FIELD: metallurgy; copper and copper alloy half-finished products for electrical equipment.
SUBSTANCE: proposed section for electrical machine commutator is equilateral-trapezium shaped in cross-sectional area perpendicular to section length. Part of this section abutting against smaller base of trapezium is made of copper and that abutting against larger base of trapezium is made of copper ally. Part of section abutting against larger base of trapezium can be made of cadmium bronze.
EFFECT: enhance thermal stability and strength of commutator section.
