Abstract

<abstract abstract-type="main"> <title>Summary</title> <p>A novel model of a variable‐speed drive system, consisting of a three‐phase induction machine fed by a matrix converter (MC) including its auxiliary circuits, is proposed in this paper. The main novelty of this model lies in the combination of a MC model created in the Matlab/Simulink environment with a finite element method model of an induction machine. The combined operation of these two components as an integrated model allows the detailed simulation of both the MC's and the induction machine's operation. The main advantage of this model is that the introduction of various manufacturing asymmetries and faults, both mechanical and electrical, in the induction machine structure is greatly facilitated. In that way, the created model can be used in order to examine in detail the consequences of these asymmetries or faults to the drive system's operational behavior. Additionally, it can be used for the development and/or evaluation of diagnosis methods for the detection of these faults under different operational conditions using motor current signature analysis, magnetic flux, speed or torque spectrum analysis and other methods.
