Overview
These tiny brushed DC gearmotors have a diameter of just 6 mm and weigh simply over a gram, making them great actuators for miniature robots and incredibly small mechanisms. They consist of a coreless electric 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 our 14 mm wheels. Three gear ratios can be found:
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, 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 swiftness of 90 RPM and stall torque of 12 oz-in (900 g-cm) at 6 V
Notice: Stalling or overloading gearmotors may greatly decrease their lifetimes and even result in immediate harm. For these gearboxes, the recommended top limit for instantaneous torque can be 3.5 oz-in (250 g-cm); we highly advise keeping used loads well under this limit. Stalls can also result in rapid (potentially on the purchase of seconds) thermal damage to the motor windings and brushes; an over-all recommendation for brushed DC engine procedure is 25% or 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 outdoors this range (rotation typically starts between 0.2 V and 0.3 V). Lower voltages is probably not useful, and higher voltages could start negatively influencing the life span of the motor. When operating at 3 V, the free-run rate, stall torque, and stall current will all end up being 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 can be small variances in the diameter from unit to unit. These variations may cause press-fit attachments like our 14 mm wheel to match loosely in some instances. In the event that you experience a loose fitting, you could try swapping tires or using a little 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 output shaft, which is 2 mm in diameter with a section that is flattened by 0.5 mm. The “D” part of the shaft is 2.5 mm long. The engine procedures 6 mm in diameter and 9.3 mm in length, and the gearbox duration, labeled “L” in the diagram below, depends on 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 better resolution. Its 4 mm output shaft helps it be compatible with lots of ep mounts and part, including clamping hubs, Planetary motor mounts, in addition to 4 mm toothed tires and pinion gears.

Spur Equipment vs. Planetary Gear
The two many common setup of DC motor gearbox are spur and planetary. Spur type gearbox are simpler, less costly, and work best 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 equivalent load over multiple gears, making them more durable for high torque application.
