Abstract	The increasing applications of permanent magnet electronic commutated motor (Brushless DC Motor) has motivated us to study the performance of this motor applied to naval propulsion and submitted to the following fault conditions: - Short circuit at one phase - Fault in current semicycle inversion at one phase - Fault at one or more inverter module opening the corresponding phases. The analysis is based on a prototype of 75 kW, constructed with similar characteristics of converter fed permanent field motor presented at Munich ICEM 86 by H. Fürsich and at Aachen EPE 89 by J. Saint Michel, and a simulation of a mathematical model developed using TUTSIM program for comparison between experimental and theoretical results. The aim is to quantify the advantage of the construction form with independent phases in order to avoid motor stopping in case of faults, relating with control methods to minimize the effects of these faults during motor operation in various load conditions and speeds, e.g., pulsating torques, reduction of power.
