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.

Yes, drum motors can be used in incline and decline conveyors because they provide sufficient torque and can be equipped with brakes or backstops for controlled operation.

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.

Synchronous drum motors should be chosen when high efficiency, dynamic performance, precise control, or frequent start stop operation is required.

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.

A drum motor should be chosen instead of motor driven rollers when driving belt conveyors that require higher torque, continuous power transmission, or hygienic design.

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.

Interroll drum motors stand out through their modular platform design, a high level of standardization, global availability, and consistently reliable performance. They are widely recognized for their efficiency, durability, and dependable operation across a broad range of applications.

Yes, Interroll provides global service and repair support through a worldwide network and spare parts availability, offering inspection, repair, and replacement solutions to maximize uptime and ensure reliable operation.

Technical documentation for drum motors can be found in the product catalog, user manual and on the Interroll website, including detailed specifications, wiring diagrams, certifications and selection guidelines.

The optimal drum motor configuration is determined based on factors such as belt type, required belt pull, conveyor speed, and width, supported by tools like our Belt Drive Matchmaker and selection diagrams. Contact us for expert guidance on power, torque, belt selection, and hygienic requirements.
