These tiny brushed DC gearmotors possess a diameter of just 6 mm and weigh just over a gram, which makes them great actuators for miniature robots and very small mechanisms. They consist of a coreless motor 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, which has 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, that includes a free run quickness of 90 RPM and stall torque of 12 oz-in (900 g-cm) in 6 V
Notice: Stalling or overloading gearmotors can greatly decrease their lifetimes and actually result in immediate damage. For these gearboxes, the recommended top limit for instantaneous torque can be 3.5 oz-in (250 g-cm); we strongly advise keeping applied loads well under this limit. Stalls can also lead to rapid (potentially on the purchase of seconds) thermal harm to the motor 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 kinds of motors can be used at voltages outside this range (rotation typically starts among 0.2 V and 0.3 V). Lower voltages is probably not useful, and higher voltages could start negatively impacting the life span of the engine. When operating at 3 V, the free-run swiftness, 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 might cause press-suit 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 small dab of glue to greatly 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” portion of the shaft is certainly 2.5 mm long. The motor measures 6 mm in diameter and 9.3 mm long, and the gearbox size, labeled “L” in the diagram below, depends upon the gear ratio.
26 RPM Planetary Gear Motor with encoder: compatibility
This small 12V motor includes a magnetic encoder mounted before the gearbox for a better resolution. Its 4 mm output shaft helps it be compatible with lots of ep mounts and component, which includes clamping hubs, Planetary engine mounts, along with 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 expensive, and work greatest for low torque applications. Torque capability of spur type gearbox is bound because each equipment in the teach bears different load. Planetary gearboxes, on the other hand, share equivalent load over multiple gears, making them stronger for high torque app.
