Overview
These tiny brushed DC gearmotors possess a diameter of just 6 mm and weigh simply over a gram, which makes them great actuators for miniature robots and incredibly small mechanisms. They consist of a coreless engine 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 are available:
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, 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 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 reduce their lifetimes and also result in immediate harm. For these gearboxes, the recommended higher limit for instantaneous torque is usually 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 purchase of seconds) thermal damage to the electric motor windings and brushes; an over-all recommendation for brushed DC engine 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 outside this range (rotation typically starts between 0.2 V and 0.3 V). Lower voltages is probably not useful, and higher voltages could begin negatively affecting the life of the engine. When operating at 3 V, the free-run swiftness, stall torque, and stall current will all become 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 might cause press-fit attachments like our 14 mm wheel to match loosely in some instances. If you experience a loose fit, you could try swapping tires 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 result shaft, which is 2 mm in diameter with a section that is flattened by 0.5 mm. The “D” portion of the shaft is certainly 2.5 mm long. The engine actions 6 mm in diameter and 9.3 mm long, and the gearbox length, labeled “L” in the diagram below, depends upon the gear ratio.
26 RPM Planetary Equipment Motor with encoder: compatibility
This small 12V motor has a magnetic encoder mounted prior to the gearbox for a much better resolution. Its 4 mm output shaft makes it compatible with lots of ep mounts and component, including clamping hubs, Planetary electric motor 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 expensive, and work greatest for low torque applications. Torque capacity of spur type gearbox is limited because each equipment in the teach bears different load. Planetary gearboxes, in contrast, share the same load over multiple gears, making them more durable for high torque program.
