Overview
These tiny brushed DC gearmotors possess a diameter of just 6 mm and weigh just 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 manufactured from liquid crystal polymers (LCPs), and gearbox’s nylon output shaft is compatible with our 14 mm tires. Three gear ratios can be found:
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 quickness of 90 RPM and stall torque of 12 oz-in (900 g-cm) in 6 V
Take note: Stalling or overloading gearmotors can greatly decrease their lifetimes and also result in immediate harm. For these gearboxes, the recommended higher limit for instantaneous torque is certainly 3.5 oz-in (250 g-cm); we strongly advise keeping used loads well under this limit. Stalls may also lead to rapid (possibly on the purchase of seconds) thermal harm to the motor windings and brushes; a general recommendation for brushed DC engine operation is 25% or less of the stall current.
The intended nominal operating voltage for these motors is 3 V to 6 V, though in general, these types of motors can be utilized at voltages outdoors this range (rotation typically starts among 0.2 V and 0.3 V). Lower voltages might not be practical, and higher voltages could start negatively impacting the life span of the engine. When operating at 3 V, the free-run quickness, 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 might cause press-fit attachments like our 14 mm wheel to match loosely occasionally. If you experience a loose fitting, you could try swapping tires or using a small dab of glue to help contain the wheel on.
Gearmotor dimensions
The next 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’s flattened by 0.5 mm. The “D” part of the shaft is 2.5 mm long. The electric motor procedures 6 mm in diameter and 9.3 mm in length, and the gearbox duration, labeled “L” in the diagram below, depends on 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 better resolution. Its 4 mm output shaft makes it compatible with plenty of ep mounts and component, including clamping hubs, Planetary motor mounts, in addition to 4 mm toothed tires and pinion gears.

Spur Gear vs. Planetary Gear
The two the majority of common setup of DC engine 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 bound because each gear in the teach bears different load. Planetary gearboxes, in contrast, share equal load over multiple gears, making them stronger for high torque program.
