Analysis of MMF and back-EMF waveforms for fractional-slot concentrated-wound permanent magnet machines
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 are then obtained. A general expression for the generated back-EMF of FSCW PMSMs is then derived. The obtained analytical results are validated through finite-element analysis (FEA) and experimental tests on a prototype FSCW PMSM. A comparison between the generated voltages of various FSCW stator topologies is also performed.
