Hi,

Can anyone please advise on the weight of the generator rotor in a GE frame 6B type machine? also does anyone know about the requirement for a 'stub shaft' to bolt onto the rotor to allow high speed balancing, because there is only a bearing at the exciter end and the gearbox bearing gets left behind when the rotor is unbolted from the gearbox?

any advice would be much appreciate.
Thanks

 

Can you tell us the manufacturer and model No. of the generator please?

 

Hi,

it's a GE Frame 6B design manufactured by European Gas Turbines in 1997. The generator nameplate states type T190-240 Wye 3 Phase, 53.412 MVA nominal power. It was built to generate at 13.8kV 60Hz but we changed the gearbox and excitation settings to operate at 11.5kV 50Hz.

Thanks,
David
