The shunt generator will build up voltage only if field circuit resistance is less than critical field resistance.

The critical field resistance is the maximum field circuit resistance for a given speed with which the shunt generator would excite.

As the Concordiat expanded to the stars, and especially after the production of the first, crude FTL hyper shunt generator in 2221, the Bolos were both humanitys vanguard and its final line of defense.

A shunt generator is a type of direct current electric generator in which field winding and armature winding are connected in parallel, and in which the armature supplies both the load current and the field current.
