A limited short circuit current PM motor is studied based on the segmentation of the rotor magnets. The principle is to reduce the magnetic flux by means of magnets subdivision and an increase of rotor pole number. The effect of magnet segmentation on machine characteristics is analyzed using finite element method (FEM). The short circuit current of designed fault tolerant machine is well limited...
In this paper a simple dynamic model for a PMSM with inter-turn winding fault is derived. FEM is used for parameter determination of the machine with inter-turn fault. This fault model is used to study the behavior of the machine with inter-turn fault. The experimental test is conducted to validate the fault model for different levels of fault severity. The comparison of the results obtained by the...
