Cogging torque in fractional pitch PMSM is minimized when manufacturing induced errors are also minimized. This paper investigates additional cogging torque harmonics resulting from misalignment of the rotor and stator caused by assembly and manufacturing tolerances in an axial flux, fractional pitch PMSM. A simulation method utilizing superposition of a single magnet / single slot interaction has been used previously to decouple manufacturing errors such as magnet placement and stator non… CONTINUE READING
