the fourth stage, in which the empty space inside the mold is filled with magnetic powder material;
the fifth stage, in which form a pole interconnected with the specified yoke, for which the magnetic powder material is subjected to pressure having a predetermined value, and heat; and
the sixth stage, in which the mold is removed, and then the winding is wound around the pole.
19. The method according to p. 18, in which these yoke plates are made by stamping from sheet steel while obtaining a given length and width thereof during the first stage.
20. The method according to p, in which the specified pole is formed by subjecting the magnetic powder material to pressure, followed by exposure at a temperature of the order of 300-500 ° C to obtain a monolithic structure during the fifth stage.
21. The method according to p, in which the insulator is attached to the point of contact between the pole and the winding or insulating material is pressed and attached in this place in order to wrap the winding on the pole.
