These tiny brushed DC gearmotors possess a diameter of simply 6 mm and weigh just over a gram, making them great actuators for miniature robots and incredibly small mechanisms. They contain a coreless electric motor fastened to a planetary gearbox by a little clip. The gears are manufactured 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, 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, which has a free run speed of 90 RPM and stall torque of 12 oz-in (900 g-cm) at 6 V
Notice: Stalling or overloading gearmotors may greatly decrease their lifetimes and even result in immediate harm. For these gearboxes, the recommended upper 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 order of seconds) thermal harm 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 generally, these types of motors can be used at voltages outdoors this range (rotation typically starts between 0.2 V and 0.3 V). Lower voltages is probably not useful, and higher voltages could start negatively impacting the life span of the motor. When operating at 3 V, the free-run quickness, stall torque, and stall current will all end up being approximately half of what they are at 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 fit loosely in some instances. If you experience a loose fit, you could try swapping wheels or using a little dab of glue to help contain the wheel on.
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’s flattened by 0.5 mm. The “D” portion of the shaft is 2.5 mm long. The motor steps 6 mm in diameter and 9.3 mm in length, and the gearbox size, 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 much better resolution. Its 4 mm output shaft helps it be compatible with plenty of ep mounts and part, including clamping hubs, Planetary motor mounts, as well as 4 mm toothed tires and pinion gears.

Spur Equipment vs. Planetary Gear
The two many common setup of DC motor gearbox are spur and planetary. Spur type gearbox are simpler, less expensive, and work best for low torque applications. Torque capability of spur type gearbox is limited because each equipment in the teach bears different load. Planetary gearboxes, on the other hand, share equal load over multiple gears, making them stronger for high torque software.
