Title:
ELECTROMAGNETIC COIL
Document Type and Number:
Japanese Patent JP2022041690
Kind Code:
A
Abstract:
To provide an electromagnetic coil which can reduce eddy current, miniaturize a coil end, and dissolve processing process problems of disconnection and wire diameter distortion due to forming of a conducting wire for a coil.SOLUTION: An electromagnetic coil 1 constituted by winding a conductive member so as to surround an air core area 101 has a trapezoidal shape, and comprises: an effective coil part 102; a first coil end part 103; and a second coil end part 104. An upper base part 121 having the trapezoidal shape is arranged on a first surface, and a lower base part 122 is arranged on a second surface different from the first surface. The effective coil part 102 is constituted of a conducting wire 110 for the coil constituted by bundling a plurality of conductive base materials, the first coil end part 103 is constituted of a first end member 130 constituted of an individual conductive material, and the second coil end part 104 is constituted of a second end member 140 constituted of an individual conductive material.SELECTED DRAWING: Figure 2
