Ever-Power is a DC planetary gear motor producer providing custom-designed solutions for all applications. Request a quote for planetary gear motors or contact us for advice about your design.
These tiny brushed DC gearmotors possess a diameter of just 6 mm and weigh just 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 small clip. The gears are manufactured from liquid crystal polymers (LCPs), and gearbox’s nylon result shaft is compatible with this 14 mm tires. Three gear ratios are available:
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, 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 swiftness of 90 RPM and stall torque of 12 oz-in (900 g-cm) in 6 V
Note: Stalling or overloading gearmotors may greatly decrease their lifetimes and also result in immediate harm. For these gearboxes, the suggested higher 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 result in rapid (potentially on the purchase of seconds) thermal harm to the electric 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 generally, these types of motors can be utilized at voltages outdoors this range (rotation typically starts among 0.2 V and 0.3 V). Lower voltages is probably not useful, and higher voltages could begin negatively influencing the life span of the motor. When operating at 3 V, the free-run velocity, stall torque, and stall current will all end up being about 50 % of what they are at 6 V as these specifications scale approximately linearly with voltage.
Since the gearmotor’s output shaft is nylon, there may be small variances in the diameter from unit to unit. These variations might cause press-match attachments like our 14 mm wheel to match loosely in some instances. If you experience a loose fitting, you could attempt swapping tires or using a small dab of glue to greatly help contain 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’s flattened by 0.5 mm. The “D” part of the shaft is certainly 2.5 mm long. The electric motor measures 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 includes a magnetic encoder mounted prior to the gearbox for a better resolution. Its 4 mm output shaft makes it compatible with lots of ep mounts and component, which includes clamping hubs, Planetary electric motor mounts, along with 4 mm toothed tires and pinion gears.

Spur Equipment vs. Planetary Gear
The two most common setup of DC motor gearbox are spur and planetary. Spur type gearbox are simpler, less costly, and work greatest for low torque applications. Torque capacity of spur type gearbox is bound 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 program.
