These tiny brushed DC gearmotors possess a diameter of simply 6 mm and weigh just over a gram, which makes them great actuators for miniature robots and incredibly 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 our 14 mm wheels. 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 also result in immediate damage. For these gearboxes, the suggested top limit for instantaneous torque is definitely 3.5 oz-in (250 g-cm); we strongly advise keeping used loads well under this limit. Stalls can also result in rapid (possibly on the purchase of seconds) thermal damage to the engine windings and brushes; a general 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 in general, these kinds 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 useful, and higher voltages could start negatively influencing the life of the engine. When operating at 3 V, the free-run acceleration, stall torque, and stall current will all end up being approximately half of what they are in 6 V as these specifications scale approximately 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 match loosely occasionally. In the event that you experience a loose fit, you could try swapping tires or using a small dab of glue to help contain the wheel on.
The following diagram shows the micro plastic gearmotor dimensions in mm. The planetary gearbox has 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 can be 2.5 mm long. The engine actions 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 comes with a magnetic encoder mounted before the gearbox for a much better resolution. Its 4 mm output shaft helps it be compatible with plenty of ep mounts and component, including clamping hubs, Planetary motor mounts, as well as 4 mm toothed tires and pinion gears.

Spur Equipment 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 capability of spur type gearbox is limited because each gear in the teach bears different load. Planetary gearboxes, in contrast, share equivalent load over multiple gears, making them stronger for high torque app.
