Bonfiglioli VF/W Series
Bonfiglioli VF/W Series are versatile universal worm gearmotors, engineered by the Italian power transmission specialist to deliver reliable performance across diverse industrial scenarios. Combining a robust worm gear unit with high-efficiency motors, this series stands out for its compact structure, patented technologies, and broad adaptability, making it a preferred choice for light to medium-duty applications worldwide.
Covering an extensive performance range, the VF/W Series spans a power output of 0.04kW to 75kW, with output torque ranging from 13Nm to 7,100Nm and transmission ratios from 7:1 to 300:1. Available in both single-phase and three-phase motor variants, it supports flexible speed regulation and is compatible with variable frequency drives (VFDs) for energy-saving operation. The core worm gear mechanism adopts high-quality materials—hardened steel worm shafts and bronze worm wheels—ensuring smooth meshing, low noise emission, and exceptional wear resistance for a prolonged service lifespan.
Equipped with patented design features, the series boasts a compact footprint that optimizes installation in space-constrained environments. Its robust housing, available in cast iron for heavy-duty use and aluminum for light-duty applications, offers IP56 as standard protection, with optional IP65/IP69K ratings to withstand dust, moisture, and high-pressure washdowns—ideal for food processing, chemical, and pharmaceutical industries with strict hygiene or corrosion resistance requirements.
The VF/W Series supports multiple mounting configurations, including foot, flange, and hollow-shaft installations, enabling seamless integration with existing equipment. Low maintenance requirements, thanks to optimized lubrication systems and sealed components, reduce operational costs. Widely deployed in conveyors, packaging machinery, mixers, and material handling equipment, it balances reliability, versatility, and cost-effectiveness, embodying Bonfiglioli’s commitment to engineering excellence.
