Overview
These tiny brushed DC gearmotors have 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 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 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 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 rate of 90 RPM and stall torque of 12 oz-in (900 g-cm) in 6 V
Notice: Stalling or overloading gearmotors may greatly decrease their lifetimes and actually result in immediate damage. For these gearboxes, the suggested higher limit for instantaneous torque can be 3.5 oz-in (250 g-cm); we strongly advise keeping used loads well under this limit. Stalls can also lead to rapid (potentially on the order of seconds) thermal damage to the engine windings and brushes; an over-all recommendation for brushed DC electric motor operation is 25% or 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 may not be practical, and higher voltages could begin negatively influencing the life of the electric motor. When operating at 3 V, 
the free-run speed, stall torque, and stall current will all be approximately half 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 might cause press-suit attachments like our 14 mm wheel to match loosely occasionally. If you experience a loose fit, you could attempt swapping wheels or using a little dab of glue to greatly help hold the wheel on.
Gearmotor dimensions
The next 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 usually 2.5 mm long. The engine procedures 6 mm in diameter and 9.3 mm in length, and the gearbox duration, labeled “L” in the diagram below, depends upon the gear ratio.
26 RPM Planetary Gear Motor with encoder: compatibility
This small 12V motor has a magnetic encoder mounted prior to the gearbox for a better resolution. Its 4 mm output shaft helps it be compatible with lots of ep mounts and component, which includes clamping hubs, Planetary engine mounts, in addition to 4 mm toothed wheels and pinion gears.

Spur Equipment vs. Planetary Gear
The two the majority of common setup of DC engine gearbox are spur and planetary. Spur type gearbox are simpler, less expensive, and work greatest for low torque applications. Torque capacity of spur type gearbox is bound because each gear in the teach bears different load. Planetary gearboxes, on the other hand, share equivalent load over multiple gears, making them stronger for high torque application.
