These tiny brushed DC gearmotors have got 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 electric motor fastened to a planetary gearbox by a small clip. The gears are made from liquid crystal polymers (LCPs), and gearbox’s nylon output shaft is compatible with this 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 rate of 90 RPM and stall torque of 12 oz-in (900 g-cm) at 6 V
Take note: Stalling or overloading gearmotors may greatly reduce their lifetimes and also result in immediate harm. For these gearboxes, the suggested top limit for instantaneous torque can be 3.5 oz-in (250 g-cm); we strongly advise keeping used loads well under this limit. Stalls may also lead to rapid (possibly on the purchase of seconds) thermal harm to the motor windings and brushes; an over-all recommendation for brushed DC engine operation is 25% or much 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 utilized at voltages outdoors this range (rotation typically starts between 0.2 V and 0.3 V). Lower voltages might not be useful, 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 become about 50 % of what they are in 6 V as these specifications scale approximately linearly with voltage.
Because the gearmotor’s output shaft is nylon, there may 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 occasionally. If you experience a loose fit, you could attempt swapping tires or using a small dab of glue to help hold the wheel on.
The following 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 definitely 2.5 mm long. The electric motor procedures 6 mm in diameter and 9.3 mm in length, 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 prior to 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 motor mounts, in addition to 4 mm toothed tires and pinion gears.

Spur Gear vs. Planetary Gear
The two most common setup of DC 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 train bears different load. Planetary gearboxes, in contrast, share equivalent load over multiple gears, making them stronger for high torque software.
