Open Drip-Proof (ODP) Motors are equipped with open enclosures. These motors are suitable for indoor use and clean atmospheres. Ventilator openings are designed to prevent liquids and solids from entering the machine from an angle of 0 to 15°.
What is ODP on a 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.
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 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 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.
Does an ODP motor have a fan?
An open drip proof or ODP motor is a type of motor that typically runs cooler and does not overheat. … Although the ODP motor doesn’t require external cooling (our idler motors have an internal fan) the open concept can allow airborne contaminants and dust to enter the chamber.
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 does Opsb enclosure mean?
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.
Is a totally enclosed motor explosion proof?
Totally Enclosed, Fan-Cooled (TEFC) Motors have an external fan which circulates outside air to the motor. … 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 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 the primary purpose of the motor enclosure?
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 most common type of enclosure used in residential wiring?
NEMA 1 ELECTRICAL ENCLOSURES
Despite their limited protection, NEMA 1 enclosures are commonly used in a variety of industries to house indoor electrical equipment, such as variable-frequency drives installed in standard indoor locations.
Which type of enclosures used in motors?
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 2 (WP2)
What is a WPI motor 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.
How do I choose an electrical enclosure?
To properly select an enclosure for an application, it is necessary to know what environmental hazards the enclosure must protect against, and what NEMA rating or IP code provides the desired level of protection. Some accessories, like drip shields, can improve the enclosure performance in falling water environments.
