Abstract

In this paper is presented the modeling and analysis of a six-phase induction machine considering
the space harmonic components. It is shown that the harmonic injection in phase voltages provides an increase
in torque, therefore, improving the torque density of the drive system. It is presented the machine dynamical
model, the steady state analysis and experimental results.
