Axial flux Permanent magnet (AFPM) machines are popular due to their higher power density and reduced size. In recent years development of electrical drives and other direct drive applications, axial flux machines are gaining more attention. AFPM machines have a problem of cogging torque that needs to be tackled carefully. Cogging torque produces electrical noise and torque ripples. Power of an AFPM machine is directly proportional to its diameter, which makes cogging torque a sensitive design parameter. Cogging torque is proportional to the square flux and change in reluctance, with respect to its position to the stator. This paper paper explores various cogging torque reduction techniques.
