Rotating Electric Machine, Set Of Iron Core Of Stator And Iron Core Of Rotor, Method For Manufacturing Rotating Electric Machine, Method For Manufacturing Non Oriented Electrical Steel Sheet For Stator And Non Oriented Electrical Steel Sheet For Rotor, Method For Manufacturing Stator And Rotor, And Set Of Non Oriented Electrical Steel Sheets

Abstract: This rotating electric machine includes a stator, a rotor, and a housing that houses the stator and rotor, wherein at least one of the following conditions 1 and 2 is satisfied. Condition 1. The thermal conductivity A of a non-oriented electrical steel sheet used in an iron core of the stator is 12 to 35 W/(m·K), the thermal conductivity B of the non-oriented electrical steel sheet used in an iron core of the rotor is 10 to 33 W/(m·K), and the thermal conductivities of the two satisfy the following formula (1): A > B. Condition 2. The thermal diffusivity A1 of the non-oriented electrical steel sheet used in the iron core of the stator is 3.0×10-6 to 9.0×10-6 m2/sW/(m·K), the thermal diffusivity B1 of the non-oriented electrical steel sheet used in the iron core of the rotor is 2.5×10-6 to 8.5×10-6 m2/sW/(m·K), and the thermal diffusivities of the two satisfy the following formula (3): A1 > B1.
