NORD DRIVESYSTEMS has expanded its range of high-efficiency smooth-surface motors.

Illustration: NORD IE4 smooth-surface motors meet the highest standards of efficiency, reliability, and durability under adverse conditions

The new permanent-magnet synchronous motors without cooling fins achieve level IE4 / super premium efficiency. This can greatly benefit the food, beverage, and pharmaceutical industries, and other hygienically demanding applications. The efficient smooth-surface motors are suitable for use in dry areas as well as in applications requiring frequent cleaning. As they generate very little excess heat, they need no fans and therefore do not contribute to the spreading of germs. The IE4 or Super Premium Efficiency synchronous motors operate significantly more efficiently than induction motors, specifically in the partial load range. This results in substantially lower cost for energy consumption and lower TCO. The motors furthermore feature a particularly high power density and a very long product life. Frequency inverters can be mounted directly onto the motor or near the motor for perfect flexibility.

Three motor sizes (80, 90, 100) with power ratings from 0.75 to 2.2 kW are available. They complement the existing smooth-surface induction motor range, which already covers outputs from 0.37 to 1.1 kW. The motors can be supplied with a brake. For washdown-enabled inverter-controlled drive systems with an IP66/IP69K protection rating, NORD can draw on four different suitable gearbox series. Washdown drive configurations all feature die-cast aluminum housings with smooth surfaces, designed so that cleaning fluids and foams easily run off. For extra corrosion protection, they can be fitted with the nsd tupH Sealed Surface Conversion System, which is approved for food and drink applications in accordance with FDA Title 21 CFR 175.300.
