Claim 0:
1. A system for multi-mode synchronous electrical power generation, the system comprising:
a stator including:
main stator windings that have first, second, and third stator phase windings wye-configured for three-phase operation, each of the first, second, and third stator phase windings having a plurality of series-connected inductive coils, the pluralities of series-connected inductive coils of the first, second, and third stator windings distributed about the stator in a stator arrangement; and
a rotor that is rotatable within the stator, the rotor including:
a slip ring(s) via which an excitation power is applied to the rotor;
a rotor configuration engine having:
an excitation detector that detects whether the excitation power applied to the rotor is a DC excitation power or an AC excitation power;
a configuration switch(es); and
a configuration controller that sets the configuration switch(es) to a power-generation switch configuration in response to the excitation detector detecting a DC excitation power, and sets the configuration switch(es) to a grid-power switch configuration in response to the excitation detector detecting an AC excitation power; and

rotor windings that include first, second, and third rotor phase excitation windings, each having a plurality of series-connected inductive coils distributed about the rotor in a fashion that corresponds to the stator arrangement, wherein when the switches are in the grid-power switch configuration, the first, second, and third rotor phase excitation windings are wye-configured to create a revolving magnetic field, and when the switches are in the power-generation switch configuration, the first second and third rotor phase excitation windings are in series-parallel configuration, thereby creating a stationary magnetic rotor field.
