The paper presents an analysis of influence of selected fault states on properties of brushless DC motor with permanent magnets. The subject of study was BLDC motor designed by the authors for unmanned aerial vehicle hybrid drive. Four parallel branches per each phase were provided in the discussed 3-phase motor. After open-winding fault in single or few parallel branches, a further operation of the...
Diagnostic method of electrical faults in switched reluctance motors (SRM) based on current harmonics analysis is presented in this paper. The classification of electrical faults in SRM's has been discussed, simulation model and laboratory setup presented. For the SRM motor of 6/4 design the conclusions drawn from the tests conducted both in the simulated and laboratory conditions for regular operation...
