Increased awareness of environmental issues is a powerful argument for saving energy, but so is the constantly rising cost of electricity. Much modern plant and equipment holds an enormous amount of untapped savings potential. If this can be exploited it is not just the environment that stands to benefit, but the company as well. These factors help explain the trend towards energy-efficient drive systems.
The intelligent use of direct drives can, for example, save up to 40% of normal electricity costs. Some motor manufacturers, such as AMK, offer motors with sufficient power density and overload capacity to meet even the most stringent application demands.
Even at a more general level, direct drives can have a positive impact on costs. Water-cooling ensures virtually silent operation. Compact devices take up little space. Little to no maintenance ensures long service life and reduces costs.
Use of regenerative servo drives effectively addresses energy and cost issues, because the braking energy is recuperated and fed back into the power system rather than absorbed by a braking resistor. To facilitate the creation of robust systems, AMK offers AMKASYN KE/KW compact servo drives featuring harmonic system currents for supply and regenerative feedback.
These drives offer a controlled dc link that is impervious to supply faults. What’s more, the voltage boost in the dc link makes it possible to achieve a higher drive speed and output.
Increasing energy efficiency in plant and machinery ultimately comes down to one key factor: ensuring that you have the right drive technology and that it is used intelligently.
