AVR12 – PERMANENT
MAGNET GENERATOR
The permanent magnet generator (PMG) option
upgrades the excitation system of the generator
from the standard self-excited system to a
separately-excited system. The PMG couples to
the non-drive end of the generator and provides
an independent source of excitation power that
ensures initial voltage build-up. The PMG improves
the voltage response of the generator during
transient load application, such as motor starting,
and provides a sustained short-circuit current for
the operation of protective devices. Isolation of
the excitation power ensures that regulation is
not affected by non-linear distorting loads.
