Document Type and Number:
Japanese Patent JP7430940
Kind Code:
B2
Abstract:
An electromagnetic coil where a conductive member is wound so as to surround an air core region includes an effective coil portion, a first coil end portion, and a second coil end portion. The effective coil portion is formed of a coil-use conductive wire formed by bundling a plurality of conductive base members, the first coil end portion is formed of a first end member that is made of a solid conductive material, and the second coil end portion is formed of a second end member made of a solid conductive material. In the air core region of “one magnetic material” to which an electric current of a first phase is supplied, the effective coil portion of “the other electromagnetic coil” to which an electric current of a second phase is supplied is fitted.
