Title:
NONORIENTED SILICON STEEL SHEET FOR IRON CORE OF MOTOR AND PRODUCTION METHOD THEREFOR
Document Type and Number:
Japanese Patent JP2002226952
Kind Code:
A
Abstract:
To provide a nonoriented silicon steel sheet which has low core loss in a high frequency-high magnetic flux density region, has small residual magnetic flux density, and is suitable for a switched reluctance motor.
The component of the steel are controlled to a composition containing, by mass, ≤0.0050% C and 0.1 to 7.0% Si. Further, its residual magnetic flux density Br1.8 when magnetized to 1.8 T is controlled to ≤1.0 T, or its core loss W15/800(L+C) to ≤150 W/kg.
