IE4 smooth-surface motors

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

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.

NORD DRIVESYSTEMS develops, produces and sells drive technologies with around 3.400 employees, and is one of the international leaders in the industry. In addition to standard drives, NORD supplies application-specific concepts and solutions, even for special applications, for example with energy-saving drives or explosion-protected systems. Gross sales amounted to approx. EUR 540 mn in the 2015 business year.

The company founded in 1965 now has over 36 subsidiaries worldwide. The closely meshed sales and service network ensures optimum availability for short delivery times and customer-oriented services. NORD produces a wide variety of drive units for torques from 10 to 200,000 Nm, electric motors with powers from 0.12 kW to 1,000 kW as well as the necessary power electronics in the form of frequency inverters and servo controllers. Inverter solutions are available for classical installations in the switch cabinet and for decentralised and fully integrated drive units.
