Application and selection of collaborative innovative combination of servo motor and planetary gearbox

In the modern industrial field, the collaborative innovation combination of servo motors and planetary reducers has demonstrated strong performance and broad application prospects. Next, we will elaborate on its application in different scenarios with examples and introduce the key points of selection.

1、 Application scenarios

1. Industrial automation

Industrial automation requires high-precision, high-speed, and high torque motion control. For example, in the electronic manufacturing industry's surface mount robots, servo motors provide precise position and speed control, while planetary gearboxes increase torque, allowing the robot to quickly and accurately pick up and place tiny electronic components. The surface mount robot of a certain electronic factory adopts this combination, which significantly improves production efficiency and surface mount accuracy, and reduces the defect rate.

2. CNC machine tools

Numerical control machine tools require precise axis motion and strong cutting force during the machining process. The servo motor ensures precise positioning of the coordinate axis, while the planetary gearbox converts the high-speed rotation of the motor into low-speed, high torque output suitable for cutting. On a CNC milling machine in a mold processing factory, this combination enables the machine tool to maintain stable cutting performance when processing complex molds, improving the machining accuracy and surface quality of the molds.

3. Automated logistics and warehousing

In automated three-dimensional warehouses, the operation of stacker cranes requires rapid positioning and load-bearing of heavy objects. The servo motor and planetary reducer work together to achieve fast shuttle and accurate loading and unloading of goods between the shelves of the stacker crane. The logistics center of a large e-commerce company has used this combination of stacker cranes, greatly improving the efficiency and accuracy of warehousing and logistics.

2、 Key selection points

1. Torque and speed requirements

Select the appropriate model based on the load characteristics and motion speed requirements of the application scenario. For example, in a heavy-duty handling robot, it is necessary to calculate factors such as the weight, friction, and acceleration of the transported object to determine the required torque and speed, in order to select a servo motor that can provide sufficient power and a matching planetary gearbox.

2. Accuracy and return gap

For high-precision applications such as CNC machine tools and precision measuring equipment, it is necessary to choose planetary reducers with high precision and small return clearance to ensure the accuracy of motion. A certain precision machining workshop paid special attention to the accuracy indicators of planetary reducers when selecting its CNC lathe, in order to meet the requirements of machining high-precision parts.

3. Installation space and size limitations

Consider the structure and installation space of the equipment, and select servo motors and planetary reducers of appropriate sizes. In a compact automated production line, it is necessary to choose a combination of small size but powerful performance to adapt to limited installation space.
