TEFC Motors for HVAC Applications
TEFC Motors for HVAC Applications
(OP)
Greetings
I came across the below statement in a HVAC pump handbook regarding TEFC motors. Can anyone explain please?
"Totally enclosed, fan-cooled motors are available for applications where the motor is wetted periodically. It should not be used for
routine motor applications in this industry."
Thank you

TEFC are much better motors than open motors. another benefit is dirty air can't get in the windings and coat them (and burn them out) like in open motors.

Unless you can guarantee complete cleanliness, I wouldn't use open motors.
there are other things that tell if a motor is good or not.... OEM can undersize windings in a TEFC and use cheap bearings. but in general go with the better motor.

A fire pump also is housed in a clean and fire separated room.
So that is not a good comparison. Dirt on open motors is an issue over long running time since the windings overheat and the insulation degrades. If your fire pump experiences similar exercise you probably should call the fire department to extinguish your building :)
