What does TENV mean on a motor?

Well – the answer is simply the motor is Totally Enclosed, and Non-Ventilated. Based on NEMA (National Electrical Manufacturers Association) definition, TENV states that the motor housing is fully enclosed and is not ventilated with a fan. The motor is being cooled unassisted (natural convection cooling).

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.

Is a TENV motor explosion proof?

Totally Enclosed, Nonvented (TENV) Motors do not have air openings. … Explosion-Proof (XPRF) Motors are completely enclosed to withstand an internal explosion of gas or vapor—the motor frame will not rupture or burst. Use these motors for safe operation in hazardous environments.

What is a TENV motor enclosure?

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.

What is the difference between TEFC and TENV Motors?

Totally Enclosed Non-Ventilated (TENV) motors are very similar to TEFC motors, except that they have no fan cooling system, relying on passive cooling with the surrounding air to keep the motor temperature under control. They have much the same strengths and weaknesses as TEFC enclosures.

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 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.

What is a DP motor enclosure?

Drip-Proof/Open Drip-Proof (DP/ODP)—Designed for use on horizontal motors, such as fire pump motors, these prevent drops of liquid or solid particles from entering ventilating openings in the enclosure at any angle from 0 to 15 degrees downward from the vertical.

Can a Tefc motor be used outdoors?

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.
