In this paper, two topologies of PM motors are studied and optimized to be suitable for direct drive propulsion of electric vehicle. Flux weakening strategy is used and optimal parameters of the motors are defined. The design of the machines is focused the quality of back EMF waveforms and external parameters. The first topology is a surface mounted motor (non-salient pole motor) with segmented magnets...
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...
A time stepping FEM analysis is performed for fault study of PM motor with inter-turn fault. FEM is used for magnetic field study and identification of the machine parameters. Novel analytical expressions are presented and validated for calculation of inductances based on field calculation. Finally, the developed fault model is used to study the PM machine behavior under different fault conditions.
