Efficient and economical solution for large loads

Heavy loads, high forces, long travel distances and lower requirements for precision and dynamics are characteristic of end-of-line packaging. By using decentralised drive solutions with controlled frequency inverters, cost advantages of up to 50 % can be achieved here, depending on the type of system and application.

Drives with centrally controlled servo motors are widely used in end-of-line packaging. However, in applications with high mass inertia or long travel distances - for example palletising, stabilising or handling - these are usually not absolutely necessary. Decentralised drive solutions, for example with controlled asynchronous motors, are an efficient and economical alternative here. NORD DRIVESYSTEMS knows exactly what the industry needs and implements modular drive concepts that are precisely tailored to the specific application and customer requirements.

Asynchronous motors with decentrally controlled frequency inverters

Due to their higher mass inertia, Nord asynchronous motors offer decisive advantages in end-of-line packaging. When moving heavy masses, they ensure better regulation and motion control than classic servo solutions, which have to be adapted to the application via a large transmission ratio. In addition, they enable maximum process stability, they reduce vibrations and the risk of damage to the load or the packaging machine. Another plus: asynchronous motors are available everywhere in a large selection as well as being maintenance-friendly and can be combined with different types of gearboxes and frequency converters.

When used with decentralised frequency inverters such as the Nordac BASE SK 180E, the FLEX SK 200E, the LINK SK 250E or the ON SK 300P, components such as control cabinets and cabling are also eliminated and the setup effort is significantly lower. Furthermore, the space saving is a significant advantage. With a modular concept, the drive also remains maximally flexible, because redesigns in the system architecture are possible at any time without major structural changes, and additional drives can be easily added later without changes to the control cabinet.

Cost advantages of up to 50

Lower procurement costs, constructive freedom in machine design, faster commissioning, simplified maintenance and servicing processes: Asynchronous motors with decentrally controlled frequency inverters and encoder feedback via absolute or incremental encoder enable both very economical and precise positioning applications and the dynamic movement of large and heavy packaging units. This makes this technology a real alternative for application areas such as end-of-line packaging, where large loads and high forces are the norm. Depending on the type of system and application, savings can be up to 50 %.
