Motor heating conditions
The rated motor specifications are continuous allowable values at a surrounding air temperature of 40 °C when the motor is
installed with a steel flange. When the motor is mounted on a small surface, the motor temperature may rise considerably
because of the limited heat radiating abilities of the surface. Make sure you use a suitable flange according to Siemens
recommended flange sizes.
Note
The actual temperature ris
e depends on how the flange (motor mounting section) is fixed on the installation surface, what
material is used for the motor mounting section, and motor speed. Always check the actual motor temperature.
