A drum motor is an integrated drive unit where the electronic motor, gearbox, and bearings are enclosed within the conveyor pulley.

Flat belts, modular belts, and certain fabric or rubber conveyor belts.

Interroll drum motors are used in food processing, packaging, logistics, airport baggage, warehousing and other belt conveyor applications where hygiene, reliability and compact design are important.

Highly efficient due to optimized power transmission and minimal mechanical losses.

Correctly dimensioned drum motors can drive horizontal, incline and decline belt conveyors, provided that belt tension and friction are properly calculated.

Interroll drum motors are equipped with integrated thermal protection and are designed to operate safely within defined load and temperature limits, helping to protect the motor and extend service life.

For high efficiency, precise speed control, and reduced energy losses.

Interroll offers low, medium and high power drum motors in various diameters and belt speeds to handle different load and throughput requirements.

Yes, drum motors with stainless steel housings and appropriate sealing are widely used in wash‑down areas because the enclosed design minimizes crevices and facilitates cleaning.

A drum motor integrates the motor and gearbox inside the pulley, reducing exposed components, saving space and simplifying cleaning, while external drives use separate motors, gearboxes and chains or belts.

Choose a drum motor when you use a belt conveyor or need a compact drive at the head of the conveyor, and motor‑driven rollers when your system is a roller conveyor requiring zoned control.

Drum motors often require less maintenance, have fewer external parts and can reduce cleaning time and energy losses, lowering operating costs over the life of the conveyor.

Yes, due to enclosed, easy-to-clean designs.
