Abstract:
1. An electromagnetic device comprising a plurality of coils, wherein each coil includes: a winding of a conductor, wherein at least a part of the conductor is a conductor stack so that an eddy current generated by a leakage flux linked to the conductor is divided; an insulating member disposed only on an outer circumferential surface of the conductor; and a core on which the conductor stack is wound, wherein: the outer insulating member is disposed between the conductor stack and the core; the coil is inserted and fixed in a slot provided in the core; the coil further includes a connecting member, which connects the conductor constructional elements together at an end of the conductor stack exposed from the slot to outside of the core and the end of the conductor stack is electrically connected with another conductor; the connecting member has a wiring portion provided in a base material composed of an insulating material; and the conductor stack is positioned and fixed on the base material and the end is electrically connected with the wiring portion and electrically connected with the another conductor through the wiring portion.
