As global industries face mounting pressure to reduce energy consumption and optimize resource management, the demand for ultra-efficient drive technology has never been higher. Meeting this critical industrial need, system provider NORD DRIVESYSTEMS has officially announced the power expansion of its latest IE5+ motor generation.
At AarokaTech, we continuously track the innovations driving sustainable industrial automation. By extending the power capacity of its highly compact permanent magnet synchronous motors (PMSM) up to 11 kW, NORD is providing manufacturers and logistics centers with a highly scalable solution to drastically cut their operational carbon footprint while maximizing mechanical performance.
Unmatched Efficiency Across Wide Torque Ranges
The standout feature of NORD’s high-efficiency IE5+ permanent magnet synchronous motors is their ability to maintain a consistently high efficiency rating of up to 95% across a remarkably wide torque range. Unlike traditional industrial motors that lose efficiency outside their peak operational windows, the IE5+ generation delivers optimal energy consumption even during partial load and variable speed operations.
With this latest portfolio expansion, these advanced motors are now available in three distinct sizes. They cover a comprehensive spectrum of industrial applications, featuring:
- Extended Power Range: From 0.35 kW up to the newly introduced 11 kW.
- Continuous Torque: Ranging reliably from 1.6 Nm up to 43.9 Nm.
Streamlining Intralogistics Through Variant Reduction
Managing a massive industrial facility or intralogistics system often requires stocking and maintaining dozens of different motor variants. The IE5+ series addresses this administrative headache directly. Because these motors offer a high overload capacity, a large adjustment range, and constant torque over a wide speed range (up to 2,400 rpm), engineers can consolidate their drive systems.
Using a single motor model for multiple distinct applications leads to significant variant reduction. This dramatically streamlines manufacturing, logistics, spare parts storage, and field service processes.
“Particularly in spacious intralogistics systems with many drives and long operating times, this provides significant advantages,” emphasized Jörg Niermann, Head of Marketing at NORD.
A Holistic Approach to Sustainability: Energy and Material Savings
True industrial sustainability goes beyond just cutting the electricity bill; it must also account for the raw materials used to build the hardware. NORD’s new motor technology scores exceptionally well on both fronts.
“The efficiencies of our IE5+ motors significantly exceed the highest defined energy efficiency class, which considerably reduces their energy consumption and CO2e emissions,” Niermann added. “In addition, the holistic concept of our new motor technology combines energy and material efficiency, thus scoring twice in terms of sustainability.”
The engineering behind this involves an innovative 8-pole Interior Permanent Magnet (IPM) design. This highly focused magnetic field allows for a physical reduction in the size of the active motor parts. Consequently, NORD achieves massive material savings in the sheet metal package and the internal magnets. Furthermore, the stator is manufactured using a specialized “single-tooth winding” technique, which substantially reduces the volume of copper required in the winding head without sacrificing electromagnetic performance.
Modular System Solutions Tailored for Global Operations
Industrial environments vary wildly, which is why NORD DRIVESYSTEMS designs its solutions to be highly modular and suitable for worldwide deployment. The IE5+ motors can be precisely tailored to specific customer requirements.
Available configurations include motor-integrated encoders, integrated mechanical brakes, and a variety of specialized flange mountings designed for direct, seamless attachment to gear units.
Furthermore, NORD empowers users to assemble perfectly matched, end-to-end drive systems straight from their extensive modular catalog. Engineers can pair the IE5+ motors with advanced frequency inverters like the NORDAC ON, or couple them with high-durability UNICASE helical bevel gear units.
By transitioning to these highly integrated, ultra-efficient drive networks, industrial users benefit from vastly increased operational efficiency, a drastically reduced Total Cost of Ownership (TCO), and a remarkably fast Return on Investment (ROI).
