Totally Enclosed
|
|
Totally enclosed motors have an enclosure that prevents free exchange of air between the inside and the outside of the enclosure. Common ratings are TEFC (fan-cooled) and TENV (non-ventilated); this is not an airtight rating. These motors are most frequently used in potentially contaminated environments.

Dust-proof
|
|
Dust-proof motors protect against dust infiltration with features such as total enclosure and labyrinth seals for shafts.
The IP (Ingress Protection) rating for dust-proof motors is IP6x.

Drip-proof
|
|
Drip-proof motors contain ventilation openings that are designed so that drops of liquid or solid particles falling from any angle within 15 degrees of vertical cannot enter the motor.
Motors with an IP rating of IPx1 through IPx9 are considered drip-proof.

Waterproof
|
|
There are several degrees of waterproofing applicable to motors and they are reflected in the IP rating for the motor:
IPx1: Protection against vertically falling drops of water (drip-proof).
IPx2: Protection against direct sprays of water up to 15 degrees from vertical.
IPx3: Protection against direct sprays of water up to 60 degrees from vertical.
IPx4: Protection against water sprayed from all directions.
IPx5: Protected against low pressure jets of water from all directions.
IPx6: Protected against high pressure jets of water from all directions.
IPx7: Protected against the effects of immersion up to 1 meter.
IPx8: Protected against long periods of immersion under pressure.

Your choices are...
|
|
|

Clean Room Use
|
|
Clean rooms are classified by particulate size and density in the ambient air. One such rating method classifies rooms according to number of particles larger than 0.5 micron in one cubic foot of air. There are various governmental, metric, and international standards. Motors rated for suitability in a clean room will identify the particular standard for which they are rated.
|
| |
Cryogenic Use
|
|
Motors with a cryogenic rating are constructed for extremely low ambient temperatures such as 20 K and below.
|
| |
Explosion-proof
|
|
Explosion-proof motors have totally enclosed housings that are constructed to withstand internal explosion of a specified gas, vapor, or dust. Should such an explosion occur, the enclosure would prevent the ignition or explosion of the gas or vapor surrounding the motor enclosure. Several explosion-proof ratings are governed by Underwriter's Laboratories (UL).
|
| |
Radiation-hardened
|
|
Radiation-hardened motors are constructed of materials designed to withstand high-energy gamma radiation. Ratings are expressed in units such as permissible RADs in total accumulated dose (TAD).
|
| |
Vacuum Use
|
|
Vacuum-rated motors incorporate features such as lubricant vapor pressure below rated ambient vacuum and construction techniques.
