Analysis and Design of an Axial-Flux Coreless Permanent Magnet Synchronous Generator with Single Stators and Double Rotors

In this study, permanent magnet axial-flux coreless synchronous generator is designed as single stators and double rotors and its electromagnetic and structural characteristics are analyzed. Core is not been used in the stator of the machine intended to be designed. Aim of this study is to provide reduction of iron loss. Moreover, easiness in the production stage of the machine is provided. Three-dimensioned electromagnetic analysis of the designed machine has been done through finite element method and transient solutions are suggested based on this. Within this study, arrangements have been made depending on certain standards in order that permanent magnets and coils obtain direct alternating current. The designed new axial-flux generator move as permanent speed of 500 rpm and so maximum voltage of approximately 100 V per phase is obtained. Furthermore, this machine does not need a gear system due to its design structure.
