Two Design Procedures for PM Synchronous Machines for Electric Powertrains

This paper presents a design environment for permanent-magnet synchronous motors (PMSMs). Two design examples for electric vehicle (EV) traction are presented: one interior PM machine of the PM-assisted synchronous reluctance type and one concentrated-winding surface-mounted PM motor. The parametric design software used in this paper includes design equations, finite element analysis (FEA), and multiobjective optimization algorithms for the...
