If you require a smaller sized design for a credit card applicatoin requiring lower load capacity, we also manufacture value-added Spur Gear Motors. Find out more about the various features and benefits inside our Planetary Gear Motor vs. Spur Gear Motor style note.
Built to your specific requirements
The majority of our DC Motors could be complimented with one of our Planetary Gearheads. Ever-Power will continue to work with you to create and produce a Planetary Gear Motor which will optimize the functionality 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 advice about your design.
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 electric motor fastened to a planetary gearbox by a small clip. The gears are manufactured from liquid crystal polymers (LCPs), and gearbox’s nylon result shaft is compatible with our 14 mm tires. Three gear ratios can be found:
26:1, which has 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) at 6 V
Take note: Stalling or overloading gearmotors may greatly reduce their lifetimes and actually result in immediate harm. For these gearboxes, the suggested upper limit for instantaneous torque is 3.5 oz-in (250 g-cm); we strongly advise keeping applied loads well under this limit. Stalls can also lead to rapid (possibly on the order of seconds) thermal harm to the motor windings and brushes; a general recommendation for brushed DC electric 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 generally, these types of motors can be used at voltages outdoors this range (rotation typically starts among 0.2 V and 0.3 V). Lower voltages might not be useful, and higher voltages could begin negatively affecting the life span of the motor. When operating at 3 V, the free-run quickness, stall torque, and stall current will all end up being approximately half of what they are in 6 V as these specifications scale roughly 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 might cause press-suit attachments like our 14 mm wheel to fit loosely occasionally. If you experience a loose fit, you could attempt swapping tires or using a small dab of glue to greatly help hold 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’s flattened by 0.5 mm. The “D” part of the shaft is usually 2.5 mm long. The engine actions 6 mm in diameter and 9.3 mm long, and the gearbox size, labeled “L” in the diagram below, depends on the gear ratio.
26 RPM Planetary Gear 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 helps it be compatible with lots of ep mounts and part, which includes clamping hubs, Planetary motor mounts, as well as 4 mm toothed wheels and pinion gears.

Spur Gear vs. Planetary Gear
The two the majority of 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 limited because each equipment in the teach bears different load. Planetary gearboxes, on the other hand, share the same load over multiple gears, making them stronger for high torque software.
