Abstract

End winding conductors are attached to bracing rings which are connected to a plurality of support brackets positioned around the outside of the conductors. The support brackets are attached to a ring-shaped member which has its radial movement restrained by a plurality of blocks which are positioned around the outside of the ring-shaped member. The blocks are adjustably attached to another ring which is fixed to the stator iron core. Springs are positioned between the ring-shaped member and the stator iron core to provide an axial load on the support brackets. Conductor movement due to thermal changes is prevented in the radial direction but permitted in the axial direction due to the axial movement of the ring-shaped member with respect to the blocks.
