JUSTEK has developed a range of customisable direct-drive motors using Renishaw’s high- performance optical position encoders, including the miniature ATOM optical encoder, for OEM customers that sell manufacturing equipment into the FPD, semiconductor and electronics industries
The right encoder for the job J
USTEK is a motion control component manufacturer based in Gyeonggi-do, Korea. It designs and builds linear motors,
direct-drive rotary (DDR) motors, motion stages and conveyors. The flat panel display (FPD) manufacturing
industry in South Korea, which includes electronics giants such as Samsung and LG, meets over a third of the global TV market demand. The market for advanced FPD organic light
emitting diode (OLED) and quantum-dot light emitting diode (QLED) technologies has grown significantly — particularly in the small- sized display market representing smart phones and tablet computers. Motion control systems are an essential part
of FPD manufacturing equipment and are responsible for ensuring that the required manufacturing precision is maintained. JUSTEK has developed a range of
customisable direct-drive (DD) motors using Renishaw’s high-performance optical position encoders, including the miniature ATOM
optical encoder, for OEM customers that sell manufacturing equipment into the FPD and semiconductor/electronics industries.
THE CHAllEngE 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. To this end, motion control vendors have added and are continuously improving the onboard intelligence of components — giving them the computational capability and communications necessary to participate in connected strategies. 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. JUSTEK's DD motors are compact and are
designed for precision process equipment in the FPD and semiconductor industries. Integrated encoders for position feedback must comply with a wide range of end-user requirements relating to size, weight, performance and reliability.
THE SOlUTiOn JUSTEK has chosen Renishaw's family of ATOM miniature encoder solutions for its DD motors and motion stages. Young-dong Jo, JUSTEK’s product manager,
explains the advantages of the ATOM encoder : “The miniature design of the ATOM readhead is ideal for our DD motors as space inside the motors is inherently limited. There are relatively few encoders options available on the market that meet our requirements for volume and performance. Initially, we tried some other encoder brands but found them
