Making efficient use of energy

AMK does not just focus on saving energy for the sake of the environment, but also aims to optimize the energy balance. In this respect, selection of the right components and their precise dimensioning have a decisive role to play. The key thing to realize is that it is not actually the purchase price that is crucial when considering costs, but the “life cycle costs”. Indeed, up to 90 per cent of the follow-up costs are spent on covering energy requirements. This clearly illustrates the huge potential savings that are waiting to be made with energy-efficient drives.

High output – Low consumption

Intelligent use of energy is the order of the day: AMK’s wide range of motors provides the perfect basis for getting the drive selection and dimensioning processes exactly right. The synchronous servo motors from the DYNASYN series are characterized by their high overload capacity and excellent efficiency. This efficiency can be boosted even further if a holistic view of the installation is adopted. Using the motor as a direct drive results in considerable energy savings, as it means that only active processes need to be supplied with power. Whether it is a question of replacing the hydraulics or cutting out the gearbox, the efficiency of the application is significantly improved.

Minimum effort – Maximum results

The energy that is put in must be exploited to the full: The KES servo inverters, which offer infeed/regenerative feedback functions, generate sinusoidal line currents. Thanks to the optimized power factor of 0.98, the incidental reactive power can be significantly reduced. As a result, substantial energy savings can be achieved in motor mode as well as in generator mode. What’s more, regenerative energy can even be fed back into the supply network.

Long service life – Huge potential savings

Energy usage must be viewed within the context of time: The Zentralverband der Elektrotechnik- und Elektroindustrie (Germany’s Electrical and Electronic Manufacturers’ Association) has calculated that energy costs can account for up to 90% of the overall follow-up costs of an installation. In essence, the follow-up costs are estimated to equate to between five and fifty per cent of the investment costs. Consequently, the costs incurred throughout the entire life cycle of a machine are a truly significant criterion for end users. If energy costs can be reduced, “TCO” (total cost of ownership) will also fall and the procurement price no longer carries anything like the same weight. AMK’s energy-efficient drive solutions are the key to unleashing potential savings throughout the entire life cycle.
