These tiny brushed DC gearmotors have a diameter of just 6 mm and weigh simply over a gram, which makes them great actuators for miniature robots and very small mechanisms. They consist of a coreless engine fastened to a planetary gearbox by a little clip. The gears are made from liquid crystal polymers (LCPs), and gearbox’s nylon result shaft is compatible with this 14 mm tires. Three gear ratios are available:
26:1, that includes 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, 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 actually result in immediate damage. For these gearboxes, the suggested upper limit for instantaneous torque can be 3.5 oz-in (250 g-cm); we strongly advise keeping used loads well under this limit. Stalls can also result in rapid (possibly on the purchase of seconds) thermal harm to the motor windings and brushes; a general recommendation for brushed DC motor 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 among 0.2 V and 0.3 V). Lower voltages may not be practical, and higher voltages could start negatively affecting the life span of the engine. When operating at 3 V, the free-run speed, stall torque, and stall current will all become approximately half 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 might 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 wheels or using a little dab of glue to greatly help hold the wheel on.
The next 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 2.5 mm long. The motor measures 6 mm in diameter and 9.3 mm in length, 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 prior to the gearbox for a much better resolution. Its 4 mm output shaft helps it be compatible with plenty of ep mounts and part, which includes clamping hubs, Planetary electric motor mounts, in addition to 4 mm toothed wheels and pinion gears.

Spur Gear vs. Planetary Gear
The two the majority of common setup of DC motor 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 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 app.
