NORD Extends IE5+ Synchronous Motor Line with New 112 Frame Size

Why It Matters

The SK 112 gives manufacturers a compact, ultra‑efficient high‑power option, cutting energy costs and simplifying system design, which accelerates ROI and supports sustainability goals.

Key Takeaways

• New SK 112 adds 15 hp to IE5+ line
• Efficiency reaches up to 95% across speed range
• Ventilated TEFC version supports continuous intralogistics duty
• TENV version offers IP69K for hygienic environments
• Integrated design reduces material use and CO₂ emissions

Pulse Analysis

NORD DRIVESYSTEMS' latest addition, the SK 112, pushes its IE5+ permanent‑magnet synchronous motor family into the 15 hp segment, filling a gap for compact, ultra‑efficient drives. IE5+ denotes performance that exceeds the EU's most stringent energy‑efficiency class, delivering up to 95 % efficiency even at partial load. By extending the frame range from 71 and 90 to 112, NORD gives system designers a broader power envelope without sacrificing footprint, a crucial advantage for space‑constrained automation and robotics applications where every millimeter counts.

The SK 112 inherits an eight‑pole interior permanent‑magnet (IPM) architecture that trims active parts, cutting sheet‑metal and copper usage while maintaining high power density. Two housing styles address divergent needs: a ventilated TEFC version with finned cooling for continuous‑duty intralogistics, and a smooth‑body TENV variant that can be sealed to IP69K for harsh, wash‑down environments such as food processing. Both configurations incorporate a standard incremental encoder and optional mechanical brake, ensuring precise control and easy integration with NORD's gear units and electronic drives.

From a business perspective, the new 112 frame translates into measurable cost savings. Higher efficiency reduces electricity bills and lowers CO₂ footprints, supporting corporate sustainability targets. Material‑efficient design and reduced part count lower manufacturing expenses and simplify logistics, accelerating time‑to‑market. Combined with configurable options—absolute encoders, flange mountings, and integrated brakes—customers can tailor solutions that minimize total cost of ownership and achieve rapid return on investment, reinforcing NORD's position in the competitive high‑performance motor market.
