Power-Sharing Control in Bearingless Multi-Sector and Multi-Three-Phase Permanent Magnet Machines

This article deals with the power-sharing control of bearingless multisector and multithree-phase permanent magnet machines. The proposed strategy allows to distribute power flows among three-phase inverters supplying machine during operation drive. technique is based on extension vector space decomposition modeling approach. components producing electromagnetic torque, i.e., q -axis currents, are controlled independently from xmlns:xlink="http://www.w3.org/1999/xlink">d ones, also aim managing systems. Conversely, currents exploited for generation radial forces needed levitate rotor, while considering compensation caused by in case unbalanced sharing strategy. validity method confirmed simulations experimental tests a prototyped synchronous machine. approach contribution development advanced systems employing multiphase drives field multiport applications.
