NORDAC Fusion Combines Motor, Inverter Into Compact High-performance Unit

With NORDAC FUSION, NORD DRIVESYSTEMS launched a powerful drive system that combines motor and inverter into a compact unit.

Thanks to the optimal electrical and mechanical adjustment of both components, NORDAC FUSION achieves high power density, while keeping the installation space as small as possible. Users benefit from a ready-to-use system that operates reliably once connected. This eliminates extensive parameterization or time-consuming selection of components. 

For logistics projects with a high level of automation, this means less engineering efforts per drive axle, faster commissioning and consistently high drive quality. NORDAC FUSION’s decentralized design allows for direct mounting on the unit. Centralized control cabinets are no longer required and wiring efforts are reduced.

NORDAC FUSION combines asynchronous motors (IE3) and permanent magnet synchronous motors (IE5+) in ventilated and unventilated versions with a decentralized NORDAC ON frequency inverter. The optimized motor/inverter combinations cover a power range from 0.31 to 3.7 kW. They feature consistent safety and communication properties, are suitable for worldwide use, and can be complemented with a gear unit from the manufacturer’s modular product range.

The decentralized frequency inverters are characterized by their compact design, full plug-in capability and high reliability. Special features include the integrated PLC and their multi-protocol Ethernet interface.

PROFINET, EtherNet/IP and EtherCAT can be set via parameters. Integrated safety functions enable safe operation of almost all motion sequences in automated production.

Apart from STO and SS1, the NORDAC ON series will also feature the motion monitoring function SLS, SMS or SSM for fail-safe control of the rotary movement. They can be integrated via PROFIsafe or FSoE into a fail-safe application within an existing industrial Ethernet network. Stand-alone use is also possible. The safe digital inputs and outputs can be used to incorporate fail-safe peripheral components or functions. Emergency stop buttons, safety door switches, photoelectric sensors, etc. can be connected directly. Two safe single-channel digital inputs can be combined into one safe two-channel digital input, and two safe outputs can be combined into one safe two-channel output. The level of functional safety can be individually set with NORDAC FUSION as well.

Another advantage is the encoderless control of NORDAC FUSION with the manufacturer’s IE5+ synchronous motors (PMSM). Using the CFC open-loop injection method, the motor’s rotor position and speed can be captured without additional sensors. 

NORD’s IE5+ permanent magnet synchronous motors (PMSM) are characterized by a high efficiency of up to 95% over a wide torque range, according to the company. In partial load and partial speed ranges, they achieve optimum energy consumption performance and allow for a reduction of variants for more streamlined production, logistics, warehousing and service processes.

The NORDAC FUSION drive solution can be used up to a temperature of -30 °C. The combination of IE5+synchronous motors and NORDAC ON PURE with NXD tupH is suitable for wash-down applications in the food sector. Ethernet on board, hybrid cables and daisy chain technology enable efficient and hygienic topologies that are streamlined and easier to clean.
