M. Tech. Electrical Engineering. / Investigates the mathematical modelling, analysis and simulation of a six-phase squirrel cage induction machine. This dissertation is the report of the analysis and simulation of this machine through three methods, namely: The direct-quadrature axis (dqxy0102) based on generalised theory of electric machines, which enabled the machine to be mathematically modelled in the arbitrary reference frame; the classical magnetic field distribution analysis; and the finite element method (fem). The resulting models of the analysis of the six-phase squirrel cage induction machine are implemented by simulation using appropriate software. The simulations generate unique results of the steady-state and the dynamic performance characterising the performance of the six-phase squirrel cage induction machine. Tests are conducted on a 1.5 kW experimental machine whereby the performance characteristics of the theoretical analysis and simulations are validated with the experimental results. The results of the three are compared among themselves, and also with the experimental results to appraise the suitability of each method for the modelling and analysis of the hpo machine.Even though six-phase machine is considered in this study it is believed that the methods as applied in this work are generally applicable to hpo squirrel cage induction machine of any number of phases.
