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 automotive manufacturing, machining, steel structures, and more. To improve the performance and efficiency of welding equipment, many manufacturers have begun using integrated servo motors as the main drive components for welding equipment. This article introduces the application background and advantages of integrated servo motors in welding equipment, as well as equipment introduction, application functions, and case analysis.

01. Introduction

Traditional welding equipment drive methods suffer from issues such as large size, heavy weight, and insufficient control precision. These problems lead to unstable motion speed in traditional welding equipment, affecting welding quality and efficiency.

To solve these problems, many manufacturers have started using integrated servo motors as the main drive components for welding equipment.

An integrated servo motor is a product that integrates a servo driver, encoder, DI/DO, and servo motor into a single unit, featuring high integration, high precision, fast response, high stability, and reliability. In welding equipment, integrated servo motors are typically used in conjunction with transmission components such as reducers and ball screws, serving as the actuators of the welding equipment.

02. Application Solution

In practical applications, a welding equipment manufacturer adopted an integrated servo motor drive system to achieve high-precision and high-efficiency welding process control.

The integrated servo motor controls up-and-down movement by receiving pulse signals from the PLC, with an operating frequency of up to 1000 rpm. After practical application evaluation, the equipment not only simplified the transmission structure but also improved equipment precision and efficiency, reducing production costs for the enterprise and enhancing market competitiveness.
