Document Type and Number:
WIPO Patent Application WO/2021/141029
Kind Code:
A1
Abstract:
The present invention prevents the generation of magnetic distortion sound without increasing iron loss. A reactor (6) comprises an outer peripheral core (20) and three core coils (31 to 34). Radially inner ends of the cores (101 to 104) of the core coils are spaced apart from each other with magnetically couplable gaps therebetween. The outer peripheral core (20) is formed by laminating a plurality of magnetic plates in a laminating direction. The reactor further comprises a pressurizing member (81) having a plurality of protrusions (82, 84) for locally pressurizing the outer peripheral core in the laminating direction.
