Answer / jeff b.

A pmg is a Permanent Magnet Generator. It is a small
generator that is typically on the same shaft as the main
generator rotor. Since it utilizes permanent magnets, no
external source is required to excite the PMG to produce an
output. It thus becomes a source (a small generator) whose
output is used to provide power to the automatic voltage
regulator and excitation to the main generator field.
