In practice, however, since there will be a loss in transferring theenergy from electrical energy into energy in the form of compressedair and back again into mechanical energy, this loss, whatever itmay be, must be drawn from the storage tanks, and the requisiteamount of air from these tanks supplied to rotor cylinder R C iu during acceleration, in which case this total power would lie repre-sented for any given instant by ;i point above line B C. 3. Full Speed: When the rotor has reached full synchronousspeed by the pre\ious operation, this speed can be maintained bymoving the controller to another position which will throttle theoutlet pipe of cylinder S C until the reaction due to the pressurebehir.d the piston iquals the full capacitv of the electric motor.
