Standard Series Drum Motor

The VDG Drum Motor is a one-component conveyor drive where the motor, gear reducer and all moving parts are enclosed inside the drum. The motor and gear reducer operate in a sealed oil bath, ensuring proper lubrication and cooling. The compact design of the drum motor provides space savings, efficiency and reliability when compared to traditional external conveyor belt drives.

VDG also offers the IntelliDrive™ Drum Motor featuring permanent magnet (PM) motor technology, providing a wider range of belt speeds and a significant increase in energy efficiency and cost savings.
