Overview
These tiny brushed DC gearmotors have got a diameter of simply 6 mm and weigh just over a gram, which makes them great actuators for miniature robots and incredibly small mechanisms. They contain 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 output shaft is compatible with this 14 mm tires. Three gear ratios are available:
26:1, which has 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
Take note: Stalling or overloading gearmotors can greatly decrease their lifetimes and actually result in immediate damage. For these gearboxes, the recommended upper 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 (potentially on the purchase of seconds) thermal harm to the engine 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 in general, these kinds of motors can be utilized at voltages outdoors 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 affecting the life span of the electric motor. When operating at 3 V, the free-run acceleration, 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 in some instances. If you experience a loose fitting, you could try swapping wheels or using a small 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 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 definitely 2.5 mm long. The motor procedures 6 mm in diameter and 9.3 mm long, and the gearbox duration, 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 before the gearbox for a much better resolution. Its 4 mm output shaft makes it compatible with plenty of ep mounts and part, which includes clamping hubs, Planetary electric motor mounts, in addition to 4 mm toothed tires and pinion gears.

Spur Equipment vs. Planetary Gear
The two many 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 equipment in the train bears different load. Planetary gearboxes, on the other hand, share the same load over multiple gears, making them stronger for high torque application.
