Ok, they say the reason for the overload is for short circuit protection.
If you lock the rotor of a fire pump, and supply it with LRA, how long (time) does the motor have to last?
In a funny kind of way, it almost seems like a high rotor resistance would be advantageous. With an impeller designed to provide the desired P-V curve with the somewhat increased slip.
