Overview
These tiny brushed DC gearmotors have got a diameter of just 6 mm and weigh just over a gram, making them great actuators for miniature robots and very small mechanisms. They consist of a coreless electric motor 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 wheels. Three gear ratios can be found:
26:1, that includes 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, that includes 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 swiftness 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 even result in immediate damage. For these gearboxes, the suggested higher limit for instantaneous torque is definitely 3.5 oz-in (250 g-cm); we highly advise keeping applied loads well under this limit. Stalls may also lead to rapid (potentially on the order of seconds) thermal damage to the engine windings and brushes; an over-all recommendation for brushed DC electric motor 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 practical, and higher voltages could start negatively affecting the life of the electric motor. When operating at 3 V, the free-run quickness, stall torque, and stall current will all end up being about 50 % of what they are in 6 V as these specifications scale approximately 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 occasionally. If you experience a loose fit, you could try swapping wheels or using a little dab of glue to help hold the wheel on.
Gearmotor dimensions
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 can be 2.5 mm long. The motor actions 6 mm in diameter and 9.3 mm long, 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 includes a magnetic encoder mounted before the gearbox for a much better resolution. Its 4 mm output shaft makes it compatible with lots of ep mounts and part, including clamping hubs, Planetary engine mounts, in addition to 4 mm toothed wheels and pinion gears.

Spur Equipment vs. Planetary Gear
The two many common setup of DC motor gearbox are spur and planetary. Spur type gearbox are simpler, less costly, and work greatest 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 application.
