A drum motor (or motorised pulley) is 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 realised 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 checkstands, food processing conveyors and weighing equipment.

Famous quotes containing the words drum and/or motor:
“If all would lead their lives in love like me,
Then bloody swords and armor should not be;
No drum nor trumpet peaceful sleeps should move,
Unless alarm came from the camp of love.”
—Thomas Campion (1567–1620)
“We disparage reason.
But all the time it’s what we’re most concerned with.
There’s will as motor and there’s will as brakes.
Reason is, I suppose, the steering gear.”
—Robert Frost (1874–1963)
