Modeling of Novel Dual Three Phase PMSM with Pseudo-Triple Winding Structure and its Current Vector Control

In this paper, we propose the control model for a novel dual three-phase PMSM with pseudo-triple winding structure(DTP-PMSM with PTWS) which is one of the new multiple stator winding machines. The proposed control model is represented as the extended form of the conventional dual three-phase winding machine, and the validity is demonstrated by being compared with magnetic field analysis results. Furthermore, the current vector controller for the control model is designed and its performance is confirmed by simulation.

I. Introduction

As electrification advances in the mobile field, Multiphase machine is getting a lot of attention due to their advantages of lower torque ripple, higher output, higher fault tolerance, and higher control degree of freedom [1] – [7]. Especially, Research for dual three-phase winding machines has increased because it is able to cancel 6th-order torque ripple due to its structure. For example, there is research regarding coordinate transformation [8] - [9], improved torque density [10], improved fault tolerance [11] – [14], and so on.
