What is drip proof enclosure?

What is drip proof enclosure?

Open Drip Proof (ODP) This type of enclosure allows air to flow through the motor, so particulates are easily introduced. Bearings, rotors, and windings are open to contaminants that can cause a myriad of issues. These enclosures are resistant to liquids entering the machine from a 0-15o angle.

What does Opsb enclosure mean?

Open Slotted Band
Showing 1-2 of 2 answers. 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 are 4 common 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 Tefc enclosure?

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 is a Tewac?

Acronym. Definition. TEWAC. Totally Enclosed Water to Air Cooled (power generation; type of gas turbine generator)

What is FLP enclosure?

An enclosure for electrical apparatus that will withstand, without injury, any explosion of the prescribed flammable gas that may occur within it under practical conditions of operation within the rating of the apparatus (and recognized overloads, if any, associated therewith), and will prevent the transmission of …

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 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 motor enclosure?

PetroWiki. An enclosure protects a motor from contaminants in the environment in which it is operating. In addition, the type of enclosure affects the cooling of the motor. Enclosures are categorized as either open or totally enclosed, and there are different types of enclosures within each category.

What is the difference between TEFC and TENV motors?

Can a Tefc motor be explosion proof?

An external fan blows outside air over the frame of the motor to cool it. TEFC motors are not secure against high pressure water nor submersible. They are also not explosion proof without additional modifications.
