Flux modulated machine (FMM) comprises three parts: a conventional stator with armature winding, a rotor with permanent magnet, and iron flux modulation pole. Thanks to the inherent magnetic gearing effect, FMMs have been gaining more attention for their features of high torque density. So far, the windings of existing FMMs are fed with pure sinusoidal current. In this paper, to further improve the...
Flux modulated machines (FMMs) are well known for their features of high torque density. In this paper, the DC currents are innovatively injected into the armature coils which are arranged in a specific way in FMMs, and the electromagnetic performance are analyzed by the finite element analysis (FEA). The results show that the electromagnetic torque contains not only the pre-existing PM torque, but...
