Sailent develops and produces planetary gearboxes, micro gear motors, planetary reducers, and other gear transmission products, which have undergone various tests such as high and low temperature, lifespan, and salt spray.
Next, let me introduce the structural features and working characteristics of the planetary reducer.
Structural features of the planetary reducer:
The main structures of the planetary reducer include the sun gear, planet gears, internal gear ring, and planet carrier.
To ensure that the load of the three planet gears is evenly distributed, a gear floating mechanism is used, where either the sun gear or the planet carrier floats, or both the sun gear and the planet carrier float simultaneously. The gears in the reducer are straight-toothed involute cylindrical gears. They have the following characteristics:
1. Small size, under the same usage conditions, the volume is 1/2 to 1/3 smaller than that of ordinary reducers.
2. Transmission efficiency: single-stage planetary reducers achieve over 90%; two-stage planetary reducers achieve over 80%; three-stage planetary reducers achieve over 70%.
3. Wide transmission range: i=2.8 to 2000.
4. Strong adaptability and durability. The main components are made of high-quality alloy steel treated with carburizing quenching or nitriding, ensuring that the planetary reducer operates smoothly, with low noise and a longer service life.
Working characteristics of the planetary reducer:
(1) The gear is made of low-carbon alloy steel through carburizing quenching, with a tooth surface hardness of HRC54-62.
(2) Precision rolling process is used, ensuring high precision and good meshing.
(3) Load capacity is more than 10 times higher than that of spur gearboxes.
(4) Transmission efficiency can reach 90%, with a long service life.
Planetary gearboxes, micro gear motors, planetary reducers, and other applications are found in intelligent transmission, smart homes, automotive transmission, medical devices, and other fields. Sailent welcomes your inquiries.

Introduction to Micro DC Gear Motors
Introduction to Micro DC Gear Motors Micro DC gear motors are a miniaturized motor system, typically consisting of a DC motor and a gearbox. Here are some related introductions to micro DC gear motors: DC Motor Section: Working Principle: The DC motor generates current by moving a conductive coil in a magnetic field, thus producing electromagnetic force to drive the motor's rotation. Structure: Micro DC motors usually adopt a separate structure, including an armature (rotating part) and an electromagnet (stator part). Types: Common types of DC motors include brushed DC motors and brushless DC motors. Brushed DC motors use brushes to connect to the armature, while brushless DC motors control current through an electronic speed controller, eliminating the need for brushes. Gearbox Section: Function: The gearbox is used to slow down the motor's output speed while increasing torque. This is crucial for applications requiring higher torque and lower speeds, such as robotic arms and camera gimbals. Structure: Gearboxes typically consist of gears that achieve the reduction ratio through different gear combinations. The reduction ratio is the ratio of input speed to output speed. Types: Common types of gearboxes include planetary gears, worm gears, and helical gears. Different types of gearboxes are suitable for different application scenarios. Applications: Micro DC gear motors are widely used in various fields, including consumer electronics (such as cameras and printers), medical devices, robotics, and automotive electronics. In these applications, micro DC gear motors are typically used to control precise movements, provide sufficient torque, and achieve efficient performance in limited spaces. Control and Drive: Micro DC gear motors usually require corresponding electronic speed controllers or controllers to precisely control rotation speed and direction. The control system can adjust the motor's output according to application needs, achieving precise position control and speed regulation. Performance Parameters: The performance parameters of micro DC gear motors include rated voltage, rated speed, rated torque, efficiency, etc. These parameters are crucial for selecting and designing motor systems. In summary, micro DC gear motors have been widely applied under the trends of miniaturization, precision, and efficiency, providing reliable driving force for many electric devices and systems.
