NORD Drivesystems has introduced a new range of efficient drive units for dynamic speed control and automatic process control in applications that need regular high-pressure steam jet cleaning.
Developed for strict hygiene requirements and featuring IP66/IP69K ingress protection, the smooth-surface motors with an integrated frequency inverter are available for the 0.37 - 1.1 kW performance range. Common applications for these drive units include conveyors, pumps, mixers, and agitators.
Sensor data such as pressure or flow rate values can be directly communicated to the drives, enabling them to automatically adapt to current demand. If partial load operation is frequent, an automatic energy-saving function decreases the running costs by a significant share. In conveyor applications, light barriers can be used for contact-free or gapless accumulation. A soft start function reduces the starting current and results in less stress on the mechanical system and the transported goods.
Key features of the SK 180E variable speed drives include tolerance for high temperature fluctuations; suitable for ambient temperatures from -25°C to +50°C; rugged die-cast aluminium housing absorbing impacts up to 7J; cooling fins especially flat and easy to clean; and operable on standard domestic power sockets.
NORD also manufactures a range of gearboxes with especially smooth surfaces and high power density. Full compatibility of all components enables fine-tuning of output speed and torque according to actual plant requirements. The optional nsd tupH surface conversion treatment equips the aluminium smooth-surface motors and gearboxes with corrosion resistance similar to stainless steel drives without the scratch or chipping risks of a paint finish.
The drives are much lighter and have a better thermal performance than stainless steel units. The NORD-developed treatment is compliant with FDA Title 21 CFR 175.300 requirements. Commissioning and operation of these integrated drives is very user-friendly, including in applications with a large number of drives and spacious facilities.
