   Comparison of Magnetic Noise Compensation Techniques for Dual Three-Phase Electrically Excited Synchronous Machines
By Jonas HENKENJOHANN [View]
[Download]

Abstract: This paper presents a detailed comparison of two commonly known magnetic noise compensation methods. One is based on forces generated by harmonic currents interacting with the fundamental field,while the other uses a harmonic field. Both methods are applied to dual three-phase electrically excitedsynchronous machines. The required compensation currents and parasitic effects, such as the inducedvoltage in the field winding, are compared. Furthermore, known precalculation methods are adapted todual three-phase electrically excited synchronous machines and validated with FEM calculations.

   Double inverter concept for high-speed drives without motor filters
By Stephan BEINEKE [View]
[Download]

Abstract: It is known that high-speed machines have high power and loss densities. The additional losses inthe rotor caused by harmonics are particularly critical, as they act in the center of the machine. Thispaper shows an approach to reach small additional losses without a filter between inverter andmachine.
