Victor 888 ESC with NPC-T64 Motor: Understanding Surge Current and Stall Torque

Hi,

I have the NPC-T64 motor: http://www.robotmarketplace.com/products/NPC-T64.html

I am looking at getting the IFI VEX Pro Victor 888 speed controller: http://www.vexrobotics.com/217-2769.html

Looking at the NPC motor dyna test on the robotmarketplace link, it looks like it operates under 43A, but the stall torque is 110. Looking at the speed controller, the operating current is 60A, but it says the surge current (2 sec) is 150 A.

I'm not exactly sure what the surge current means. Does that mean that I can apply 150A to the speed controller for 2 seconds? Or maybe I'm completely off. Also, what happens if it is for longer than 2 seconds? Does it burn out the speed controller, or do they all have some kind of current limiting switch?

Thanks,
Jason
