Zusammenfassung:A support system is provided for a dynamoelectric machine 200 having a stator 206 and stator bars 204, 205 connected to a connection ring assembly 230. The support system includes at least one stator bar support bracket 210 and one or more support rings 212 connected to the stator bars. A connection ring support bracket 230 supports the connection ring assembly 230. A mount assembly comprising the connection ring support bracket 240, resilient element 230, and fastenings 245 permits axial movement of the stator bars, the stator bar support bracket, the support rings, and the connection ring assembly due to thermal expansion experienced during operation of the dynamoelectric machine. The expansion may be accommodated for by springs 240 or low friction sliding contact pads 442 (e.g. PTFE material) The connection rings may be assembled outside the machine and a handling arrangement for the installation of the connection rings into the machine is also disclosed (fig 5-8 not shown). Lifting support blocks are located between banks of rings and a lifting beam attaches to lifting provisions provided on the support blocks.
