Due to their high inertia, Nord’s asynchronous motors offer decisive advantages for end-of-line packaging systems. The motors are designed for use with Nord’s full line of gear units and variable frequency drives. When it comes to moving heavy loads, asynchronous motors deliver a higher level of control and movement than conventional servo solutions that require adjustment to the application via large gear ratios. They also provide higher process stability, quiet operation, and reduce vibrations along with risk of damaging the loads or packaging machines.
Nord’s decentralized variable frequency drive options include the NORDAC BASE, NORDAC FLEX, NORDAC LINK, and NORDAC ON/ON+. These electronic control products can efficiently control conveyor speeds, manage individual product placement and pickup, and smoothly operate palletizing machines without slowing product flow. Along with their high performance, Nord VFDs offer flexibility as the modular design concept allows changes and maintenance to take place at any time without large structural modifications, extensive downtimes, or changes within a control cabinet. The decentralized solution also saves on space as the VFDs can be directly mounted to the motor without need of a full control cabinet setup or extensive wiring system.
Depending on the system type and application, Nord decentralized variable frequency drives paired with asynchronous motors can amount up to 50% savings compared to the legacy design.
