Design of IPM machine with concentrated windings for vehicular applications

Due to limited space availability in vehicular applications, machines with high torque density are required. One of the ways to maximize space is by reducing machine end winding length and increasing its effective stack length. This paper illustrates a general design process used for implementing non-overlapping concentrated windings an interior permanent magnet (IPM) machine for field weakening applications. The model´s parameters and performance characteristics is studied in Flux2D. Additionally, a size constrain based on two available UNSW distributed winding IPM machines is set so as to compare torque density and field weakening capability of this proposed design.
