Abstract

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.
