AI-based app optimises energy use of drive systems

21 November, 2022

At the recent SPS show in Germany, Siemens unveiled an enhanced version of its Analyze MyDrives Edge app with an AI-based function that calculates the energy consumption of an entire drive system without needing extra sensors or measuring devices. The app shows how efficiently a drive is running, what its energy consumption and operating costs are, as well as its carbon footprint. It can be used to optimise drive settings.

Siemens says it is responding to the need for greater sustainability. While its Simotics SD IE4 motors already have efficiencies of up to 96% or higher, extra energy savings of up to 6% are possible with IE4 or even IE5 motors.

The key to higher efficiency lies in the interaction of the individual elements in a drive system from more efficient motors with variable-speed control, through digital components and tools, to the use of electrically buffered energy in the motor network. Together, these can achieve system savings of up to 60%, Siemens suggests. It adds that digitalisation will make a major contribution to increasing the energy efficiency of motor-driven applications in the future.

The Analyze MyDrives Edge app is part of Siemens’ new Xcelerator digital platform which aims to help users to accelerate their digital transformation.

At SPS, Siemens also launched a compact 250kW DC-DC converter with output voltages of up to 1.2kV for connecting batteries or ultracapacitors to industrial drives. The Sinamics DCP 250kW allows these energy storage devices to smooth load absorption from the grid, eliminating peaks. It can also make braking energy available in the DC system. With suitable system designs, the DC converters need fewer conversion steps. Power capacity can be expanded easily by connecting several converters in parallel.
