Abstract

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. Index Terms-Bearingless machines, multiphase machines, PM synchronous machines, fault tolerant control.
