Cooling an electric motor means transmitting the losses that occur in the motor, turning them into heat and releasing them into the external environment. The aim is to keep the temperature of insulating materials below their limit values. Most standard Fabrika and Siemens electric motors are cooled using self-ventilation IC in accordance with DIN EN and are fitted with a synthetic two-way axial fan mounted on the non-drive end of the shaft. The first digit defines the coolant circulation method and the second digit the type of drive used to move or pump the coolant, as shown in Table When motors are mounted, a minimum gap must be maintained between the fan cover and the closest object to it, so that the air circulation is not compromised. As a rule of thumb, this minimum distance should be half the axle height. A minimum gap the same size as the fan cover is recommended for easier access for servicing purposes.

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 usually cost more than open motors, but offer increased protection against weather, dirt, and moisture. TEFC motors are constructed with a small fan on the rear shaft of the motor, covered by a housing. This fan forces air over the motor frame fins, and cools the motor. The enclosure is "Totally Enclosed". This means that the motor is dust tight, and has a moderate water seal as well. TEFC motors are not secure against high pressure water nor submersible. They are also not explosion proof without additional modifications.

Large Industrial Electric Motor Specialists. A totally enclosed fan cooled TEFC motor is a type of electric motor that uses a fan mounted on the rear side to blow air over the motor to provide cooling. TEFC motors are completely enclosed in a rugged housing which prevents dust, water, and other contaminants from entering the motor. The fan mounted on the rear of the motor pulls air in through openings and blows it over the motor windings to provide cooling. The enclosure keeps the internal components clean for optimal performance and prevents debris from interfering with operation. TEFC motors are available in single and three-phase power configurations.

This table summarizes the main differences between TEFC and ODP motors, including their enclosure design, environmental protection, cooling mechanisms, typical applications, and efficiency considerations. The choice between these motor types should be based on the specific needs of your application and the operating environment. No fans are needed in this type of motor. When electrical current flows through the windings of an electric motor it produces heat while operating. Due to this heat, the motor temperature rises, This rise in temperature could cause the motor to be burnt.

TEFC motors are constructed with a small fan on the rear shaft of the motor, covered by a housing. Compare to the ODP Open Drip Proof motor design, which has ventilation openings which are guarded to prevent falling water from entering the motor windings. The first digit defines the coolant circulation method and the second digit the type of drive used to move or pump the coolant, as shown in Table 1: Table 1: Cooling methods for electric motors in accordance with DIN IEC , Part 6 Minimum distance when mounting motors When motors are mounted, a minimum gap must be maintained between the fan cover and the closest object to it, so that the air circulation is not compromised.
