BMG has introduced the new NORDAC FUSION – a compact drive system, which combines a motor with a decentralised frequency inverter. This simple, quick and efficient system is the solution for anyone who requires maximum drive power in a confined space.
“This high-performance matched package has been developed by Getriebebau Nord for use on automated conveyor lines with multiple drive points, to enhance efficiencies and reduce the work of specifying and commissioning each drive,” explains Barry Stoltz, BMG’s Head of Operations – Drives (Gears|Motors|Electronics).“Users benefit from a compact, ready-to-use system that operates reliably once connected. BMG specialists match the motor and inverter mechanically and electrically and configure the drive parameters in advance. Optimal electrical and mechanical adjustment of the motor and inverter achieves high power density.”
NORDAC FUSION’s decentralised design enables mounting the inverter directly on the motor, which means centralised control cabinets are no longer required and wiring efforts are considerably reduced. Power and communication cables plug into the unit, simplifying installation at conveyor and transfer points. The matched system is available from BMG in units from 0.31 to 3.7 kW.
The NORDAC ON inverter pairs with an IE3 asynchronous motor for standard conveying, while the NORDAC ON+ pairs with an IE5+ permanent magnet synchronous motor. A gear unit from NORD’s modular range can be added to suit specific application requirements.
For more dynamic duties, the IE5+ motor can be controlled without a separate encoder. The inverter uses CFC open-loop injection to estimate rotor position and speed from the motor’s electrical response. Motor efficiencies of up to 95% with IE5+ technology can be achieved over a broad torque range. In partial load and partial speed ranges, this system offers optimum energy consumption performance and allows for a reduction of variants for more streamlined production, logistics, warehousing and service processes.
The inverter has an integrated programmable logic controller for drive-related functions. The Ethernet interface can be configured for PROFINET, EtherNet/IP or EtherCAT, allowing the same drive design to be used on lines with different control networks.
Depending on the inverter configuration, functional safety features include safe torque off and safe stop 1. An optional safety module enables communication via PROFIsafe or FSoE.
For food-processing lines that require wash-down, NORD pairs an unventilated IE5+ motor with the NORDAC ON PURE inverter in a configuration with NXD tupH® surface protection. Hybrid cabling and daisy-chain connections can simplify the wiring layout around equipment that needs regular cleaning.
NORD systems are easy to expand or upgrade, using a minimum of different types and sizes of components. Local assembly at BMG World in Johannesburg enables prompt delivery of drive systems and the quick availability of spare parts.
BMG’s team of technicians offers a technical advisory and support service, which is tailored to meet the specifications of contractors, designers and the end-user throughout Southern Africa.
