Especially for gantry systems, rapidly accelerating heavy loads can shoot the electrical power demand of frequency drives through the roof. At the same time while braking, regenerative energy is being put back into the drive system. For Ilsemann Automation, the challenge was to make the most effective use of the braking energy and to not dissipate it in braking resistors. In its retrieval robots for plastic processors, the company uses a drive solution from SEW-EURODRIVE that minimizes energy consumption, while at the same time boosting the operational reliability of the system.
In spite of advancing digitalization, the following still applies: Manual workstations are indispensable, because automation is not always profitable with small batch quantities or complex processes. Such workstations are preferred at the Martinshof Werkstatt Bremen, a sheltered workshop for a mixed workforce including people with handicaps, as they are ideally suited for integrating persons with physical or cognitive handicaps into working life.
A leading manufacturer of woodworking machinery is leveraging the benefits of the latest automation technology from Mitsubishi Electric.Fed up with the disadvantages of using automation products from a mix of different suppliers, Phoenix, USA-based Unique Machine & Tool Company wanted to find a reliable single-source supply partner. The OEM eventually settled on Mitsubishi Electric and, after initial success with VFDs, soon adopted servo motors, PLCs, cables and HMIs from the same supplier. Reliability and brand reputation have subsequently improved immensely, with Unique Machine today making '100% Mitsubishi Electric’ a major part of its sales presentations.
Three-phase power is often unavailable in rural and remote locations, which is a primary reason why farmers struggle to grow their operations. Any farm looking to run larger fans and motors to help increase storage and handling capacity have thus far been forced into using traditional solutions such as rotary phase converters, which are costly, have big capacitor banks and a high amp draw, running up electricity bills and erasing profits. Now, however, increasing numbers are turning to the latest Mitsubishi Electric variable frequency drives (VFDs), which allow a three-phase motor to run from a single-phase electric supply without a phase converter, facilitating greater power and lower energy consumption.
The application of e-F@ctory at Mitsubishi Electric’s Kani manufacturing facility, part of its Nagoya Works, Japan, has led to a number of hugely beneficial outcomes. For instance, by redesigning the process and reintegrating a human element where there was once 100% automation, a single line that previously occupied 280sqm has been reduced to a cell of just 44.1sqm. This 84% reduction in space means that the productivity of each square metre of production hall had been increased through greater utilisation.
