How to choose the specifications of servo motors?

When selecting servo motor specifications, the first step is to evaluate the dynamic performance requirements of the application, such as acceleration, speed, and accuracy. Next, calculate the required maximum output torque based on the load characteristics and consider the safety factor. The size of the motor should be selected based on the installation space and mechanical structure limitations, while considering the cooling method. The selection of encoders should be based on control accuracy requirements, while the matching of drivers needs to ensure compatibility of voltage, current, and control interfaces. The selection of cables and connectors should ensure stable signal transmission and consider cost-effectiveness. The selection tools provided by manufacturers, such as Siemens DA65, PM21, etc., can assist in precise selection.
