Hey Peeps!
Hope you all doing good.
i'm currently designing a pcb in Altium designer for 2 motors which will consume a current of approximately 5amp for a very short interval of time like 500ms or 1s max, how much should i keep the minimum track width??

You're unlikely to find a precise analytical answer since there are many variables at play. I would design for the maximum steady state current you expect and then make it a little bigger if you think you need to. Large coppper pours are preferable for high current carrying capability.
