Abstract

In this paper, the authors present a cogging torque evaluation by a new two-dimensional (2-D) analytical solution of the no-load magnetic field with the slotting effect in multi-pole surface mounted permanent-magnet (PM) motors (SMPMM). The cogging torque waveforms have been compared with the finite element analysis (FEA). The analytical results are in very good agreement with those obtained by the FEA, considering amplitude and waveform.
