Abstract

Diverse topology of three-phase and single-phase Field Excitation Flux Switching Machines (FEFSMs) that have been developed recently have several advantages such as variable flux capability and the single piece structure of rotor suitable for high-speed applications. However, overlap windings between armature and FEC cause the fundamental principles of the develop machine with salient pole rotor created the problems of high end coil, increases size of motor as well as high copper losses. A new topology of single phase segmented rotor FEFSM with 12S-6P configuration is presented with the advantages of non-overlap armature and FEC windings, less weight, low copper loss and high efficiency. The design, operating principles, characteristics of torque, speed and power of this new topology is investigated by JMAG-Designer via a 2D Finite Element Analysis (2D-FEA), while Solidwork software is used in the fabrication process. The initial design enables to obtain maximum torque and power of 16.6Nm and 10.74kW, respectively suitable for High Density Air Conditioner.
