Nord Introduces Power Extension for High-Efficiency Drive
With its latest IE5+ motor generation, system provider Nord Drivesystems offers high-efficiency solutions to reduce energy and resource consumption. The company has extended the power of its compact permanent magnet synchronous motors to 11 kilowatts (kW).
Nord’s high-efficiency IE5+ permanent magnet synchronous motors (PMSM) are characterized by a constantly high efficiency of up to 95% over a wide torque range. They achieve an optimum energy consumption performance in partial load and speed ranges. The motors are now available in three sizes, and their extended power range from 0.35 kW to 11 kW and continuous torque from 1.6 Nm to 43.9 Nm.
The high-overload capacity, the large adjustment range and the constant torque of the IE5+ motors over a wide speed range of up to 2.400 rpm enable variant reduction.
“Particularly in spacious intralogistics systems with many drives and long operating times, this provides significant advantages,” said Jörg Niermann, head of marketing at Nord. “The efficiencies of our IE5+ motors significantly exceed the highest defined energy efficiency class, which considerably reduces their energy consumption and CO2e emissions.”
The permanent magnet synchronous motors feature eight poles in an innovative IPM design. This allowed a reduction in the size of active motor parts.
The stator can also be manufactured with the single-tooth winding, which reduces the use of copper in the winding head.
