Rotating electrical machines can be found in many sectors of industrial production. For decades, rotating electrical machines have been a central component of numerous applications. Climate change is now accelerating the use of these machines in areas where they were not previously found. Variable-speed drives in particular are becoming increasingly important. By using electric drive systems, the carbon footprint can be sustainably improved and regulatory and administrative requirements can be met.

The innovative electric drive concept presented here takes account of speed variability, digital penetration of the machine right down to winding level and the resource-saving use of materials. This is achieved through the complete integration of power converter and machine. In this drive system, the power converter, rotating electric machine and the software for operating the hardware components can no longer be viewed separately from each other. The machine and power converter are to be seen as an integral functional unit. The software controls, regulates and analyzes the integrated drive system, whereby the spatial and temporal shape of the air gap field can be freely defined and configured by the software.

The integrated drive system is suitable for a wide range of applications. The compactness of the drive, the adjustment of the machine performance via software and the comprehensive digitalization of the drive system are particularly noteworthy. An easily scalable modular system can be defined for the drive, which minimizes the use of materials and maximizes efficiency. This enables a wide range of drive tasks for a wide range of applications, reduced material usage and climate-friendly operation thanks to software optimization.
