| 摘要 |
The present invention relates to a multiple alternating current generator comprising: a rotating shaft; a plurality of rotors coupled about the rotating shaft so as to be able to rotate together with the rotating shaft; a plurality of stators formed in cylindrical shapes so as to surround the rotors, a plurality of coil winding units being formed on the inner peripheral surfaces of the stators such that coils are wound, respectively, and the outer peripheral surfaces of the stators being coupled to a housing; a housing of a cylindrical shape comprising a plurality of stator coupling grooves, in which the plurality of stators can be arranged, and intermediate support unit grooves, on which a plurality of intermediate support units can be arranged, the housing comprising bearings provided towards both sides so as to support the rotating shaft; and intermediate support units, which are coupled to the intermediate support unit grooves, and which have bearings for supporting the rotating shaft between the plurality of rotors, wherein the generator has such a structure that semi-cylindrical upper and lower housings are coupled into a cylindrical shape, and the upper housing is separated by opening the same upwards, thereby facilitating assembly and maintenance. In addition, the present invention may have such a structure that the rotating shaft is configured as a single piece or comprises a plurality of separate pieces, which are connected and assembled, and the assembly structure is characterized in that the rotating shaft is inserted into both sides of a pipe-shaped rotating shaft connection member, and the connection member and the rotating shaft are fixed by a headless bolt. |
