Dear Alex,

Steppers run hot. What limits the maximum temperature at which you can run a motor is the temperature rating of the insulation.

For example....

NEMA class A insulation is good up to 105 degrees centigrade. That means that if ambient is 40 degrees C, the motor coil can cope with a temperature rise of 65 degrees C.

Here is some good stuff on the matter..
