Document Type and Number:
WIPO Patent Application WO/2023/090424
Kind Code:
A1
Abstract:
This rotary electric machine comprises a stator, a rotor, and a casing that houses the stator and the rotor. A, which is the ｛111｝<211> orientation intensity of a base steel sheet of a non-oriented electrical steel sheet included in the stator, is less than 15, B, which is the ｛111｝<211> orientation intensity of a base steel sheet of a non-oriented electrical steel sheet included in the rotor, is 2-30, and A and B satisfy a relationship of B/A>1.0. C, which is the ｛411｝<011> orientation intensity of the base steel sheet of the non-oriented electrical steel sheet included in the stator, is 2-50, D, which is the ｛411｝<011> orientation intensity of the base steel sheet of the non-oriented electrical steel sheet included in the rotor, is 1-40, and C and D satisfy a relationship of C/D>1.0.
