Yeah, I tried to cross reference it on their web site but the result wasn't the right motor. This must be a really old one.Tried, but couldn't find an exact match. Here is the contact info for questions per century's website:

It goes on an exhaust blower in a restaurant. I think they already tried a different motor but it wasn't adjustable and is running too fast.A 115 volt DC motor with a 115 volt field will be difficult to find, at best.
Depending on the application and the controller, it could be possible to substitute a 90 volt DC motor.
These are readily available in 56C frames from several manufacturers.

Just being nosy ... what feeds this motor ?
I can't read the RPM either.Not sure about the RPMs, can't read that photo because of reflection. But Baldor has this:
By the way, exhaust blower on a restaurant, as in cooking hood? I would NEVER use a DC motor for that! Brush maintenance would be a nightmare... Might be that it was put in to get variable speed back before VFDs were easy to use. Could be it's time to tell them that there is a better way to do this now and get rid of that relic.
To be honest, I'm not the one working on the motor. I was just trying to help a fellow electrician out. I'm not sure of the motor they got to replace it. I will try to find out about the available voltage.You realize of course that even on a DC motor, it is not the motor that allows for varying the speed, it is the drive. So if the DC drive is dead or was removed by someone earlier, that may explain why the new motor didn't work...
Changing to an AC drive of course also means changing to a 3 phase AC motor. There are dozens of good inexpensive AC drives that can be fed with single phase input and give you 3 phase output if all you have there is single phase. But at 2HP, it is going to have to be 230V single phase (or 3 phase) input, and that existing DC drive circuit might have been 120VAC feed. Do you have 230V available where your controller is?
