| |
Your choices are...
|
|
|
| |
Single-phase
|
|
Standard commercial and residential power is single-phase, meaning one sinusoidal or other alternating voltage pattern.
|
| |
Three-phase
|
|
Three-phase power contains three simultaneous sinusoidal or other alternating voltage patterns, typically 120° out of phase with each other. Higher power efficiency and smoothness of operation is possible with three-phase operation. Three-phase power is most typically used for industrial or high power motors.

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.

Special / Extreme Environments
|
|
|
| |
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.
