Worm Gear Motors
NORD Worm Gear Motors are compact, self-locking transmission solutions designed for industrial applications requiring high torque density and space efficiency. Integrating a worm gear reducer with a motor, they feature a right-angle layout that simplifies installation in confined spaces, making them ideal for scenarios where spatial constraints and load-carrying capacity are critical.
The series covers a versatile performance range, with power outputs from 0.12kW to 15kW and output torque spanning 20Nm to 3,000Nm. Transmission ratios range from 5:1 to 300:1, supporting precise speed reduction for low-speed, high-torque operations. A key advantage is the inherent self-locking capability (depending on the worm lead angle), which prevents back-driving without additional brakes, enhancing operational safety in vertical or load-holding applications.
Engineered for durability, these gear motors adopt high-quality worm shafts and worm wheels—typically made of hardened steel and bronze, respectively—ensuring smooth meshing, low wear, and quiet operation. The robust cast iron or aluminum housing (for light-duty variants) provides excellent torsional rigidity and corrosion resistance, while advanced sealing systems prevent lubricant leakage and protect internal components from dust and moisture.
Widely applied in conveyors, packaging machinery, door systems, and material handling equipment, they offer easy integration with modular mounting options (foot, flange, hollow shaft). Compatible with variable frequency drives (VFDs) for flexible speed control, they require minimal maintenance thanks to optimized lubrication systems. With their combination of safety, compactness, and reliability, they deliver cost-effective solutions for both standard and light-duty industrial needs.
