Baldor motors

[volvoman]

So I have a few new ones up at work that I could get on the cheap side I think. 

15 hp at 1700 rpm
20 hp at 1700 rpm

most of them are 230-460, I have only seen few used and 2 in AC trucks and 8hp in small car.  What is your guys opions on even using these motors.
Thanks for any info you can give.

Nothing wrong with Baldor some say they are the best for the buck.  If they are inverter rated and price is right and they are right size for the load then grab em.

Would that be listed on the side of the motor, if they are inverter rated or not?  I think I could pull the numbers off the side and look them up but don't know how easy the look up would be.

I believe it will be on the nameplate often next to manufacturer name.

Well finally got around to checking on the motors. I was a little late as they had a pallet of motors that they got rid of for $500.  The last two they have are 20 hp. AC

There is a EM2334T also the premium efficacy.   I am wondering what controller I would use?   Most of the controllers with ac motors come in a packages.   If I am making this more difficult for my self let me know as I am still trying to find my way.   I am also going to a EV Portland meeting in two weeks to a least find some people that can give me an idea of what I need to do.   Thanks for any info

Looked at EM2334T.  Class F insulation is good BUT inverter duty is hard on "regular motors"  they do not have the insulation to handle the high voltage spikes.  I do not see inverter rated - would tend to steer clear of it.  Could work if you were very careful. 

20 HP will get you down the road OK, especially with VERY light vehicle ie 2,000 or so.  Will be limited if climbing steep hills or you want to accelerate quick.  NOT the choice if you want to win at drag races.

There is nothing wrong with Baldor motors they seem to be very reliable - some say best for the dollar.

Take a look at Baldor # IDM4115T
Is inverter rated
"Meets NEMA MG 1, Part 31"  -- this is spec for inverter ratings.
Probably a better motor especially since 50 HP.  The list price may be adjusted downward - depends on which Seattle rep you buy from.

I think you should also take a look at Azure - they have the former Solectria setups.  Good for comparison shopping, especially if you can make 20 HP work theirs are a little larger.  Contact Beth Silverman there for assistance.  She will get you answers and send you the manuals.  Very helpful.
I rejected them because of their dealer in California (no factory direct dang it) and I can get better customer support for VFD from Allen Bradley here in Seatle.  Azure now has a new dealer Canadian EV but at my last check he had not gained much experience with them yet.

Hmm I think I see another topic for the VFD and motor class I am teaching at No Seattle Comm College on Oct 18 and 25.
You can check the class out at the South Seattle Comm Coll Continuing Education website.
As of last week 10 of 15 allowed are signed up.  Cost $75

Let me know when your employer wants to get rid of more.  Kind of sounds like Boeing.

That was my concern not having enough hp also. I am going to do a truck set up because of the range I need for work and few hills.   I don't think that it prob is a good idea going this way with this motor.  I don't want to be limited to small oops or mistakes costing $ down the road.  Since this is going to be my first conversion I think that I am going to play it safe  for now and go with main stream motors and controllers.  Maybe by next year I can get going on something.  Thanks for help if you have any other things that come to mind let me know.  I live down here near Portland so Seattle is a bit out of the way.  I would consider a class like this if it was down here. 
Thanks

If you do the legwork to set up a class in Portland I will come and teach it.  Let me finish the Oct class first so I have a better idea of what people want and need.

One thing you can do with a VFD is drive multiple motors - you can control two 20 HP with a 40 HP VFD or bettery yet 2 20 HP VFD and motors - on 4 WD one for front axle and one for rear tied direct to driveshafts (ideally the differential but would take reinforcing).

Am also thinking of a class to teach how to do all the considerations determine your needs and wants do all the calculations for converting vehicle to electric.  Thoughts - feedback??

Going DC may be just the way to go for now especially if you can get a Zilla controller.

Most of this is in paper work stage and I have to get it by the boss before I do anthing. LOL Its like working for the gov I have to come up with all these numbers.  As for the class I think I am not ready for something like that yet.  Let me know how your other class goes though.
