This study presents design and performance analyses for a new line start axial flux permanent magnet synchronous motors (AF‐PMSMs). The innovative part of this study is that AF‐PMSM can start directly from the line and operate with high efficiency and power factor after synchronisation. Prototype manufacturing was carried out after completing the analytical and electromagnetic designs for the targeted motor. The synchronisation capacity, power capacity, power–speed characteristic, power‐efficiency relationship along with the total harmonic distortion and back‐emf waveform of the induced voltage have been examined for the prototype motor. Simulation studies have been verified experimentally. The results obtained were compared with an induction motor with the same power. It was observed as a result of the work carried out and a line start AF‐PMSM is obtained that is 4–10% more efficient in comparison with an induction motor having the same power.
