Steady-state modeling and analysis of six-phase synchronous motor

Abstract

Steady-state analysis is needed for a better understanding of the operational behavior of a six-phase synchronous motor. Therefore, this paper primarily addresses the steady-state analysis of an asymmetrical six-phase synchronous motor, including the development of a mathematical model employing Park's (dq0) transformation, valid for different terminal conditions. These conditions include the motor operation with input supply at both sets of the three-phase stator winding as well as at only one set of the three-phase stator winding (motor-generator mode). A unified and simplified mathematical treatment along with its experimental results is presented.
