Stability analysis of an asymmetrical six-phase synchronous motor

Authors: ARIF IQBAL, GK SINGH, VINAY PANT

Abstract: This paper deals the stability analysis of a six-phase synchronous motor using eigenvalue criteria from its linearized model, so that the small displacement stability during steady-state condition can be accessed. Eigenvalue provides a simple but effective means for the stability analysis of a motor. An association between eigenvalues and motor parameters has been established, followed by the formulation of transfer functions and plotting the root locus of system, employing the dq0 approach in the MATLAB environment.

Keywords: Six-phase synchronous motor, stability analysis, linearized model
