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 motor fastened to a planetary gearbox by a little clip. The gears are made from liquid crystal polymers (LCPs), and gearbox’s nylon output shaft is compatible with this 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, that includes a free run acceleration of 90 RPM and stall torque of 12 oz-in (900 g-cm) in 6 V
Notice: 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 damage to the engine windings and brushes; an over-all recommendation for brushed DC engine procedure 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 utilized at voltages outside this range (rotation typically starts between 0.2 V and 0.3 V). Lower voltages may not be practical, and higher voltages could start negatively influencing the life of the engine. When operating at 3 V, the free-run rate, stall torque, and stall current will all become about 50 % of what they are at 6 V as these specifications scale approximately 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 may cause press-fit attachments like our 14 mm wheel to match loosely in some instances. If you experience a loose fitting, you could try swapping wheels or using a little dab of glue to 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 output shaft, which is 2 mm in diameter with a section that is flattened by 0.5 mm. The “D” portion of the shaft can be 2.5 mm long. The motor measures 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 makes it compatible with plenty of ep mounts and component, including clamping hubs, Planetary engine mounts, along with 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 capacity of spur type gearbox is limited because each gear in the train bears different load. Planetary gearboxes, in contrast, share equivalent load over multiple gears, making them more durable for high torque app.
