NORD DRIVESYSTEMS recently launched a synchronous motor which boasts a significantly higher energy efficiency (IE5+). This motor can be supplied with or without a fan. It is also suitable for wash-down and intralogistics applications when incorporating a nsd tupH surface treatment.
According to Managing Director for NORD DRIVESYSTEMS in Australia, Max Jarmatz, this latest generation permanent magnet synchronous motor has considerably lower energy losses than its predecessor, the IE4 series. “This unventilated smooth motor achieves a high efficiency which, at times, proves to be more efficient via a wide torque range,” says Max.
“It is optimally suitable for operation in a partial load range and the compact IE5+ motor offers a high-power density with less installation space required”.
Max notes that the IE5+ series will initially be launched in a size for power ranges from 0.25 to 1.1 kW, with a continuous torque from 1.6 to 4.8 Nm and speeds from 0 to 2,100 min-1. The motor can be directly mounted according to NEMA or IEC.
“We will gradually extend this motor concept to include additional sizes and powers based on demand and customer requirements” he explains.
A drive for hygienic requirements
The IE5+ is ideal for hygiene sensitive and harsh environments because it is easy to clean and wash down and is corrosion resistant. “A nsd tupH surface treatment and IP69K protection class is available as an option as well as an integrated mechanical brake”.
The nsd tupH surface treatment offered by NORD is an outstanding corrosion protection for gear units, smooth surfaced motors, frequency inverters and motor starters in wash-down optimised cast aluminium housings. The drives are easy to clean and largely resistant to acids and alkalis. It is even possible to use high-pressure cleaners or apply aggressive media. The fanless smooth surfaced motors prevent the spreading of germs and run very quietly.
Max concludes saying that, an integrated encoder also forms part of the standard equipment. “The new IE5+ motor can be combined with NORD gear units and drive electronics as a modular system and will be available from the second quarter of 2020” says Max.
