Rotating electrical machine, stator core and rotor core set, method for manufacturing rotating electrical machine, method for manufacturing non-oriented electrical steel sheet, method for manufacturing rotor and stator of rotating electrical machine, and non-oriented electrical steel sheet set

A method for manufacturing a non-oriented electrical steel sheet for a rotor core and a non-oriented electrical steel sheet for a stator core of a rotating electrical machine,

• wherein a {111}<211> orientation intensity (A) of the stator core is in a range of 2 to 30, a {111}<211> orientation intensity (B) of the rotor core is in a range of 1 to 15, and both the orientation intensities satisfy a relationship of an expression (1) A>B, wherein when a non-oriented electrical steel sheet in which a chemical composition includes, by mass %, C:
• 0.0100% or less, Si:
• 2.6% or more and 4.5% or less, Mn:
• 0.10% or more and 3.00% or less, P:
• 0.15% or less, S:
• 0.0030% or less, N:
• 0.0040% or less, Al:
• 0.10% or more and 2.00% or less, one or more selected from Sn and Sb:
• 0% to 0.200%, Cr:
• 0% to 5.0%, Ni:
• 0% to 5.0%, Cu:
• 0% to 5.0%, Ca:
• 0% to 0.010%, Mg:
• 0% to 0.0100%, a rare earth element (REM):
• 0% to 0.010%, Ti:
• 0.0030% or less, B:
• 0.0000% to 0.0050%, O:
• 0.0000% to 0.0200%, and a remainder of Fe and impurities is manufactured by processes that include steelmaking, hot rolling, hot-rolled sheet annealing, pickling, cold rolling, and finish annealing, two types of annealing temperatures for the hot-rolled sheet annealing are set, and a hot-rolled sheet annealing temperature of the non-oriented electrical steel sheet for the rotor core is set to a temperature in a range of 860° C. to 1000° C., which is higher than a hot-rolled sheet annealing temperature of the non-oriented electrical steel sheet for the stator core.
