Topology Comparison of Compound-Structure Permanent-Magnet Synchronous Machines

A compound-structure permanent-magnet synchronous machine (CS-PMSM) system is a hybrid-electric-vehicle power-train concept. Six typical topologies of CS-PMSMs are proposed. The characteristics of different CS-PMSMs are compared and evaluated from the aspects of torque density, manufacturability, he...

Description
Summary:A compound-structure permanent-magnet synchronous machine (CS-PMSM) system is a hybrid-electric-vehicle power-train concept. Six typical topologies of CS-PMSMs are proposed. The characteristics of different CS-PMSMs are compared and evaluated from the aspects of torque density, manufacturability, heat-dissipating capability, and magnetic coupling. The selecting principle of different topologies is proposed for practical application.
