Title: Iron core for reactor
Inventor: YAMAMOTO ISOO
IPC: H01F37/00
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To miniaturize an iron core for a reactor and reduce its weight. SOLUTION: Yoke cores 4, 5 are constructed by laminating directional silicon steel plates. The laminated directional silicon steel plates are bent at the both ends along the rolling direction of the directional silicon steel plates.
