AC Synchronous Motor Question
AC Synchronous Motor Question
(OP)
I have a 3755HP 6600V AC Synchronous Motor and I was wondering if it is ok to run this motor at a stator voltage of 4160V continuously?
Are there side effects of operating a synch motor at lower than rated stator voltage?
The excitation requirements for this machine is taken care of fully so that isn't a problem.
Any help is appreciated.
Joe

The motor at full load does not use the maximum available torque. If 40% of the original starting torque will still start the motor you have a good chance that it will be able to develop 3755HP x (4160V/6600V) = 2367 HP.
