Electric motor worst case current is locked-rotor (stall).
But the failure mode is overtemperature in the insulation,
most commonly. You get to temperature by time and
power (I^2*R), and starting from hot you have less
margin to the critical temperature so less time allowed
at the problem-making condition.
