Overview
These tiny brushed DC gearmotors possess a diameter of simply 6 mm and weigh just over a gram, which makes them great actuators for miniature robots and very small mechanisms. They contain a coreless engine 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 wheels. Three gear ratios are available:
26:1, which has 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 quickness 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 actually result in immediate harm. For these gearboxes, the suggested higher limit for instantaneous torque is 3.5 oz-in (250 g-cm); we strongly advise keeping used loads well under this limit. Stalls can also lead to rapid (possibly on the order of seconds) thermal harm to the electric motor windings and brushes; a general recommendation for brushed DC electric 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 in general, these types of motors can be used at voltages outdoors this range (rotation typically starts among 0.2 V and 0.3 V). Lower voltages might not be practical, and higher voltages could begin negatively affecting the life of the 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.
Because the gearmotor’s output shaft is nylon, there can 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. In the event that you experience a loose fit, you could attempt swapping tires or using a small 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 result shaft, which is 2 mm in diameter with a section that is flattened by 0.5 mm. The “D” portion of the shaft is 2.5 mm long. The motor actions 6 mm in diameter and 9.3 mm long, and the gearbox size, 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 before the gearbox for a better resolution. Its 4 mm output shaft helps it be compatible with plenty of ep mounts and part, including clamping hubs, Planetary electric motor mounts, in addition to 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 expensive, and work best for low torque applications. Torque capability of spur type gearbox is bound because each gear in the teach bears different load. Planetary gearboxes, on the other hand, share the same load over multiple gears, making them stronger for high torque software.
