Automation for high-hygiene machinery

Designed for use with Kollmorgen AKD or AKD-N series centralised and decentralised servo drives, the ERD actuators benefit from the motion control innovator’s single-cable technology – a single cable for power and feedback which offers substantially less cabling and installation work. 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% which, when compared to typical competitive stainless motor thermal performance at around 30%, offers better servo performance.

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 and convenient installation the actuator screw section diameter ranges from 42 to 132 mm across the four frame-sizes.

The ERD’s all stainless steel construction and IP69K rated protection facilitates easy and rapid cleaning with no need for additional protective housings, which are cumbersome necessities on many high-hygiene automation machines. With faster cleaning possible, and use even where high pressure and high temperature cycles are called for, the smooth surfaces of the actuator avoid dirt and bacteria build-up. The fully sealed unit is lubricated with food grade grease and is certified for USDA, 3A, NSF requirements.

For installation flexibility a wide 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 new 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. Heason’s in-house design and build system integration service combines such components as part of bespoke integrated motion systems for high precision positioning and automation applications across industry and research.
