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 does Tefc mean on a motor?

TOTALLY-ENCLOSED FAN-COOLED (TEFC) — Basically a TENV motor which has an external fan to blow cooling air over the motor. The additional cooling eliminates the necessity of a more costly oversized TENV motor.

What does ODP mean on a motor?

An often overlooked step to improve motor reliability is simply to upgrade open drip proof (ODP) motors.

Can you use an ODP motor outdoors?

Open Drip Proof (ODP) motors are usually much cheaper than TEFC motors, but are highly susceptible to whatever contaminants are present in the ambient environment. … To put it bluntly, installing an ODP motor outside, or inside in a moderately dirty environment is a substantial waste of money.

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 Tefc and TENV motors?

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 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.

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.

Are TEFC motors rated for Class 1 Div 2?

Class I, Division 2 Motors

TEFC (Totally Enclosed, Fan Cooled) motors and ODP (Open Drip -proof) motors can be used in Division 2 locations provided they do not have ignition sources such as arc-producing brushes or switching mechanisms.

What are 4 common types of motor enclosures?

What is Opsb motor enclosure?

ODP = Open Drop Proof | OPSB = Open Slotted Band, technically it is the same and Baldor is the one who uses the OPSB terminology, ODP is open at the front and back of the motor, OPSB is open at the front back and on the body or band of the motor, again this is Baldor only.

What is EC motor technology?

An electronically commutated (EC) motor is designed to run on an alternating current (AC) power supply, but it in fact bears a closer resemblance to a direct current (DC) motor. It is essentially a permanent magnet, brushless DC motor that incorporates on-board electronics.

What is a TEAO 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 WPI enclosure?

Weather Protected Type 1 (WPI) – As you might expect, the Weather Protected Type enclosures are for outdoor use. Their purpose is to prevent debris, dust, rain, and rodents from entering the motor.
