Abstract

This paper presents the performance analysis of a new two stators and central rotor Axial Flux Permanent magnet machine with tooth coil winding. The novel rotor topology proposed has a non-ferromagnetic structure that reduces the leakage flux and also reduces the total machine weight. Ferromagnetic layers adding in both side of magnets allow to reduce the slotting effect, eddy current losses and consequently improve the machine efficiency. Furthermore, optimization of this iron lamination let to increases the saliency ratio, add a reluctance torque component and help to protect the magnet of short circuit current. Some adverse effects are also analyzed such as the increased Cogging torque. 2-D finite element analysis was carried out to study the machine performance considering manufacturing issues. The results were verified in a 100 kW machine prototype.
