My K45 has never shut down, though the whole motor section gets pretty dern hot when smashing pasta through the rollers....
The service manual states:

Under normal conditions, the mixer will not show any tendency to heat because of the built-in ventilating system in the motor. Under heavy loads with extended mixing time periods, the mixer head may heat up to the point of being uncomfortable to touch.

The schematic diagram does not show any heat sensor; then again, the ground wire is shown as "optional"....
