Ever-Power is a DC planetary gear motor producer providing custom-designed solutions for all applications. Ask for a quote for planetary equipment motors or contact us for advice about your design.
These tiny brushed DC gearmotors have 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 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 this 14 mm wheels. Three gear ratios can be found:
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 velocity of 90 RPM and stall torque of 12 oz-in (900 g-cm) in 6 V
Take note: Stalling or overloading gearmotors may greatly reduce their lifetimes and even result in immediate damage. For these gearboxes, the suggested top limit for instantaneous torque is definitely 3.5 oz-in (250 g-cm); we highly advise keeping applied loads well under this limit. Stalls may also result in rapid (potentially on the purchase of seconds) thermal harm to the engine windings and brushes; a general recommendation for brushed DC electric 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 in general, these types 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 begin negatively influencing the life of the electric motor. When operating at 3 V, the free-run quickness, stall torque, and stall current will all become about 50 % of what they are at 6 V as these specifications scale roughly linearly with voltage.
Because the gearmotor’s output shaft is nylon, there can be small variances in the diameter from unit to unit. These variations might cause press-suit attachments like our 14 mm wheel to fit loosely occasionally. If you experience a loose fitting, you could attempt swapping tires or using a little dab of glue to help contain the wheel on.
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 is flattened by 0.5 mm. The “D” portion of the shaft is 2.5 mm long. The motor actions 6 mm in diameter and 9.3 mm long, 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 includes 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 component, including clamping hubs, Planetary engine mounts, and also 4 mm toothed tires and pinion gears.

Spur Equipment vs. Planetary Gear
The two many 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 equivalent load over multiple gears, making them stronger for high torque application.
