g-cm); we strongly advise keeping applied loads well under this limit. Stalls can also lead to rapid (possibly on the purchase of seconds) thermal harm to the 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 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 begin negatively impacting the life of the electric motor. When operating at 3 V, the free-run rate, stall torque, and stall current will all end up being approximately half of what they are in 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-fit attachments like our 14 mm wheel to match loosely in some instances. If you experience a loose fitting, you could attempt swapping tires or using a small dab of glue to help contain the wheel on.
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 is flattened by 0.5 mm. The “D” part of the shaft can be 2.5 mm long. The engine actions 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 lots of ep mounts and part, including clamping hubs, Planetary electric motor mounts, and also 4 mm toothed wheels 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 costly, and work best for low torque applications. Torque capacity of spur type gearbox is limited because each gear in the teach bears different load. Planetary gearboxes, on the other hand, share equal load over multiple gears, making them stronger for high torque application.
