Drum Motors (or motorized pulley) are a geared motor drive enclosed within a steel shell providing a single component driving pulley for conveyor belts. The drum motor concept was first recorded in 1928 but was not realized until the early 1950s when it was first produced specifically for conveyor belt applications. The idea was to produce a compact, totally enclosed single component drive unit with high efficiency and lower frictional losses than a conventional geared motor. The new design was quick and easy to install, required no maintenance and because of its totally enclosed hermetically IP66 sealed design would be unaffected by dust, dirt grease or water. Today you see many examples of drum motor applications in Airport check in conveyors and security machines, supermarket check stands, food processing conveyors and weighing equipment.
Test results showed drum motors used 32% less energy (unloaded) and 47% less energy (loaded) than a comparable geared motor drive thus helping to reduce the global carbon footprint. Drum motors have fewer frictional losses and a higher efficiency than conventional drives use in material handling industry, which normally transfer approximately 75% of their mechanical efficiency to the belt, compared to the Drum Motor which transfers up to 97%.
