Resumen
The invention relates to the high speed deenergized system for the indirect excited synchronous machine (1) by (2) and rotation commutator bridge (8) it considers comprising the deenergized impedance (10) which this system is connected between the magnetic field winding wire (5) and rotation commutator bridge (8) of - synchronous machine (1); among the normal operation of - · synchronous machine (1) and the controller (9): connected in parallel with - deenergized impedance (10), the rotation commutator bridge (8) maintains the controller (9) with the closed state so that electricity is directly supplied to the magnetic field winding wire (5) of the synchronous machine (1); and the control circuit (11) of the controller (9) configured to open the controller (9) in the deenergized of · synchronous machine in order to serially maintain the deenergized impedance (10) with the magnetic field winding wire (5) and rotation commutator bridge (8).
