Title:
LAMINATED CORE AND ELECTRIC DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/095837
Kind Code:
A1
Abstract:
A laminated core (100) according to the present invention comprises a plurality of leg parts (210a-210c) which extend in a direction that is perpendicular to the lamination direction of electromagnetic steel sheets and a plurality of yoke parts (220a-220b) which extend in a direction that is orthogonal to the lamination direction of electromagnetic steel sheets and the extending direction of the leg parts (210a-210c); and at least some regions of the leg parts (210a-210c) and at least some regions of the yoke parts (220a-220b) are configured from a same electromagnetic steel sheet at a same position in the lamination direction of electromagnetic steel sheets. The electromagnetic steel sheets are arranged so that a first direction among the easy magnetization directions of the electromagnetic steel sheets extends along the extending direction of the leg parts (210a-210c), while a second direction among the easy magnetization directions of the electromagnetic steel sheets extends along the extending direction of the yoke parts (220a-220b).
