38 MACHINERY UPDATE JANUARY/FEBRUARY 2015 www.machineryupdate.co.uk Components Drive systems tough it out in hostile shellfish environment “This new Nord solution means we no longer worry about drives all the time,” says Bram de Visser, technical service at the Dutch premium shellfish supplier Aspecial surface treatment introduced by Nord Drivesystems has allowed aluminium geared motors at shellfish product supplier Krijn Verwijs to survive the hostile working environment. Before swapping to the new system, frequent drive replacements used to be the order of the day but, in contrast to standard cast Treated motor on left, untreated above iron geared motors, the nsd tupH surface treated motors from Nord suffer almost no corrosion in the plant. Krijn Verwijs is one of Europe’s foremost suppliers of shellfish products, blue mussels in particular. Fresh catches arriving at the factory are dumped into large basins with a constant flow of clean salt water, which serves to keep the product healthy while sand is thoroughly rinsed off. Given the close presence of these containers and the fact that live mussels are then conveyed wet as they come, all processing lines throughout the factory are inevitably exposed to a humid, salty atmosphere. This aggressive environment brings swift corrosion for all sorts of unprotected metal parts across process automation equipment. In the case of conventional cast iron geared motors, rusty spots first appear on brand new systems in a matter of weeks, and the end of life draws near for these units after only a year or two. Even special coatings or varnishes merely help to moderately delay the onset of corrosion. Stainless steel drives are not an option since they proved not only very costly but impractical – due to requisite disruptive cool off periods before every hose down. However, Nord says its nsd tupH surface treatment is resilient, affordable and easy to clean and it enables aluminium geared motors – which can very comfortably be washed down – to achieve stainless steel grade resistance to corrosion. LONGER SURFACE LIVES Krijn Verwijs has begun to roll out nsd tupH systems to provide considerably longer service lives in the salty atmosphere throughout its site. Though such aluminium geared motors do come at a premium compared to the price of conventional cast iron units, both lab trials and extensive real-life testing in the factory in Yerseke, Holland indicate that nsd tupH systems will last for the better part of the typical 10-year lifetime of a conveyor line, or even outlast the line. Krijn Verwijs will therefore no longer have to purchase five to ten replacement drives for every unit, nor bother with the expense and effort of maintenance work. The nsd tupH treatment is no coating application, but rather a surface conversion that produces a base layer permanently bonded to the substrate. Based on an electrolytic process, this treatment renders aluminium cases similarly unsusceptible to corrosion as stainless steel. The scratch resistant surface also becomes more than six times as hard as untreated alloy, and a thousand times as hard as paint. Featuring a lightweight, compact, and self-draining design, nsd tupH systems for the food industry can be easily washed down. They are impervious to common chemical cleaning agents while neither rinsing them with acids or alkaline solutions nor applying highpressure cleaners will do any damage. In addition, nsd tupH surface treatments are universally available for all Nord aluminium products. T 01235 534404 W www.nord.com

A synchronous reluctance motor that combines all of the energy saving benefits of permanent magnet technology together with the service friendliness of an induction motor platform paired with an ABB industrial drive and advanced software, combine to offer a complete package for end users and OEMs. ABB’s motor has no rotor windings in the traditional sense. The rotor therefore, suffers virtually no power losses and its temperature remains lower than in conventional rotors, delivering losses typically 40% lower than its induction motor counterpart. The motor is available in two distinct packages, the first is a motor which is the same physical size as a standard IE induction SynRM motor and variable speed drives that make up the SynRM package motor but operates at IE4 efficiency levels. The second variant is called ‘High Output’, which is typically two frame sizes smaller for the same equivalent power compared to induction motors and still maintains IE3 energy efficiency levels. A variable-speed drive is required to control ABB’s SynRM motor. These VSDs have a range of features designed to deliver accurate and reliable process control, such as direct torque control designed for highly accurate motor torque and speed, safe torque-off to allow for reliable isolation for maintenance, built-in safety features and programming tools. A SynRM and VSD package can be specified by an ABB engineer or an authorised value provider, to ensure the right package is installed and commissioned according to exact end use requirements and duty cycles.

Available in four sizes, the IMA line of integrated motor rod actuators features stroke lengths from 76.2mm to 457.2 mm and peak thrusts from 890 to 30,594N at speeds up to 610 mm a second. “Many applications within the food and beverage industry require high-force electric actuators that can withstand the rigours of sanitary wash down,” says Steve McKay, md of Motion Control Products. “New IMA actuators with a food grade white epoxy coating and ingress protection rating of IP67 are an economical alternative to custom stainless steel actuators. The IMA actuator series is compact and durable.
