Explanations
Permissible operating range
The permissible operating range is limited by thermal, mechanical, and electromagnetic
boundaries. The data in this documentation is valid for self-cooled motors up to an ambient
temperature of 40 °C.
The temperature rise of the motor is caused by the losses generated in the motor (current-
dependent losses, no-load losses, friction losses).
To maintain the temperature limits, the S1-permissible torque – starting from static torque M
0
– decreases as the speed increases.
