In this paper, a five-phase hybrid-excitation flux-switching (HEFS) machine with “E”- core stator cell is proposed and analyzed. The topology and operation principle are investigated. Moreover, the armature winding connection method is analyzed and the analytical sizing equations are derived to determine the main design parameter of HEFS machine. The electromagnetic performance, including the conventional...
Eddy current brakes having advantages such as contactless operation offer an alternative to conventional friction-based brakes. The flux source in an eddy current brake can be produced by permanent magnets or electrically excited windings. The former eliminates the need for an external supply, whereas the latter provides good control capability for the device. Herein, in order to take the advantages...
A sizing comparison among Axial Flux Permanent Magnet (AFPM) motors is presented. The adopted procedure, implementing traditional sizing equations, is simple and quick; it is aimed to reduce the free design parameters, in a basic parametric analysis, to obtain an improved design. The procedure, already applied to the design of wind energy AFPM Synchronous Generators, is used here to size an AFPM Synchronous...
This paper presents summarized electromagnetic and thermal design of interior permanent magnet motor for a low-floor tram TMK 2200. Motor geometry is optimized for maximum torque density using differential evolution algorithm. The influences of winding configuration on power losses and thermal transients in the motor during one driving cycle of the tram have been analyzed. The results indicate that...
In this paper, an optimal design of a high-speed switched reluctance motor (SRM) with lower torque ripple using the Taguchi method for household appliances has been presented. To enhance the efficiency and reduce the manufacture processes of the proposed high-speed double-salient SRM, the soft magnetic composite (SMC) material is adopted. Moreover, to decrease noise and vibration of the double-salient...
Design of multi-turns concentric saddle windings are required for flux concentrated permanent magnet transverse flux machine, FCPM-TFM in a sector wise configuration. In the segmented construction of FCPM-TFM, saddle coils or concentric type of windings are used to replace the ring coils, which are normally utilised in the conventional layered-phase structures for generating fields' perpendicular...
