June 17, 2016 - Recently announced by Kollmorgen, the ERD series stainless steel linear actuators combine the AKMH series servo motors with ballscrew driven transmissions as IP69K-rated packages that are ready-to-install in food, produce or pharmaceutical machinery and other high-hygiene applications.
Designed for use with Kollmorgen AKD or AKD-N series centralised and decentralised servo drives, the ERD actuators use single-cable technology – a single cable for power and feedback. A choice of encoder feedback includes digital resolver SFD3 and Hiperface DSL. The 316 stainless steel housed AKMH series servo motor has a torque derating of under 20%.
Aimed at precision positioning tasks such as lifting units, closing or feed axes, or for machine format adjustments, the actuators are available with inline or reverse (parallel) motor mount configurations. A choice of four AKMH servo motors (72,5 to 132 mm diameter), allows the ERD a thrust force of up to 20 kN with feed speeds to over 1 m/sec over a stroke length of up to 600 mm. For compact installation the actuator screw section diameter ranges from 42 to 132 mm across the four frame-sizes.
For installation flexibility, a choice of mounting versions include foot, flange, trunnion and clevis pin, with the actuator rod supplied with internal or external threads and an optional support bracket. A pressure compensation feature prevents condensation from forming inside the motor.
Heason Technology provides full support for Kollmorgen’s ERD series actuators and its full line of motion components and systems with a GOLD Partnership agreement within the global manufacturer’s Premier Partner programme.
