Permanent magnetic machines have attracted a lot of attention in various applications due to their high torque density, high power density and high efficiency. With the development of industries and the increase in the use of electric machines, another type of permanent magnetic machines with axial flux structure (AFPM) was proposed. in recent years, one of the new structures introduced for this type of machine is the RWAFPM, which has many advantages. But in many critical applications such as aerospace, ships, electric vehicles, wind turbines, etc., the reliability of the electric machines used in them is very important. one of the most important factors in the reliability of electric machines is their fault tolerance ability. For this reason, much research has been done in recent years to improve fault tolerance in permanent magnet machines. Therefore, in the present study, an attempt has been made to look at the issue of fault tolerance from a quantitative point of view and by introducing the indexes of fault tolerance, a good criterion for measuring and comparing the fault tolerance of different machines has been obtained. Then, by simulating the 3D FEM of the machine, modeling the various faults and calculating these indexes, the fault tolerance ability of RWAFPM machine has been investigated.
