This paper deals with an influence of current phase angle on a stall torque of magnetic-geared motor. First, a relationship between the current phase angle and the stall torque of the magnetic-geared motor is indicated in experiment. Next, the experimental results are deeply investigated by comparing an SPM-type magnetic-geared motor with an IPM-type one by using three-dimensional finite element method (3D-FEM). As a result, in the case of the IPM-type, it is clear that the modulated magnetic flux of the inner rotor magnet includes the armature flux. Furthermore, the influence of the modulated magnet flux from the outer rotor magnets is also investigated.

In this study, FeCo magnetic wires with different widths were fabricated by photolithography and facing targets sputtering. Specifically, the domain configurations in the magnetic wires were studied. Flux closure domains with both 90° and 180° domain walls were found in magnetic wire with uniaxial transversal magnetic anisotropy. Furthermore, when the uniaxial transversal magnetic anisotropy was increased, a dramatic increase of 180° domain walls was found in the magnetic wire. These results suggest there are potential for applications for magnetic wires in stress-induced magnetic domain wall motion devices.
