Non-oriented electrical steel for driving motor of electric vehicle and manufacturing method of non-oriented electrical steel

The invention discloses a non-oriented electrical steel for a driving motor of an electric vehicle, which contains Fe and inevitable impurities, and also contains the following chemical elements in percentage by mass: less than or equal to 0.003% of C, 3.0-4.5% of Si, 0.15-2.5% of Al, 0.15-2.5% of Mn, less than or equal to 0.015% of P, less than or equal to 0.015% of S and the balance of Fe. The magnetic induction intensity B50M of the non-oriented electrical steel for the driving motor of the electric vehicle is larger than or equal to 1.60 T, B50M = (B50L + B50C + 2B50X)/4, and B50L is the magnetic induction intensity in the rolling direction during magnetization under the magnetic field of 5000 A/m; b50C is the magnetic induction intensity perpendicular to the rolling direction during magnetization under the magnetic field of 5000A/m; and B50X is the minimum value of magnetic induction intensity at different angles from the rolling direction when magnetization is carried out in a magnetic field of 5000 A/m
