What is Tefc type motor?

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.

What are the different types of motor enclosures?

Ten Common Types of Motor Enclosures

• Open Drip Proof (ODP)
• Totally Enclosed Fan Cooled (TEFC)
• Totally Enclosed Air Over (TEAO)
• Totally Enclosed Non-Ventilated (TENV)
• Totally Enclosed Force Ventilated (TEFV)/ Totally Enclosed Blower Cooled (TEBC)
• Weather Protective 1 (WP1)
• Weather Protective 2 (WP2)

What is the difference between ODP and Tefc Motors?

An open drip proof or ODP motor is a type of motor that typically runs cooler and does not overheat. On the other hand, a totally enclosed fan cooled, or TEFC motor has a closed off chamber which requires the use of an external fan to blow air over it.

Which is the best definition of a TEFC motor?

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.

What is the application of electric traction motor?

A traction motor is an electric motor used for propulsion of a vehicle, such as an electric locomotive or electric roadway vehicle.

How are the fixed field windings in a traction motor?

The fixed field windings consist of tightly wound coils of wire fitted inside the motor case. The armature is another set of coils wound round a central shaft and is connected to the field windings through “brushes” which are spring-loaded contacts pressing against an extension of the armature called the commutator.

Where is the fan located on a TEFC motor?

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.
