Got it, thanks.
The reason I ask is, I'm working on an ebike that had a cheap undersized controller installed such that if I drive it at full throttle long enough, the controller overheats and shuts off. My plan was to simply upgrade to a controller with a much higher amperage rating, removing that as a concern.
But it sounds like doing this could just burn out the motor? I think I can change the software of the controller to limit maximum power output, I'll have to do that I guess.
I would not have expected a controller capable of 60A to attempt to actually force 60A through a 48V, 1000W motor if the throttle was held down; I would have expected it to apply battery-level voltage to the motor (or do an internal step up/down to a constant 48V) and simply permit the motor to draw whatever amperage it pleased at that in-spec voltage.
