Abstract

A brushless synchronous machine with a limiter for main field voltage and a method of limiting main field voltage in a brushless synchronous machine are described. The machine includes a regulator to use a field current to excite main field windings and generate the main field voltage. The machine also includes a limiter to limit the field current to maintain the main field voltage corresponding to the field current below a limit based on a transfer function.
