Where to find a good Class I Div 1 Group BCD motor that is unpurged?

Div 1 group B is your problem.
Do you need it to be Div 1, or can it be Div 2?

Get rid of the hydrogen...
...or get rid of the Div 1 (normally hazardous) area classification (i.e. move the device)...
...or replace with an air motor.
Otherwise you may be on a long hunt, especially if you need inverter duty.
If it's not inverter duty, I believe they can be found, but can't recall the last one we bought.

What horsepower?
If over 200 hp, what voltage?
I have not done electrical power in a very long time.
Perhaps small motors could apply reduced ratings with NFPA 496 purge applications. This could be no surprise with 2 hp. Each order of magnitude larger could thin some purge applications. Purging fractional hp motors could be practical.
