Title:
ROTARY ELECTRIC MACHINE CORE
Document Type and Number:
Japanese Patent JP2019088163
Kind Code:
A
Abstract:
To provide a rotary electric machine core having reduced iron loss and sufficient strength.SOLUTION: A stator core 100 includes: electromagnetic steel sheet laminates 104A, 104B, 104C; and nanocrystalline alloys 105, 106 filling cavities formed inside the electromagnetic steel sheet laminates 104A, 104B, 104C. Since surroundings of the nanocrystal alloys 105, 106 are surrounded by the electromagnetic steel sheet, strength of the stator core 100 can be ensured. By using nanocrystal alloys 105, 106 for the stator core 100, iron loss can be reduced.SELECTED DRAWING: Figure 1
