At 75% of the rated voltage, the motor should be able to run continuously for 2 minutes

At 75% of the rated voltage, the motor should be able to run continuously for 2 minutes. What considerations underlie this requirement? Is 2 minutes too long?

If the work done remains constant and the voltage decreases, the current roughly becomes 1.3 times the original value; I think this serves as a metric for evaluating the motor’s performance when it is under overload conditions and operating for a period of 2 minutes.

This is the manufacturing requirement for motor manufacturers, right? Is it 75 or 85?
