Abstract

S. Maney & Son Ltd. This paper investigates the operating characteristics of hybrid-flux-modulated motor with amorphous magnetic material core using 3D time-stepping finite element method. In the proposed hybrid-flux-modulated motor, the radial-iron segments and axial-iron segments in the air-gap are used to modulate the magnetic field, the concentrated stator windings are built to reduce the end length, therefore to reduce copper losses, the stator core and the modulated segments are built with the amorphous magnetic material to reduce the core losses and therefore to enhance the efficiency of the motor. The flux distribution, electromotive force waveforms, cogging torque, output torque, core losses and efficiency of the proposed hybridflux-modulated motor have been investigated. All studies show that the efficiency of the proposed hybrid-flux-modulated motor can be improved by utilising amorphous magnetic material and the motor is potential to apply in variable speed driving applications.
