Determination of Parameters of Symmetrical Six-Phase Permanent Magnet Synchronous Machines

This paper presents offline methods to determine different parameters of Symmetrical Six-Phase (SSP) Permanent Magnet Synchronous Machines (PMSMs). Accurate estimations of different parameters are crucial for proper machine modeling, control, and performance estimations. This paper discusses two offline methods to accurately determine different inductances and the stator resistance of SSP-PMSMs using a single-phase AC source. A method to calculate the Permanent Magnet (PM) flux linkage is also discussed. Machine parameters of a high-speed, low-inductance SSP-PMSM are determined using both methods. The determined parameters are compared with Finite Element Analysis (FEA)-based simulation results and the results are presented in this paper.
