Overview
These tiny brushed DC gearmotors have 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 electric motor fastened to a planetary gearbox by a small clip. The gears are manufactured from liquid crystal polymers (LCPs), and gearbox’s nylon result shaft is compatible with our 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 swiftness of 90 RPM and stall torque of 12 oz-in (900 g-cm) in 6 V
Notice: Stalling or overloading gearmotors may greatly reduce their lifetimes and even result in immediate damage. For these gearboxes, the recommended upper limit for instantaneous torque is definitely 3.5 oz-in (250 g-cm); we highly advise keeping used loads well under this limit. Stalls can also result in rapid (potentially on the order of seconds) thermal damage to the motor windings and brushes; a general recommendation for brushed DC 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 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 useful, and higher voltages could start negatively influencing the life span of the engine. When operating at 3 V, the free-run quickness, stall torque, and stall current will all be approximately half of what they are at 6 V as these specifications scale roughly 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-match attachments like our 14 mm wheel to fit 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 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” part of the shaft is certainly 2.5 mm long. The electric motor steps 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 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 part, including clamping hubs, Planetary motor mounts, as well as 4 mm toothed wheels 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 expensive, 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, in contrast, share equivalent load over multiple gears, making them more durable for high torque program.
