Overview
These tiny brushed DC gearmotors possess a diameter of simply 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 small 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 can be found:
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, which has 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 velocity of 90 RPM and stall torque of 12 oz-in (900 g-cm) at 6 V
Notice: Stalling or overloading gearmotors can greatly reduce their lifetimes and actually result in immediate damage. For these gearboxes, the recommended top limit for instantaneous torque is usually 3.5 oz-in (250 g-cm); we strongly advise keeping applied loads well under this limit. Stalls may also result in rapid (potentially on the order of seconds) thermal harm to the motor windings and brushes; an over-all recommendation for brushed DC electric motor 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 in general, 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 might not be practical, and higher voltages could start negatively influencing the life span of the motor. When operating at 3 V, the free-run swiftness, stall torque, and stall current will all end up being about 50 % of what they are at 6 V as these specifications scale roughly 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 fitting, you could try swapping tires or using a small dab of glue to greatly 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 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 usually 2.5 mm long. The motor steps 6 mm in diameter and 9.3 mm long, and the gearbox length, labeled “L” in the diagram below, depends on 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 part, which includes 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 engine 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 train bears different load. Planetary gearboxes, on the other hand, share equivalent load over multiple gears, making them more durable for high torque program.
