To help machine designers in the semiconductor and electronics industries easily increase the power of linear motors, the LMG and LMS line of ironcore motors is pin-to-pin compatible so that upgrading from one to the other requires minimal effort.
The key difference between the two motors is the LMS’ extra height, which allows for approximately 30% more continuous force if the application requires it.
Until now, the LMG’s smaller sizes were not available as an LMS equivalent. Both models share the same footprint, peak force, mounting interface, cable outputs and magnetic track making an exchange between the two as simple as replacing the carriage if necessary. Each motor uses ETEL’s patented design, which minimizes the amount of force ripple typical of ironcore motors while maintaining the high-force density that other anti-cogging designs sacrifice.
These linear motors only require one magnetic track and are compliant to 600 V. They can reach speeds up to 10 m/sec, an acceleration of 20 g, and reach a peak force up to 3,650 N. Both models come in a variety of sizes that differ in length and width to meet the application requirement.
The LMG/LMS linear motor series are for direct drive applications. Advantages over transmission-based devices include:
- fewer parts requiring lower overall costs
- stable performance all along machine lifetime due to zero maintenance required on the motors
- no backlash, allowing for better accuracy and repeatability
- smooth, precise, and efficient motions
- compact design
