Abstract: The technical solution relates to the field of electromechanical engineering and can be used in the manufacture of windings for rotating electrical machines (electric motors and electric generators) with or without slots, or for linear electric motors. A coil for manufacturing a polyphase winding for an electrical machine is made in the shape of an isosceles trapezoid from a self-sintering conductor. The active elements of the coil are straight, and the overhangs of the coil are bent at a right angle to the active elements of the coil and are curved along an arc of a circle in the case of rotating electrical machines or are straight in the case of linear electric motors. The dimensions of the trapezoid are determined by the width of the active element of the coil, the width of a tooth of the core, the thickness of the coil and the acute angle of the trapezoid.
