Totally Enclosed Fan Cooled (TEFC) motor
enclosures do not allow free air flow
through
the motor. TEFC enclosed motors are sealed
against leaks and dripping liquids.
The
opposite end of the motor drive shaft has a
cooling fan mounted on it. A specially
designed
shroud helps direct the fan driven outside air
over the exterior of the motor
for cooling.
This is not considered a submersible motor.
