In recent years, there has been an increasing interest in embedded applications, particularly fault-tolerant embedded systems. In this presentation, a flux-switching machine is studied, considering a 3-phase and a 5-phase machine. The study has been organised in the following way. First, fault-tolerant characteristics are discovered. Then, a stochastic exploration is carried out in order to compare the two machines. Finally, the two machines are experimentally tested in order to validate the previous concepts.
