Single-phase open-circuit fault operation of bearingless multi-sector pm machines
2019 IEEE International Electric Machines & Drives Conference (IEMDC), 2019•ieeexplore.ieee.org
This paper investigates the single-phase open-circuit fault of a bearingless multi-sector PM
synchronous machine. The mathematical model of the suspension force and torque
generation is developed for both healthy and faulty conditions. The model is written in a
general form and it can be easily extended to any sectored PM synchronous machine. Then,
a fault tolerant control strategy is proposed and verified by means of finite elements and
numerical simulations. The system shows a good fault tolerant capabilities.
