ABSTRACT:
A rotary machine having a stator assembly constructed by joining brackets to a stator core by all-round laser welding without entailing the thermal deformation of those components. The omission of through-bolts for fastening together the stator core and the brackets and the resultant omission of through holes in the stator core for receiving the through-bolts reduces the outside dimensions of the laminations of the stator core. Superfluous spaces in the stator assembly are filled with a resin to prevent the condensation of moisture attributable to temperature variation within the rotating machine, to provide the rotating machine with a high rigidity, to suppress vibrations and to enhance heat transfer from the stator coils to the brackets.
