Need help with the motor choice
(OP)
Hi everyone!
I need a good motor for industrial fan but I’m quite puzzled, cause the variety of models is very wide.
I stooped my choice at three brands WEG, Baldor and Leesson. So possibly I could consult with you guys here:
Single HP
1725 or 1800 RPM
Three Phase
TEFC preferred
56C frame size
Which technical specifications to consider else?
Any experience with these motors?

Standard voltages are 230/460 Volts.
If you are in a rural area subject to fairly wide voltage swings, or if you are on a 120:208 Volt supply, look for a motor rated for 200-230/460 Volts or 208-230/460 Volts.

three-phase power is available,
Have you heard something about the WEG? their price suits me the best
I know that it is manufactured in Brazil and it seems like it deals better with humidity
RE: Need help with the motor choice
There is a reason why their price looks favourable.

I have not purchased the parts via the Internet, it will be the first my try. I used to buy it from my local dealer, so let’s hope I won’t get something used.

Also, if this is going to be run from an inverter drive, I'm suspicious of Weg's claims about all of their motors being "inverter duty". That term has no official definition, anyone can claim anything. I look at all of the actual construction details, not just the magnet wire onsulation and when I have looked at Weg, their details are sketchy at best, which leads me to believe they purposely leave them out.

Siemens for example owns former MEZ Motors in the Czech Republic. Motor distributors buy exactly the same motors from the MEZ factory but then the motors are not labelled with Siemens' name although the motors are 100 % identical.
