Abstract As the wide applications of fractional-slot concentrated winding machine and high speed high power density permanent magnet synchronous machine (PMSM), the rotor loss has obtained more and more attentions. The impact of the stator magnetomotive force (MMF) harmonics is the biggest among many influence factors. After analyzing the stator MMF when it supplied by converter, a novel rotor loss influence factor ξ_k_,_v is proposed based on the Steinmetz separated iron loss model considering different magnetic paths of different harmonics. The bigger ξ_k_,_v, the more rotor loss is, and vice versa. Using the proposed rotor loss influence factor ξ_k_,_v, the rotor losses of two typical pole-slot combination machines with 8-pole 9-slot and 8-pole 48-slot respectively are analyzed. The finite element method (FEM) is then adopted to calculate the rotor losses of the two structures, and verifies the proposed analysis method.
