Note:
1. Saturated magnetic induction, Bs, is measured under 2000~2400 A/m applied magnetism for 1J34, 1J51, 1J52 and 1J403. 800 A/m for 1J65, 1J67 and 1J83.
2. Iron loss P1/400 and P1/300 represent iron loss when peak magnetic induction reaches 1T at 400 Hz and 300 Hz, respectively.
3. Bm in Square coefficient Br/Bm represents magnetic induction strength under 80 A/m applied magnetic strength.
