FIELD: metallurgy.
SUBSTANCE: invention relates to the metallurgy, namely to a sheet of non-textured electrical steel used as a material for the manufacture of electric vehicle drive motors. The sheet has the following chemical composition, wt. %: 0<C≤0.003, Si 1.6 3.4, Mn 0.1-1.2, S≤0.003, Al 0.1-3.0, Sn 0.005-0.2, Ca 0.0005-0.01, O≤0.003, N≤0.003, at least one element of Nb, V or Ti, the rest is Fe and unavoidable impurities. The steel composition satisfies the following conditions: 33 ×O/16+S/32≤12 ×Ca/40, Nb/93+V/51+Ti/48≤C/12+N/14 and Nb+V+Ti≤0.01%.
EFFECT: present invention enables to produce a sheet that has the required magnetic properties.
