Abstract

An electric power transmission device according to one embodiment of the invention includes a magnetic core, a first winding, a first rotary member, a second winding, and one or more rectifiers. The magnetic core has a ring shape including a through hole through which a shaft extends. The magnetic core includes therein a cavity along a circumferential direction about an axis of rotation of the shaft, and has an opening provided along the circumferential direction in a surface in contact with the through hole. The opening couples the through hole and the cavity to each other. The first winding is provided in the cavity and wound along the circumferential direction. The first rotary member is provided at a location corresponding to the opening in an axial direction of the axis of rotation, and is rotationally movable in the circumferential direction, inside the cavity, with a rotation of the shaft. The second winding is provided on the first rotary member and wound along the circumferential direction. The one or more rectifiers are provided in contact with the shaft and are coupled to the second winding.
