Providing a robust, high-performance belt conveyor drive solution, Interroll’s 8.5-in. diameter drum motor is designed to manage medium and heavy unit load applications. The 220 Series drum motor features an internal gearing system with 97% efficiency and uses less power than many conventional drives. When fully loaded, the 220 Series uses 32% less power than equivalent gear motor drives, reducing energy costs and carbon footprint. The 220 Series is a self-contained unit with the motor, gearbox and bearings enclosed in a steel shell, protecting internal parts from contaminants.
