In this paper an axial flux PM machine with field control capability for variable speed application is presented. To achieve such as control, surface mounted PM rotor-pole configuration is shaped so that, a lowreluctance path is included. In thisway, controlling the armature reaction based on vector control allows us to command the airgap flux in a wide range. Magnetizing and demagnetizing effect can be reached with a low stator current requirement. In order to handle the rotor reluctance, an iron and PM sections are include. 3D-FEA is carried out to confirm the viability of the proposed topology. Also a procedure to estimate the d-q parameters for the topology is presented [ABSTRACT FROM AUTHOR]
