### Re: Maximum temperature of a step motor

Our step motor windings use Class B rated insulation wire. The Class B rating is 130°C (266°F). There is an approximately 30°C (86°F) temperature drop form the windings themselves to the motor case surface. Therefore, the maximum case temperature should be 100°c (212°F).

To determine the maximum ambient temperature of our stepping motors, we know that the maximum temperature rise for a stepping motor at rated voltage and two phases ON is 80°C (176°F) from experimentation. If you subtract the maximum temperature rise of the motor 80°C (144°F) from the maximum winding termperature of 130°C (266°F), the maximum ambient temperature for a stepping motor would be 130°C - 80°C = 50°C (122°F)

I think this post would be most helpful in explaining how to program and execute motion with our stored data products such as the AR66MCD-PS25-3 package model which you are using.
