Overview
These tiny brushed DC gearmotors have got a diameter of just 6 mm and weigh simply over a gram, making them great actuators for miniature robots and very small mechanisms. They consist of a coreless engine fastened to a planetary gearbox by a small clip. The gears are manufactured from liquid crystal polymers (LCPs), and gearbox’s nylon output 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, that includes 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 quickness of 90 RPM and stall torque of 12 oz-in (900 g-cm) at 6 V
Note: Stalling or overloading gearmotors can greatly decrease their lifetimes and actually result in immediate harm. For these gearboxes, the suggested upper limit for instantaneous torque is usually 3.5 oz-in (250 g-cm); we strongly advise keeping used loads well under this limit. Stalls can also lead to rapid (potentially on the purchase of seconds) thermal damage to the motor windings and brushes; an over-all recommendation for brushed DC electric motor procedure is 25% or less of the stall current.
The intended nominal operating voltage for these motors is 3 V to 6 V, though in general, 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 might not be practical, and higher voltages could start negatively impacting the life span of the motor. When operating at 3 V, the free-run speed, stall torque, and stall current will all be about 50 % of what they are at 6 V as these specifications scale roughly 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-fit attachments like our 14 mm wheel to fit loosely in some instances. If you experience a loose fit, you could attempt swapping wheels or using a small dab of glue to greatly help contain the wheel on.
Gearmotor dimensions
The following diagram shows the micro plastic gearmotor dimensions in mm. The planetary gearbox includes a D-shaped plastic result shaft, which is 2 mm in diameter with a section that is flattened by 0.5 mm. The “D” part of the shaft is usually 2.5 mm long. The electric motor measures 6 mm in diameter and 9.3 mm in length, and the gearbox length, 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 much better resolution. Its 4 mm output shaft makes it compatible with plenty of ep mounts and component, which includes clamping hubs, Planetary electric motor mounts, as well as 4 mm toothed wheels and pinion gears.

Spur Equipment vs. Planetary Gear
The two the majority of common setup of DC engine gearbox are spur and planetary. Spur type gearbox are simpler, less expensive, 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, on the other hand, share equal load over multiple gears, making them more durable for high torque software.
