Interroll Drum Motors are mainly designed for use in belt conveyors and connected conveyor systems. Thanks to many years of experience in the belt conveyor sector, Interroll can offer a comprehensive range. Interroll Drum Motors enable the construction of maintenance-free, energy-efficient conveyor belt systems.

Drum motors are used in various areas:

  • in airport luggage conveyors
  • in the packaging industry
  • in the food processing industry
  • in the production and manufacturing sector
  • for dynamic weighing

Drum Motor benefits

More options, one drive solution: An extended number of gear stages broadens the range of speeds so that one drive solution is sufficient for all current and future uses. Furthermore, all options like encoders, brakes, or backstops are available for all motors.

More performance, more configurations: The extended range of variants for the motors from 40 W to 1100 W covers all conceivable uses in the food industry, material handling, and manufacturing.

Tested quality, innovative technology: All motor components are standardized, and thoroughly tested. For our customers this means shorter delivery times.

Simplified construction, more service, lower costs: Since all motors have the same shafts, the variety of parts is reduced to a Minimum, resulting in a fundamentally easier conveyor construction - no matter if a synchronous motor or an asynchronous motor is needed. Replacement parts are available worldwide through Interroll and service partners provide fast and professional repairs.

Flexibility: watch the animation

More stable: The 30 mm shaft on Interroll’s new drum motors is significantly stronger, allowing for higher belt Tension as it does not bend even under higher load and at the same time, protects the ball bearings. The customers is on the safe side even with a non-optimal belt tensioning.

Reliable operation: A stable planetary gear box allows a high torque in all motors, holds up against bending, and resists against overload and impact load. The result is safer, more reliable operation.

Certified quality: All critical components and mechanical connections have been subject to stringent and comprehensive endurance testing. Our engineering laboratory's expertise has been confirmed by practical tests with customers.

Robustness: watch the animation

All drum motors in the new generation meet the highest requirements and are fitted with the highest degree of IP69k protection, which makes cleaning the facility much faster and easier and also reduces the risk of product contamination in the food processing area.

The PTFE-sealing allows a high pressure cleaning with chemicals according to ECOLAB specifications.



Ultra-hygienic: watch the animation

The new drum motor platform is not only easy to operate but also to install, mount, and maintain. The plug-in cable connection serves as a true plug-and-play solution for faster, easier initial installation, maintenance, and repairs.

Complete disassembly is not needed for motor maintenance or the replacement of a damaged cable. Customers save time, lower costs and reduce potential downtime.

Plug-and-play: watch the animation

The modular design of the drum motor allows a free combination of individual module groups, such as shaft, end cover, shell, steel or technopolymer gear, asynchronous or synchronous motor winding, to perfectly and cost optimized meet the requirements of an application.
