WAREHOUSING HANDLING & STORAGE C
onsumer behaviour has considerably changed in recent years. Many people buy clothes, toys or other convenience goods online. E-Commerce is booming and so is warehouse automation. Flexible warehouse systems are also in demand in large grocery chains warehouses, and require environmentally friendly, sustainable and intelligent drive concepts. The drive specialist NORD DRIVESYSTEMS is
highly familiar with the industry’s requirements and offers a variety of dynamic drive solutions which are suited for various applications and requirements in warehouse logistics: be it conveyor, palletising and winding technology via overhead conveyors or transfer trolleys and sliding shelves. “Drive concepts with integrated Ethernet interfaces are particularly in demand and are thus ideally equipped for integration into modern automation systems”, explains Gernot Zarp, Managing Director of NORD DRIVESYSTEMS. “We provide service-friendly plug-and-play solutions that are also characterised by predictive maintenance and condition monitoring concepts to increase the system availability and to avoid downtimes.”
THE SOLUTION FOR WAREHOUSING NORD offers customised drive solutions for warehouse logistics for an optimum compromise between investment, operating and maintenance costs. With motor efficiency class IE4 and system efficiency class IES2, the drive units achieve excellent efficiencies – especially in the partial load and speed range. The latest generation IE5 permanent magnet synchronous motors achieve an even higher energy efficiency and significantly reduces the energy consumption. The constant torque over a wide speed range allows for a targeted version reduction. This minimises administrative expenses, and enables leaner manufacturing, logistics, storage and service processes.
Utilising the high overload capacity of the motors and the wide adjustment range, the drives can be individually tailored to the system’s particular load range. IE5+ synchronous motors can be modularly combined with all gear units and drive electronics from NORD DRIVESYSTEMS. They combine the benefits of the modular system and the higher efficiency with the possibilities of reducing versions – the purchase thus pays for itself within a short time.
ENERGY-EFFICIENT AND POWERFUL The IE5+ motor achieves its high efficiency via a wide torque range, making it optimally suitable for economic operation in the partial load range. It offers a high power density with less installation space. For example, a size 71 motor can save up
to 40 percent of space compared to conventional asynchronous motors while a more powerful motor with higher energy efficiency can be integrated into the same installation space. Size 71 for power ranges from 0.35 to 1.1 kW
with a continuous torque of 1.6 to 4.8 Nm has already been on the market since 2020. Now size 90 expands the NORD portfolio with a continuous torque of up to 18.2 Nm or a power range of up to 4.0 kW. The IE5+ synchronous motor is available in both ventilated and smooth, unventilated versions. If required, it can be provided with a very smooth surface or can be combined with the nsd tupH surface treatment. Together with the decentralised NORDAC ON frequency inverter, the user gets an optimal system solution from a single source in which all components are seamlessly matched.
THE DECENTRALISED NORDAC ON FREQUENCY INVERTER The decentralised NORDAC ON frequency inverter has been developed for horizontal conveyor technology requirements in warehousing, and the NORDAC ON+ variant for interaction with the new IE5+ synchronous motor. It is characterised by an integrated Ethernet interface, its ease of maintenance through complete pluggability and an extremely compact design – providing an economical and intelligent plug-and-play solution for IIoT environments. The compact, smart frequency inverter for decentralised use can be mounted directly on the geared motor. It covers lower power ranges of up to 2.2 kW and has an energy-saving function in the partial load range. The NORDAC ON is equipped with a flexible
Ethernet interface to map different protocols such as EtherCAT, Profinet or EtherNet/IP. There is no need for various hardware versions, and protocol adjustments can be conveniently implemented via parameter settings of the Ethernet stack. Updates can also be implemented quickly and simply via Ethernet; the need for manual on-site firmware installation on the individual drives is eliminated. The maintenance effort, in particular for large systems, is thus significantly reduced. Thanks to the stack, the need for further micro controllers is eliminated, heat losses are lower and the inverter size is reduced. The more compact the combination of inverter and motor, the easier the embedding into a conveyor belt. For small and medium-sized product and packaging units, this is a distinct competitive edge.
COMPACT SYSTEM SOLUTION FOR CONVEYOR TECHNOLOGY NORD also presents a new space-saving and user- friendly drive solution for conveyor technology that allows for the significant reduction of versions in a system. The innovative system solution comprises an IE3 87 Hz motor with a 350
