Analysis of rotor disc thickness in coreless stator axial flux permanent magnet synchronous machine

This paper presents the analysis of rotor disc thickness in coreless stator axial flux permanent magnet synchronous machine (AFPMSM) with double external rotor and internal stator. An important advantage of these types of machines is that rotors can be implemented by using massive ordinary construction steel. Due to the high possibility of large weight of AFPMSMs there is a tendency to implement as lightweight design as possible. In this work, the influence of rotor disk thickness on AFPMSM characteristics is investigated.
