Shelby Township, MI 48315
Designing and manufacturing drum motors in USA and Canada for over 35 years, VDG provides reliable conveyor drive solutions to material handling and processing industries through innovation, research and development, and precision manufacturing.
The streamlined VDG Drum Motor has all drive components including motor and gear reducer inside the drum for a safer, more efficient, and space optimized belt conveyor drive solution. All components are designed for 80,000 hours of continuous operation before maintenance, minimizing downtime, and reducing maintenance and operating costs.
The VDG patented IronGrip™ lagging available for the drum motor provides 40% more traction than standard rubber lagging, allowing for less pre-tensioning while providing higher belt pull. The IronGrip™ system is composed of steel bars welded symmetrically on the drum with hot-bond vulcanized lagging inserts between the bars, eliminating lagging delamination, reducing wear of the belt and lagging, and extending the life of the conveyor.
The USDA approved SSV Sanitary Drum Motor is the most hygienic drive solution for food processing belt conveyors. It features IP69K rated sealing system and withstands up to 3,000 psi washdown pressure. The SSV Sanitary Drum Motor with the belt profile machined directly onto the 316 stainless steel drum drives modular, wire mesh, and monolithic thermoplastic conveyor belts without the use of sprockets. The sprocketless drum motor eliminates gaps and crevices where food by-products buildup, reducing water and time for washdown by 50%.
The new permanent magnet IntelliDrive™ drum motor delivers over 40% increased electrical efficiency and performance, much wider belt speed selection without loss of torque or belt pull and significant increase in electric motor lifespan, compared to a traditional induction motor. With all drive components housed internally, the IntelliDrive™ achieves 96% mechanical efficiency, further decreasing energy consumption and cost. The IntelliDrive™ enables onsite diagnostics, provides motor data feedback, full motor indexing speed control and communications with other plant equipment.
