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 does TENV mean on a 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 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 drip proof motor?
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.
Is a Tefc motor explosion proof?
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.
Can a TENV motor be used outdoors?
TENV motors are not considered airtight, therefore you would not use them in wet environments, but you could use them in slightly damp and definitely dirty environments. They are not suitable for hazardous or explosive environments.
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.
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 are the two types of motor enclosures?
The two general classifications of motor enclosures are open and totally enclosed. 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.
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.
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 does ODP stand for motor?
An often overlooked step to improve motor reliability is simply to upgrade open drip proof (ODP) motors.
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.
How do you tell if a motor is explosion proof?
An explosion proof motor is clearly marked with a nameplate that identifies its suitability for a given hazardous environment. Depending on the agency certifying the motor, the nameplate will clearly indicate the hazardous location Class, Division, and Group for which the motor is suited.
Can Tefc motors be used in hazardous locations?
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.
Are brushless motors explosion proof?
Available in 70-155mm frame sizes, EX motors feature an explosion-proof housing, making them suitable for use in explosive atmospheres.
