Application of integrated servo motor in welding equipment
With the continuous development of the manufacturing industry, welding equipment has been widely used in many fields, such as automobile manufacturing, mechanical processing, steel structure and other fields. In order to improve the performance and efficiency of welding equipment, many manufacturers have begun to use integrated servo motors as the main driving components of welding equipment.
This paper will introduce the application background and advantages of integrated servo motor in welding equipment, as well as the introduction of the equipment, application functions and case analysis.
01. Introduction
There are some problems in the traditional welding equipment driving mode, such as the "welding equipment" is large, heavy, and the control accuracy is not high. These problems cause the traditional welding equipment to move at an unstable speed, which affects the welding quality and efficiency.
In order to solve these problems, many manufacturers began to use integrated servo motors as the main drive components of welding equipment.
Integrated servo motor is a kind of servo drive, encoder, DI/DO and servo motor integrated together, with high integration, high precision, fast response, high stability and reliability characteristics. In welding equipment, the integrated servo motor is usually used together with the transmission components such as the reducer and ball screw to be used as the actuator of the welding equipment.
02. Application Scheme
In practical applications, a welding equipment manufacturer uses an integrated servo motor drive system to achieve high-precision and high-efficiency welding process control.
The integrated servo motor can be controlled up and down by sending pulses with PLC, and the operating frequency can reach 1000r/min. After the practical application effect evaluation, the equipment not only simplifies the structure of the transmission, but also improves the accuracy and efficiency of the equipment, reduces the production cost for enterprises, and improves the market competitiveness.

【 Advantages of Integrated servo motor 】
High integration improves device portability: The integrated servo motor integrates functional modules such as brushless motor, driver, encoder and controller, greatly reducing the volume and weight of the device. At the same time, simplify the system wiring and reduce potential points of failure.
Flexibility to meet diverse needs: The integrated servo motor supports CAN/CANopen/Modbus communication, which can be flexibly controlled and adjusted according to needs to adapt to different work needs.
High-precision positioning to improve measurement accuracy: The integrated servo motor has a high positioning accuracy, which can achieve high-precision positioning of mobile devices.
Multiple control modes: Support PP, VM, PV, PT, HM, IP, CSP, CSV, CST Standard mode; Supports NiMotion position mode, NiMotion speed mode, and NiMotion torque mode.
High-speed response improves equipment efficiency: The integrated servo motor has a fast response speed.
Perfect alarm function: integrated servo motor power-on self-test diagnosis, can detect hardware faults in time to avoid affecting system operation equipped with a variety of safety protection functions, through the LED Flashing alarm, visual display of the current state of the motor, while with overvoltage/undervoltage, overheating, overcurrent, gridlock alarm and other protection functions.
