TEFC vs. TEAAC Motors
TEFC vs. TEAAC Motors
(OP)
HI all,
I have a 2,000 HP motor to be procured and designed to be operating outdoors exposed to summer and winter time conditions. Outdoor ambient can be as cold as -45 Deg C (Canada).
I initially specified TEFC as these are vertical motors and TEFC would offer more compactness against TEAAC.
However, my client is asking for a TEAAC cooling system. I disagree as first, the motors are vertical mounting. Second, all TEAAC motors I have seen in the past are all horizontal and are installed indoors.
I would like to seek technical opinion from experts in this forum. Thank you.

RE: TEFC vs. TEAAC Motors
This is a very large motor for type TEFC enclosure. I don't recall seeing a TEFC motor > 500hp. Once you get to that size you generally consider something else (ie WP1, WP2, TEAAC).
Why is your Client considering TEEC (say over a WP2)? ie Is this motor to be installed in a nasty environment. What synch-rpm are you looking for?
TEEAC motors are available in a vertical configuration (I have never seen one, but the Siemens website does have some info on these puppies.)
