This paper proposes a reliability modeling method for induction motor drives based on an equivalent dq0 circuit model. The machine input voltages or currents are modeled as sources dependent on states and commands. This enables reliability analysis for different control strategies. The method utilizes failure modes and effects analysis, Monte Carlo simulations, and Markov models. Different controllers,...
In this paper, the effects of certain component faults on the performance of three-phase inverter-fed induction motors are analyzed under indirect field-oriented control. Simulations of faults in the current sensors, speed encoder, three-phase inverter, and motor are presented. Sample hardware faults verifying the simulation results are also presented. Performance requirements are set based on typical...
