Totally Enclosed, Fan-Cooled (TEFC) Motors have an external fan which circulates outside air to the motor. Totally Enclosed, Nonvented (TENV) Motors do not have air openings. While air does not freely move between the inside and outside, the motor’s construction is not air- or liquid-tight.
What does TEAO mean on a motor?
Totally Enclosed Air Over/Airtight (TEAO)
This motor has a dust-tight frame or enclosure. It is typically installed in the airstream, and the air movement generated by the fan passes over the motor to provide cooling. TEAO motors would be used in areas with direct drive where the motor is in the airstream.
What is a TENV motor?
TOTALLY-ENCLOSED, NON-VENTILATED (TENV) — A totally-enclosed motor of sufficient size and mass to permit the necessary heat dissipation to eliminate the need for external cooling. TOTALLY-ENCLOSED FAN-COOLED (TEFC) — Basically a TENV motor which has an external fan to blow cooling air over the motor.
Can a TENV motor be used outdoors?
TENV motors are not considered airtight, therefore you would not use them in wet environments, but you could use them in slightly damp and definitely dirty environments. They are not suitable for hazardous or explosive environments.
What type of motor is a Tefc?
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 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.
Are Tefc motors rated for outdoor use?
A totally enclosed, fan-cooled (TEFC) motor is much more adaptable to outdoor locations and high moisture areas. With a bit of care, you can expect this type of motor to work well and have a long life.
What is an ODP motor?
The ODP (open drip proof) is one of the most common types of enclosures. The enclosure is open and vented at the back end of the motor and allows air to circulate in and around the motor windings carrying off heat.
What is motor insulation class F?
The F refers to the insulation class for the windings, while the B refers to an 80°C rise (the maximum temperature rise for Class B is 80°C). This type of notation is becoming more widespread because many motors use Class F insulation, and there is a reason for that.
What is XPFC?

Can a Tefc motor get wet?
Totally Enclosed Fan Cooled (TEFC) motors are more adaptable to outdoor and high moisture areas. Their enclosed design does not have openings that allow free exchange of air between the inside and outside of the motor, but even so, they are not airtight or watertight.
Which type of motor enclosure is best?
When considering which motor enclosure is best, look at the type of cooling the motor requires and most importantly the environment that the motor will be operating in. Open Drip Proof – ODP motors are almost always the least expensive of all motors which often times makes them the preference of equipment OEM’s.
What are the two types of motor enclosures?
The Most Common Types Of Electric Motor Enclosures
- The most common types of enclosures are:
- Open Drip Proof (ODP)
- Weather Protected (WP1 / WP2)
- Totally Enclosed Fan Cooled (TEFC)
- Totally Enclosed Non-Ventilated (TENV)
- Totally Enclosed Air Over (TEAO)
- Totally Enclosed Forced Ventilated (TEFV)
- XP (Explosion Proof)
What is a PE motor?
They mean the same electrical 0v potential. The purpose of PE is to protect against electric shock and fire due to leakage current. While motor grounding used to take place with one of the four bolts or screws, dedicated screw terminals are offered now for easier implementation.
Can you use an ODP motor outdoors?
To put it bluntly, installing an ODP motor outside, or inside in a moderately dirty environment is a substantial waste of money. When they are not running, insects and critters seem to use these motors for nests.
What type of motor is used in exhaust fan?
Exhaust fan motors usually have single phase induction motors, like that of ceiling fans. They are designed according to the functions they need to serve. Most small exhaust fans use this standard motor, that is, the single phase motor.
