An analytical modelling technique to calculate the generated magneto-motive force (MMF) and back-EMF of fractional slot concentrated wound (FSCW) permanent magnet synchronous machines (PMSMs) is reported. The generated MMF of a FSCW stator is analyzed and modelled using a Fourier series technique. General expressions of the harmonic winding factors for FCSW stators with different slot-pole combinations...
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 application of concentrated windings in permanent magnet machines significantly reduces overall machine length, due to the elimination of end winding overlap making it more suitable for areas with space limitations. Efficiency is also increased due to the reduction of copper loss. In order to take full advantage of these benefits, optimization strategies have been implemented and its effects are...
