How do I limit the start output of a 300 amp Starter/Generator to 200
How do I limit the start output of a 300 amp Starter/Generator to 200
(OP)
I want to limit the start output torque on a 300 amp generator to 200 amp, but I want the 300 amp generator to still be able to run as a 300amp gen. Are there some torque equations that I can use to create some parameters? Please help.

That is to say the motor needs to be driving some load to bother trying to develop torque. No load, no torque (other than internal friction in the motor), very low current draw.
As torque demanded by the load goes up, the current draw goes up. If the torque demand exceeds the torque that can be generated by the motor the shaft stops turning, and the motor burns up.
So, the way to limit the current drawn by a motor is to limit the load.

The subject of the original post stated "starter/generator", which I assumed to be an electro-mechanical device that functions as a starter for an internal combustion engine that is not running, and then subesquently becomes a generator converting mechanical power from that same engine into electricity after it is running, such devices being known to exist.
Regardless, motors and generators are fundamentally the same machine.

For a given power demand, Torque and RPM can be changed in inverse proportion to each other. Unfortunately, the torque required to turn the engine over is not the variable under your control. It still sounds like you have a mis-matched starter/generator, and you should use instead the starter/generators that are recommended by the engine manufacturer. To add electrical power durning operation, you can always add another generator to provide supplementary power to the main bus.
