Small step, big impact – 
Energy efficiency and dynamic performance

Siemens has expanded its portfolio of Integrated Drive Systems (IDS) to include a new drive series based on synchronous-reluctance technology. This motor technology sets itself apart as result of its very high efficiency. As an integrated drive system, the reluctance motor and inverter are specifically harmonized and coordinated with one another – and offer unrivaled cost-effective operation.

The highest efficiency drive system with system efficiency class IES2 guarantees maximum efficiency. This means that minimum operating costs are reached in processes that also require precise control. And finally, a high degree of productivity is guaranteed as a result of the high dynamic performance with short accelerating times and a low moment of inertia. Commissioning is simplified using predefined parameters in the form of a code on the motor rating plate.

How do you combine the highest efficiency with dynamic performance?

Proven products based on standard platforms are used together with integrated innovative technology. The converter motors with synchronous-reluctance technology have been specifically coordinated and harmonized with SINAMICS G120 converters, therefore creating an integrated drive system with the highest efficiency.

When compared to systems with induction motors, synchronous-reluctance technology sets itself apart as a result of the especially high efficiencies – especially in the partial load range – and the high dynamic performance.

In a first step, this innovative technology is available in the power range extending from 5.5 up to 30 kW. The motors are available with aluminum enclosure for general environmental conditions (SIMOTICS GP) – as well as in a cast-iron enclosure (SIMOTICS SD) to address demanding environmental conditions. The SINAMICS G120 vector control ensures an optimum operating response. It is especially simple to commission the drive system using the motor code on the motor rating plate.
