This paper presents trade studies and performance comparison of the design space for a fractional slot concentrated winding (FSCW) surface permanent magnet (SPM) machine architecture using non-rare earth manganese bismuth (MnBi) magnet and 6.5% Silicon Steel laminate. Trade studies were performed with following machine parameters, namely, stator outer diameter, airgap, current density, stator slot and rotor pole combination. This paper also attempts to compare target performance metrics with different soft (namely, M19, HIPERCO Ⓡ and high Silicon steel) and hard magnetic materials (namely, NdFeB48, MnBi and Ferrite). Each of these designs was obtained using an external optimizer (Infolytica-OptiNet) meeting required torque while minimizing active material weight. This paper also verifies that select design can deliver flux weakening characteristics over the speed range.
