Overview
These tiny brushed DC gearmotors have got a diameter of simply 6 mm and weigh simply over a gram, which makes them great actuators for miniature robots and very small mechanisms. They consist of 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 output 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 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 rate of 90 RPM and stall torque of 12 oz-in (900 g-cm) in 6 V
Note: Stalling or overloading gearmotors can greatly reduce their lifetimes and even result in immediate harm. For these gearboxes, the recommended top limit for instantaneous torque is 3.5 oz-in (250 g-cm); we highly advise keeping used loads well under this limit. Stalls may also result in rapid (possibly on the order of seconds) thermal harm to the motor windings and brushes; a general recommendation for brushed DC 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 generally, these kinds of motors can be used at voltages outside this range (rotation typically starts among 0.2 V and 0.3 V). Lower voltages is probably not practical, and higher voltages could start negatively impacting the life of the engine. When operating at 3 V, the free-run acceleration, stall torque, and stall current will all become about 50 % of what they are in 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 may cause press-suit attachments like our 14 mm wheel to match loosely in some instances. If you experience a loose fitting, 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 has a D-shaped plastic output shaft, which is 2 mm in diameter with a section that’s flattened by 0.5 mm. The “D” part of the shaft is 2.5 mm long. The electric motor procedures 6 mm in diameter and 9.3 mm in length, 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 includes a magnetic encoder mounted prior to the gearbox for a better resolution. Its 4 mm output shaft makes it compatible with plenty of ep mounts and part, which includes clamping hubs, Planetary motor mounts, along with 4 mm toothed tires and pinion gears.

Spur Equipment vs. Planetary planetary gear motor55514253220Gear
The two many common setup of DC motor 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 equal load over multiple gears, making them more durable for high torque program.
