摘要： PURPOSE:To prevent the application of stress to a root section in a connecting terminal by forming an interpole connecting section for a field coil in constitution in which the connecting terminal can be moved on thermal expansion. CONSTITUTION:A field coil 3 is shaped by winding flat type copper wires to a multilayer shape in an edgewise winding manner, and inter-wire insulators 4 are executed among each winding. Connecting terminals 5 for connections to the next poles are each fitted to an uppermost-layer winding section and a lowermost layer winding section. In interpole connection, the connecting terminals 5 for adjacent coils are connected alternately, and mounted to a support fitting 6 by using recessed type support fittings 11. The size of a groove for the recessed type support fitting 11 is represented by connecting terminal width added with a thermal expansion value after insulation. Accordingly, the application of forced stress to root sections (a) in the connecting terminals 5 is prevented.

摘要： PURPOSE:To readily perform assembling and repairing works by forming a conductor support in U shape. CONSTITUTION:A connecting conductor supporting device 1 is formed in U shape. Thus, even at reparing work time of the state that connecting conductors 2 are all assembled by brazing the device 1 can be assembled without disassembling the conductors 2.

摘要： PURPOSE:To facilitate wiring and connection work, by alternately arranging winding units different dislocating direction of strands one after another in a unipolar monophasic groove. CONSTITUTION:A three-phase stator winding is formed by connecting the space of winding units with an interpole connecting line which units are composed of multiple hexagonal coils 2 having multiple steps of strands a-f and arranged and formed one after another in a unipolar monophasic groove of stator core grooves 1. With this winding the abovementioned winding units consist of one that dislocated a strand (f) of lower step at the bottom coil lead wire section 5 of a coil 2 to the upper step and connected and formed respectively to the strands f-a at upper coil lead wire section 6 of the adjacent coil 2 and of the other that dislocated the strand (f) to a lower step in the same way and connected and formed. These winding units different in dislocating direction are alternately arranged one after another. Thus, in case the number of unipolar monophasic grooves is less than that of the steps of the strand, the dislocation can easily by performed.

摘要： PURPOSE:To prevent the breakage of binds, by separating the bind for a rotor coil from the bind for an end duct. CONSTITUTION:An insulating material 5 for a coil and a bind 6 for the same, which are wound around the rotor coil 2 from the end 9 side of the same, are separated from the insulating material 8 for an end duct and the bind 7 for the same at the end of the end duct 4. The part of the rotor coil, which is within the range of the end duct 4, is provided with a structure wherein a step is provided between the rotor coil 2 and the end coil 4 to open a gap so that the insulating material 8 for the end duct and the bind 7 are not in contact with the rotor coil 2. As a result, a force will never be transmitted even when the end duct 4 and the rotor coil 2 are elongated by separate frequencies of vibration and centrifugal forces, therefore, both of the insulating materials 5, 8 and both of the binds 6, 7 will never be broken.

摘要： PURPOSE:To absorb displacement between an upper coil and a bottom coil by forming tapered surfaces on the bottom coil, the upper coil and a connecting board while using the connecting board thicker than the thickness of the bottom coil and the upper coil. CONSTITUTION:Tapered surfaces 10B are shaped in the width direction of an upper coil 3 and a bottom coil 2, and tapered surfaces 10B are also formed to the connecting board 4c side. The connecting board is made thicker than the thickness of the coils by several mm. Accordingly, the displacement of connection between the upper coil and the bottom coil can be absorbed.

摘要： PURPOSE:To reduce a potential difference between strands by adding a rolling to a connection between poles together with the rolling of a stator winding end. CONSTITUTION:A bottom coil 2 is connected through an adjacent connection 6, and the upper lead 3 of an upper coil 1 is connected through a connecting wire 8 between upper lead poles with the coil of the next pole. The coil 2 is connected with the coil 1 through the connection 6, and the bottom coil lead 4 is connected through a connecting wire 9 between bottom lead poles with the next pole. The wire 8 is rolled in one stage from the upper side to the lower side. Thus, a potential difference between strands can be reduced to decrease an eddy current and an eddy current loss.
