Here, the influence of stator slot and rotor pole combination on performance of flux reversal permanent magnet (FRPM) machine with consequent‐pole permanent magnet (CPM) structure is analysed. First, for 12‐slot FRPM machines, the torque capabilities of CPM and conventional surface‐mounted PM (SPM) structure having different rotor poles are compared. It shows that the torques of CPM machines are largely affected by the rotor pole number while the torques of SPM machines are similar. This is further explained by the equivalent pole‐pair number and corresponding saturation condition. The influence of stator slot number and PM width ratio on torque performance of the CPM‐FRPM machine is then investigated. Finally, detailed electromagnetic performance of the 12/14 SPM‐ and CPMFRPM machine is analysed and compared.
