How to Select Between Iron-Core and Ironless Linear Motors? DGSMARTWIN Provides the Definitive Answer

As a core component of direct drive motion systems, linear motors are widely uses in key scenarios such as automated production lines and precision automation equipment. The rationality of their selection directly determines the operational efficiency, positioning accuracy and maintenance cost of automated production lines. In the current automation industry selection process, equipment manufactures and production line upgraders are constantly troubled by the dilemma of choosing between iron-core and ironless linear motors. The two follow different technical routes, have different performance focuses, and are suitable for significantly different automation scenarios. As a leading enterprise in China’s direct drive industry, DGSMARTWIN has deeply rooted itself in the automation industry for more than ten years, and has built a complete linear motor product matrix covering both iron-core and ironless types. Relying on its full-chain independent R&D capabilities and scenario-based adaptation advantages, it provides precise solutions for industry selection. Combined with the practical application needs of the automation industry and related products, this article deeply analyzes the core difference between the two type of linear motors to provide a reference for industry selection.

The core differences between iron-core and ironless linear motors stem from the structural design of the stator and mover, which also determine their respective application orientations in automation scenarios. Iron-core linear motors adopt a structure with coils wound around laminated iron cores. Relying on the magnetic focusing effect of the iron core, they achieve high thrust density, high rigidity and excellent heat dissipation, making them the ideal choice for heavy-duty and high-speed automation scenarios.

The CFS Series iron-core linear motors launched by DGSMARTWIN further solve the pain points of traditional iron-core motors through magnetic circuit optimization and cogging force compensation technology. Featuring a lightweight, compact mover and wide thrust range, they are perfectly suitable for new energy, 3C automation, semiconductor and other applications. Traditional iron-core motors suffer from obvious cogging effect, which easily causes motion jitter and speed ripple, making them unsuitable for high-precision automation inspection, micro automation assembly and other scenarios, while requiring high rigidity of the mounting base. Through technical optimization, SMARTWIN CFS Series greatly reduces cogging force, further expanding its adaptability to medium and high-precision automation scenarios.

Ironless linear motors adopt an ironless winding design, with the mover consisting only of a hollow coil. This fundamentally eliminates cogging effect and magnetic attraction force, achieving zero cogging, ultra-smooth motion and lightweight advantages, making them perfectly suitable for high-precision, high-speed and light-load scenarios in the automation industry. Leveraging its full-chain independent R&D capability covering “linear motors – servo drives – high-precision encoders”, the ironless linear motor series of DGSMARTWIN is easy to install and can be flexibly integrated into small automation equipment. They are widely used in medium-to-high-end applications such as precision automation assembly for 3C electronics, semiconductor automated inspection, and medical automation equipment. By optimizing production processes and supply chain layout, DGSMARTWIN effectively controls costs while ensuring product performance, improving the cost-performance ratio of ironless linear motors in the automation industry.

For the automation industry, the core of product selection is "scenario adapted and cost controlled". For the construction of heavy-duty, high -speed and cost-effective automated production lines, such as general automated production lines and heavy-duty automated handling equipment, iron-core linear motors are the optimal choice. With its technical advantages and high adaptability, SMARTWIN CFS Series has become the top pick for many automation enterprises. For high-precision, high-speed and light-load automation scenarios such as precision automated inspection and micro automated assembly, ironless linear motors enjoy greater advantages. SMARTWIN ironless series can provide customized solutions to precisely match scenario requirement. With the continuous upgrading of the automation industry, the two types of linear motors are not in a substitute relationship but complementary and coexistent. Relying on a complete product matrix, DGSMARTWIN achieves full-scenario coverage from light load to heavy load and from ordinary precision to ultra-high precision. It also provides a full-process service system covering selection consultation, customized development and after-sales maintenance, helping automation enterprises reduce costs, improve efficiency, and realize independent control of core components, providing core power support for the upgrading of automated production lines and the iteration of intelligent equipment.
