Overview
These tiny brushed DC gearmotors have got a diameter of just 6 mm and weigh just over a gram, making them great actuators for miniature robots and very small mechanisms. They contain 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 result shaft is compatible with this 14 mm tires. 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, which has a free run speed of 90 RPM and stall torque of 12 oz-in (900 g-cm) at 6 V
Note: Stalling or overloading gearmotors may greatly reduce their lifetimes and even result in immediate damage. For these gearboxes, the recommended higher limit for instantaneous torque can be 3.5 oz-in (250 g-cm); we strongly advise keeping applied loads well under this limit. Stalls may also lead to rapid (potentially on the purchase of seconds) thermal damage to the electric motor windings and brushes; an over-all recommendation for brushed DC electric motor 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 utilized at voltages outside this range (rotation typically starts among 0.2 V and 0.3 V). Lower voltages may not be practical, and higher voltages could begin negatively impacting the life span of the motor. When operating at 3 V, the free-run swiftness, stall torque, and stall current will all become approximately half 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 may cause press-fit attachments like our 14 mm wheel to fit loosely occasionally. If you experience a loose fitting, you could attempt swapping wheels or using a small dab of glue to greatly help hold the wheel on.
Gearmotor dimensions
The following diagram shows the micro plastic gearmotor dimensions in mm. The planetary gearbox has a D-shaped plastic result shaft, which is 2 mm in diameter with a section that’s flattened by 0.5 mm. The “D” portion of the shaft is certainly 2.5 mm long. The electric motor actions 6 mm in diameter and 9.3 mm in length, 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 before the gearbox for a better resolution. Its 4 mm output shaft helps it be compatible with plenty of ep mounts and component, including clamping hubs, Planetary engine mounts, along with 4 mm toothed wheels and 
pinion gears.

Spur Gear vs. Planetary Gear
The two most common setup of DC electric motor 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 limited because each equipment in the train bears different load. Planetary gearboxes, in contrast, share equal load over multiple gears, making them more durable for high torque program.
