An open drip proof or ODP motor is a type of motor that typically runs cooler and does not overheat. … A benefit to having the motor totally enclosed is that it’s protected from the outside environment, including dust, airborne contaminants, and many weather disturbances such as wind-driven rain.
Can an open drip proof motor be used outside?
The use of open drip-proof motors outdoors or in wet areas is not ideal. In the event of a failure, an open drip-proof motor should be replaced with a motor more suitable for an outdoor or wet environment.
What does ODP mean for pumps?
Open Drip Proof (ODP) 2. Totally Enclosed Fan Cooled (TEFC) An ODP motor’s housing features stamped vent openings to create airflow around the windings, which in turn cools the motor. The vents are strategically placed around the pump to try to direct water or moisture from landing on the windings of the motor.
What is an Open type motor?
An open motor has ventilating openings which permit passage of external air over and around the motor windings. A totally enclosed motor is constructed to prevent the free exchange of air between the inside and outside of the frame. but not sufficiently enclosed to be termed air-tight.
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.
Is a Tefc motor waterproof?
The enclosure is “Totally Enclosed”. This means that the motor is dust tight, and has a moderate water seal as well. TEFC motors are not secure against high pressure water nor submersible. They are also not explosion proof without additional modifications.
What does open drip proof mean?
An open drip proof or ODP motor is a type of motor that typically runs cooler and does not overheat. Due to the fact that the chamber has open vents and air can flow directly over the windings, this open drip proof motor tends to be slightly more efficient because the windings are cooler.
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 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 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.
What does tE stand for on motor?
The motor time tE for increased safety motor is prime safety parameter. The higher value of time tE means insulating system of Ex e motor is able to withstand the locked condition for long time so motor will be more safe for long duration during in specified abnormal condition in hazardous area.
What is drip proof?
Open Drip Proof (ODP)
Allows air to circulate through the windings for cooling, but prevent drops of liquid from falling into motor within a 15 degree angle from vertical. Typically used for indoor applications in relatively clean, dry locations.
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 drip-proof enclosure?
Open Drip-Proof (ODP) Motors are equipped with open enclosures. These motors are suitable for indoor use and clean atmospheres. … 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 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 totally enclosed?
TEFC (totally enclosed, fan-cooled) motors are equipped with an external fan to circulate outside air to the motor. … Although air does not freely move between the inside and outside of the motor, construction is not air- or liquid-tight.
