Three 12-slot/10-pole closed slot permanent magnet machines having either all or alternate teeth wound winding and equal or unequal tooth width stator are analyzed and compared in terms of spike type voltage distortion. The difference between three machines, such as the rotor positions determining voltage distortion and the influence of current, is emphasized. Referring to the distorted voltage, the influence of such distortion on fluxweakening capabilities of three machines is compared as well. It is found that there is a larger voltage distortion for the machine with alternate teeth wound winding compared with the all teeth wound machine if they share the same machine dimensions. Besides, the unequal tooth width stator adopted for torque improvement purpose will further aggravate the voltage distortion.
