A planetary gear motor is combination a micro planetary gearbox and a DC motor. It is a type driving device used to reduce speed and increase torque. Planetary gear motors are typically cylindrical and are made of steel or brass, although they can also be made of plastic to meet varying power levels and size requirements.
As one of the leading planetary gear motor manufacturers, INEED Motors offers DC planetary gear motors with a diameter range from 6mm to 42mm, which means the smallest planetary gear motor diameter we can do is 6mm. The rated voltage ranges from 2V DC-24V DC, the output speed is from 5rpm to 2000 rpm. Of course, planetary gear motors’ torque is also an important parameter for you to consider whether it is suitable for your application. The torque range we can make is from 5.0 g.cm-50.0 kg. cm. In recent years, we have successfully developed solutions with even greater torque for our esteemed customers, one of our representative products is the 12V DC motor high torque low rpm, and our product line has continued to expand. However, the torque generally remains within this range.
The planetary gear motor is an epicyclic gear train that reduces the output speed by meshing the small planetary gearbox.
The main components of the planetary gear motor are sun gear, planet gear, ring gear, planet carrier, and driving motor. It is similar to the orbital motion of the planets in our solar system. In a gear train set, three or more “driving” gears rotate around the sun gear with the sun gear as the driving center. A gear motor designed with this structure is called DC planetary gear motor.
The planetary gear set automatically runs and rotates along the ring gear, and the planet carrier is connected to the output shaft, which outputs to achieve acceleration.
To attain a higher reduction ratio (or torque), multiple sets of gears can be combined with planetary gears so as to double the reduction ratio (or torque).
The planetary motor gearbox shares the load torque, thus reducing wear and pressure, which makes planetary gear motors able to easily provide a lot of power transmission without damaging the gears.

Gear ratio Formula:
A planetary gear motor reduces the speed of a micro DC motor or other high-speed rotating power by meshing a smaller gear with fewer teeth on the input shaft of the planetary gearbox and a larger gear with more teeth on the output shaft.
By connecting gears of different sizes, the output speed of the gear motor can be reduced while increasing its torque. When power is transmitted from the smaller gear to the larger gear, the ratio of the number of reductions to the number of torque amplifications is equal to the gear ratio of the two gears. This ratio is commonly known as the gear ratio. In other words, the tooth ratio between different gears is the gear ratio.
Torque is generated by the reduction ratio of the gearbox. The larger the reduction ratio, the greater the torque. Conversely, the smaller the reduction ratio, the smaller the torque.
The planetary motor is with high stability of angular rotation, providing higher precision and reliability.
Adding bearings for some gear motor types to avoid direct wear and swing of the output shaft.
Planetary gear systems are enclosed in cylindrical gearboxes, suitable for applications with compact space dimensions and lower weights.
Due to more surface contraction of gears, making rotation is softer.
Several planets evenly share the rated load instead of one gear. The more planet gears the gear motor has, the more rated load it shares.
The planetary reducer provides greater efficiency, and due to its design and internal layout, the efficiency loss can be minimized during the operation of the motor.

A planetary gear motor replicates the motion of a planetary system, with the input shaft causing the central gear (the sun gear) to rotate, and this in turn drives the planet gears surrounding it. The planetary gear motor is utilized in a diverse array of applications and is able to increase or decrease the speed through the planetary gears.
They contain three or more planetary gears per stage, which allows for more tooth contact between them, and the torque load is evenly distributed among the multiple planetary gears. The more planetary gears there are, the more load they share. Delivers large torque and smooth speed transfer in transmission (always with a good gear engagement.
No, a planetary gearbox does not increase power. Rather, it reduces speed and increases torque. Although there are occasionally gearboxes that can increase speed while decreasing torque, they are rare and most gearboxes are used to lower the speed of a motor while increasing its torque.
A gear train to increase torque or reduce speed. Gears increase torque by multiplying the input torque. For example, when two gears mesh together, one will turn clockwise and the other will turn in the opposite direction. The output torque is equal to the input torque times the ratio of the two gears.
The following two steps are used to calculate the output speed of the gearbox:
First, figure out the number of teeth on the input gear and output gear respectively, and then divide the number of teeth on the output gear by the number of teeth on the input gear to calculate the gear ratio.
Second, get the input speed. This is usually measured in revolutions per minute (RPM). Multiply the input speed by the gear ratio to calculate the output speed (RPM).
Planetary gear motors are used in a variety of applications, including robotics, home appliances, medical equipment, and industrial machinery. And other application where precision, high power density, and efficiency are needed.
