Interroll RollerDrive EC310 – an energy efficient all-purpose drive

21 June 2012

The new 24Vdc Interroll RollerDrive EC310 supports the design of safe, cost effective, custom built, versatile conveyor and assembly lines. The drive uses up to 30 percent less energy and recycles brake energy. Thanks to its simple control technology and coordinated functions, the space-saving EC310 significantly simplifies zero line pressure accumulation conveyor technology compared with conventional systems.

The unit can be integrated seamlessly into new or existing logistics systems, and all elements of the system can safely operate in ambient temperatures between 0°C to 40°C, protected to IP54 or IP66 as required.
The EC310 conveyor drive offers outstanding torque at all speeds with excellent acceleration/braking performance, optimum energy-savings, low operating temperature and superb start-stop performance for all unit load handling applications, including food industry and packaging, as well as checkweighers and logistic applications.

Thanks to the new generation of control technology it has been possible to combine all of the components in one functional unit to create an environmentally-friendly system that enables customers to reduce costs and at the same time enhance the functional quality of their system.

The typical operation of zero pressure accumulation conveyors with RollerDrives is also extremely energy-efficient. Individual conveyor modules only run when there are containers present; once these have been moved off, the conveyor modules no longer run but continue to be ready for transporting product. This compares favourable with a typical zero pressure accumulation conveyor with a flat belt or line shaft, which has much higher energy consumption and noise emissions.

The RollerDrive EC310 is ideal as a drive for all zero pressure accumulation conveyor applications for use with lightweight to heavyweight containers. The versatility of the electronically commutated drive roller with its compact integral 24Vdc motor, electronics and gears, makes the planning, construction and operation of systems much simpler.

The unit has nine gear speeds, enabling the drive to be adapted ideally to all applications. A integral controller guarantees a constant conveyor speed in the specific load-bearing area. When the material being conveyed brakes, the EC310 feeds back energy, not only improving the energy balance of the system and reducing costs but also ensuring that the motor heats up less in operation. However, thanks to the incorporation of brake choppers and 'ZoneControls', voltage feedback is restricted to a non-critical level.

Depending on the design and complexity of a system, RollerDrive EC310 can be used with modules DriveControl 20 & 54 or ZoneControl for controlling the speed, direction of rotation and logic. The Interroll BusControl, currently in development, will enable remote control and monitoring of all conveyor system parameters.
