A totally enclosed, fan-cooled (TEFC) electric motor is a type of industrial electric motor with an enclosure that does not permit outside air to freely circulate through the interior of the motor. An external fan blows outside air over the frame of the motor to cool it. This motor is arguably the most commonly used motor in ordinary industrial environments. TEFC enclosed motors offer increased protection against weather, dirt, and moisture. Cast iron frame, IE1 - Standard efficiency. Foot & large flange mounted design.
