Helical Inline Gear Motors
Helical Inline Gear Motors are integrated, coaxial transmission solutions that combine motors with helical gear reducers, renowned for compact structure, high efficiency, and stable operation. Their helical tooth design enables gradual meshing, distributing loads evenly across multiple teeth to minimize noise, reduce vibration, and achieve transmission efficiency of 94%-98%, making them ideal for 24/7 continuous industrial operations.
As a global drive technology leader, NORD offers three core series to meet diverse application needs. The STANDARD series, a reliable classic with 6 sizes, covers 0.12kW-7.5kW power and 50Nm-700Nm torque, featuring torsionally rigid cast iron housing for durability and low maintenance. The UNICASE series, with 0.12kW-160kW power and 10Nm-26,000Nm torque, adopts one-piece housing technology to eliminate oil leakage, ensuring stability in medium-heavy duty work.
The NORD BLOC.1 series, tailored for food and pharmaceutical industries, has 0.12kW-37kW power, hygienic aluminum housing, and optional IP69K wash-down capability. All variants support 2-3 stage reduction with a 1.35-14,340.31 ratio range, and offer flexible mounting (foot, flange, hollow-shaft) for easy integration.
Precision-machined hard teeth (HRC58-62) and reinforced bearings enhance load capacity, adapting to harsh environments. Compatible with VFDs for precise speed control, they adopt modular accessories and long-life lubrication systems, extending maintenance intervals. Widely used in conveyors, packaging, and food processing, they deliver cost-effective, reliable drive solutions.
