These tiny brushed DC gearmotors possess a diameter of just 6 mm and weigh simply over a gram, making them great actuators for miniature robots and incredibly small mechanisms. They consist of a coreless engine fastened to a planetary gearbox by a little clip. The gears are produced from liquid crystal polymers (LCPs), and gearbox’s nylon output shaft is compatible with this 14 mm tires. Three gear ratios can be found:
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 swiftness of 90 RPM and stall torque of 12 oz-in (900 g-cm) at 6 V
Take note: Stalling or overloading gearmotors can greatly reduce their lifetimes and even result in immediate harm. For these gearboxes, the suggested top limit for instantaneous torque is certainly 3.5 oz-in (250 g-cm); we highly advise keeping applied loads well under this limit. Stalls may also result in rapid (potentially on the order of seconds) thermal damage to the engine windings and brushes; an over-all 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 used at voltages outside this range (rotation typically starts among 0.2 V and 0.3 V). Lower voltages might not be practical, and higher voltages could start negatively affecting the life span of the motor. When operating at 3 V, the free-run speed, stall torque, and stall current will all be approximately half of what they are in 6 V as these specifications scale approximately 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 match loosely in some instances. If you experience a loose fitting, you could try swapping tires or using a little dab of glue to help contain 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 electric motor measures 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 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 component, including clamping hubs, Planetary electric motor mounts, as well as 4 mm toothed tires and pinion gears.

Spur Gear vs. Planetary Gear
The two the majority of common setup of DC electric motor 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 the same load over multiple gears, making them more durable for high torque application.
