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.

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.
