This paper presents a modeling approach and a fault index analysis of a voltage-source brushless DC motor. First, an analytical multi-physical model of the inverter-fed Permanent Magnet DC motor is developed and simulated using Matlab/Simulink. This model enables the generation of electrical, magnetic and vibration signals under healthy and faulty motor behaviors, with several fault categories and severities. Before simulating faulty conditions in the different parts of the analytical model, they are compared to Finite Element models, developed using Matlab for air-gap flux density and ANSYS software for stator natural frequency calculations. Simulation results of the motor during normal functioning and under faulty conditions are presented. In particular, rotor eccentricity and single pole demagnetization faults are studied in this paper. Then, different features, including time-, space-, frequency-and harmonic-domain characteristics, are extracted from vibration signals for different cases. Finally, these indicators are analyzed with respect to the fault severity to select the most discriminative one(s) allowing an efficient fault detection and isolation.

“…Among these models, Finite Element Analysis (FEA) is widely used to analyze the operation of the machine due to its accuracy and reliability. In [1], the performance of a PM machine is analyzed in the presence of a crack in the PM. A computational time reduction methodology based on field reconstruction has been proposed to study the electromagnetic vibrations and torque ripples in PM machine with a partial DF [2].…”

Various factors can lead to the demagnetization of permanent magnets, such as excessive magnetomotive force and/or high operating temperatures. As a result, the machine's flux density distribution is no longer uniform, producing new fault harmonics and reducing motor efficiency. In view of this problem, this paper presents the behavior of an external rotor permanent magnet synchronous machine in the presence of a total demagnetization fault in two adjacent magnets. The machine's performance will be evaluated using an analytical model that has been developed. Finite element analysis and experiment tests are used to validate the feasibility of the proposed analytical model.
