An Online Analytical Solution for Multi-Sector Bearingless Machine Current Reference Calculation

Résumé

In this paper, an online analytical current reference calculation for minimizing Joule losses in Multi-Sector Bearingless Synchronous Machine with power-sharing capabilities is presented. In this study, the optimization problem of determining the current references as a function of torque and radial forces, is solved analytically and compared with previously proposed numerical solutions. The proposed method significantly reduces the required data storage and computational burden, making it more suitable for real-time applications. Additionally, it improves the precision of current reference calculations, ensuring more efficient and balanced power distribution among multiple sectors. This advancement contributes to the overall reliability and performance of bearingless machine systems in high-speed and high-precision applications.
