Exitation voltage is the voltage required to establish the
working flux in the air gap.It is DC in nature and applied
across the field winding which is generally placed on the
rotor in the case of alternator.
With the application of exitation voltage, current strats
flowing through short circuited rotor windings,this current
is termed as exitation current.
Alternator works on the principle of magnetic locking
between stator and rotor fields.The exitation provide the
neccessary rotor field,without which alternator would not
convert mechanical energy into electrical energy.

We are preparing another project which involves Waste heat recovery from a 1 MW GE Engine. The Engine in particular gives out flue gas at 487Deg C with a flow rate of 5650 kg/hour and this can be cooled to 180 Deg C. This gives a thermal output of ~ 594 KW that is available for input to VAM via heat exchanger / boiler. Additionally 581 KW will be available from engine jacket water (temperature profile 80/ 80 Deg C and a flow rate of 50m3/hr) Our estimation is that 300 TR of cooling is possible with a suitable VAM machine(s). Please advise what is the most suitable arrangement with maximum TR and min Capital expenditure. plz reply me as early as possible
