These tiny brushed DC gearmotors possess a diameter of just 6 mm and weigh simply over a gram, making them great actuators for miniature robots and incredibly small mechanisms. They consist of a coreless motor fastened to a planetary gearbox by a little clip. The gears are produced from liquid crystal polymers (LCPs), and gearbox’s nylon result shaft is compatible with this 14 mm wheels. Three gear ratios are available:
26:1, which has 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 acceleration 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 also result in immediate damage. For these gearboxes, the recommended top 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 result in rapid (potentially on the purchase of seconds) thermal harm to the engine windings and brushes; an over-all recommendation for brushed DC engine 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 utilized at voltages outside this range (rotation typically starts between 0.2 V and 0.3 V). Lower voltages is probably not practical, and higher voltages could start negatively influencing the life of the engine. When operating at 3 V, the free-run velocity, stall torque, and stall current will all become 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 may be small variances in the diameter from unit to unit. These variations may cause press-fit attachments like our 14 mm wheel to match loosely in some instances. In the event that you experience a loose fit, you could try swapping wheels or using a little dab of glue to help hold the wheel on.
The following diagram shows the micro plastic gearmotor dimensions in mm. The planetary gearbox has a D-shaped plastic output shaft, which is 2 mm in diameter with a section that’s flattened by 0.5 mm. The “D” portion of the shaft can be 2.5 mm long. The motor steps 6 mm in diameter and 9.3 mm in length, and the gearbox length, labeled “L” in the diagram below, depends upon the gear ratio.
26 RPM Planetary Equipment Motor with encoder: compatibility
This small 12V motor includes a magnetic encoder mounted prior to the gearbox for a much better resolution. Its 4 mm output shaft helps it be compatible with lots of ep mounts and component, including clamping hubs, Planetary engine mounts, and also 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 greatest for low torque applications. Torque capability of spur type gearbox is limited because each equipment in the train bears different load. Planetary gearboxes, in contrast, share equivalent load over multiple gears, making them stronger for high torque app.
