ATOM™ Encoders Help JUSTEK Deliver Custom Motion Control Solutions that Drive up Profits
One of the greatest commercial challenges that OEMs face is one they share with their component manufacturers: understanding what the market will buy and how to differentiate it. Connected manufacturing machines that share data via the Internet of Things (IoT) are a promising opportunity for strategic differentiation. The motion control industry is preparing to help customers integrate motion technology into their connected solutions.
Motion control systems are an essential part of flat panel display (FPD) manufacturing equipment and are responsible for ensuring that the required manufacturing precision is maintained. Whether in applications with connected systems or more traditional standalone applications, well-designed and customer-specific motion control solutions are needed to support the latest OEM innovations.
This case study focuses on JUSTEK Inc., a leading motion control component manufacturer based in Gyeonggi-do, Korea. It designs and builds linear motors, direct-drive rotary (DDR) motors, motion stages, and conveyors. JUSTEK’s DD motors are compact and designed for precision process equipment in the FPD and semiconductor industries.
JUSTEK chose Renishaw’s family of ATOM miniature encoder solutions for its DD motors and motion stages. ATOM is a non-contact optical encoder with an open format, the advantages of which include the effective elimination of backlash, shaft wind-up (torsion), and other mechanical hysteresis errors that are inherent in traditional enclosed encoders.
The miniature design of the ATOM readhead was ideal for JUSTEK’s DD motors since space inside the motors is inherently limited. Before choosing ATOM optical encoders, JUSTEK tested them repeatedly and found that the ATOM had advantages in terms of reliability, system volume, and performance.
