If you require a smaller sized design for a credit card applicatoin requiring lower load capability, we also manufacture value-added Spur Gear Motors. Learn more about the various features and benefits inside our Planetary Gear Motor vs. Spur Gear Motor design note.
Built to your specific requirements
Most of our DC Motors could be complimented with one of our Planetary Gearheads. Ever-Power will work with you to design and manufacture a Planetary Gear Electric motor which will optimize the overall performance of your application.

Ever-Power is a DC planetary gear motor producer providing custom-designed solutions for all applications. Ask for a quote for planetary gear motors or contact us for assistance with your design.
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 contain a coreless electric motor fastened to a planetary gearbox by a little clip. The gears are made 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 just one 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 speed of 90 RPM and stall torque of 12 oz-in (900 g-cm) in 6 V
Note: Stalling or overloading gearmotors can greatly decrease their lifetimes and actually result in immediate damage. For these gearboxes, the recommended higher limit for instantaneous torque can be 3.5 oz-in (250 g-cm); we strongly advise keeping applied 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; an over-all recommendation for brushed DC motor operation is 25% or 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 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 acceleration, 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.
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 match loosely occasionally. In the event that you experience a loose fit, you could try swapping wheels or using a small dab of glue to help hold the wheel on.
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” portion of the shaft is usually 2.5 mm long. The motor measures 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 before the gearbox for a much better resolution. Its 4 mm output shaft makes it compatible with lots of ep mounts and part, which includes clamping hubs, Planetary motor mounts, and also 4 mm toothed wheels and pinion gears.

Spur Gear vs. Planetary Gear
The two most 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 capability of spur type gearbox is bound 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 app.
