The conditions for the use of composite materials based on ASC100.29 iron powders with an oxide coating in electrical machine devices for stator manufacturing with improved performance characteristics are examined in the article. Conditions for increasing the stability of electric motor operation based on changes in the thickness of the oxide layer are determined. Three-dimensional models of magnetic circuits that make it possible to achieve a force of up to 4500 N with a torque of 3 to 8 Nm are used in the study; they make it possible to obtain a motor power of 100-200 W. In the research, experimental characteristics of dependences µ=F(h), H=F(h) and the specific loss power of on the thickness of oxide coating W yg =F(h) were obtained. Methods for measuring the dynamic characteristics of the stator magnetic circuit were determined.
