Does anyone have experience with the amperage spike on start up with motors attached to a flywheel?
All the presses I have been involved in use 3 phase motor with a star/delta starter.
The flywheel presents a Huge load on start up.
An induction motor at switch on, is essentially a transformer with a shorted turn secondary, so it is very important to get it up to rated run mode ASAP. The flywheel presents a delay in this process, so personally I am not at all surprised with the results you are seeing.
