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 incredibly small mechanisms. They contain a coreless engine fastened to a planetary gearbox by a small clip. The gears are made from liquid crystal polymers (LCPs), and gearbox’s nylon result shaft is compatible with our 14 mm wheels. Three gear ratios are available:
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, 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
Note: Stalling or overloading gearmotors can greatly decrease their lifetimes and even result in immediate damage. For these gearboxes, the recommended top limit for instantaneous torque can be 3.5 oz-in (250 g-cm); we highly advise keeping used loads well under this limit. Stalls can also result in rapid (possibly on the order of seconds) thermal harm to the motor windings and brushes; an over-all recommendation for brushed DC 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 types of motors can be used at voltages outside this range (rotation typically starts between 0.2 V and 0.3 V). Lower voltages might not be practical, and higher voltages could begin negatively impacting the life span of the engine. When operating at 3 V, the free-run speed, stall torque, and stall current will all end up being 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 in some instances. If you experience a loose fit, you could try swapping wheels or using a small dab of glue to greatly 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 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 certainly 2.5 mm long. The motor procedures 6 mm in diameter and 9.3 mm in length, and the gearbox duration, labeled “L” in the diagram below, depends upon the gear ratio.
26 RPM Planetary Gear Motor with encoder: compatibility
This small 12V motor comes with a magnetic encoder mounted before the gearbox for a better resolution. Its 4 mm output shaft makes it compatible with lots of ep mounts and component, including clamping hubs, Planetary engine mounts, in addition to 4 mm toothed tires and pinion gears.

Spur Equipment vs. Planetary Gear
The two many common setup of DC electric 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 teach bears different load. Planetary gearboxes, in contrast, share equal load over multiple gears, making them more durable for high torque app.
