Ok guys I need some help and quick. I found a guy with a couple of 3 HP Baldor Motors for sale and from what I can tell the price he is offering is pretty good. I am currently trying to work out a deal for a couple of them.

The motors are new in the box and still wrapped in plastic wrap. These are the specs that I have been able to gain.

3 Hp
3450 RPMs
115/230
Amps 30/15
HZ 60
1PH
Class B
Code K
TENV

Questions

1. The gentleman selling the motors thinks they are AC and told me that I could run the motor on my 110 shop set up but that I should go with 220 to optimize the motor. Is this true can I really run the motor on 110 and if so will it put a huge load on the basement fuses.

2. I understand what the AC means to the variable speed aplication I will be wanting from my Belt Grinder. I researched the posts here about variable speed. If I did want to go variable speed will the 3hp motor be able to handle a load even if it is ac due to the 3hp.

3. What is a good price for these motors I checked the baldor site and found the cheapest one was about $450.00. The sellers initial deal for one motor is under this price.

4. Totally enclosed No Ventilation ok I know this means that I can grind without the fear of the motor sucking in metal dust and one day exploding but will it burn up if pushed hard. NO VENTILATION that sounds scary. Can I possibly ventilate the motor my self if I buy it, and still keep it sealed.

5. The model number on the motor is 86696-300 and I will be calling baldor for info on the motor but if anyone recognizes the model number as a bad one let me know.

6. No they are not stolen I checked he is getting them from a friend who has a motor business and they had ordered them for a job and the job got cancelled.

Finally I saw one of the motors that the gentleman has in his woodworking shop and it worked great.

If all checks out and someone gives me some good news I will be buying 2 of the 3 he has. I told him one of my buddies would probably want the third. I will let you all know the price I am able to get the deal for. So who wants one. Anyone interested I will post the 3 motor price deal price here soon and I will work out shipping with the buyer.

I would really like to help out one of the struggling wanna bees like me here that wants to one day wake up walk out to the shop and have the buffer grab a hold of an extension cord and spin it into his family jewels like a pro.

I want to be able to show my scars at the knife show too.

Jim, the volt/amp ratings 115volts/30amp, 230volts/15amp, I would run it on 230 if possible, if not make sure your wiring in your basement can handle a 30 amp load safely. If your looking for variable speed you'll want to go with a DC motor and controller. Don,t mess with trying to vent the motor, it will possibly ruin it, leave it as is. I don,t know what you have in mind for this motor, but a 3hp 3450 buffer is pretty unforgiving, be carefull!! Oh Yeah the scar thing aint all its cracked up to be, they are painfull and cut into your knifemaking time, right now my wife Audra is on the mend (again) she was grinding a piece of sheephorn that rolled out of her grip, ground a chunk out of the backside of her thumb, nasty looking mess!!it will heal, it just takes time....

I am no motor expert, but, I believe what I will tell you here is true:
-If the motor is single phase, it can be set up for 110 or 220V by switching a couple of wires inside the motor. Baldor motors generally have the wiring diagram printed right on a label that is on the cover plate.
For a 3 HP motor, I'd try and run it on 220V, because the current draw will be larger at startup, and you will probably be turning it off and on frequently.
-As far as I know, variable speed requires a DC motor. These won't work if they're AC.
-Regarding cooling-if the motor says TEFC, it's a go. I don't know the implications of the TENV designation.
-you can call Dan Johnson at Stephen Bader and ask him what he thinks of the price
518-753-4457.

Generally, deals like this come with some sort of tradeoff. 3HP is more than you probably need, and you might be able to get a 2 HP motor that suits your needs better for the same money.

a motor that big will pull down your 110 circuits if the wire isnt big enough or your breakers arent BIGGER than the rating. put two 110s together and you have 220. better. you would wreck the motor trying to run it variable speed...pulley system would be best. I have a motor that big on my compressor and it makes all the lights go dim when it fires up, and its on it own 220 line. why do you need such a big motor..2 hp is plenty for a grinder....most guys use 1 or 1.5. I have a 2 hp on my bader and i cant stop it grinding. Whatever you do, dont burn down your house trying to save a few hundred dollars....for 1/3 more than the $450 for one from the manufacturer you can get a variable speed with controller that will last forever....if I were you, I would go for that route...in the end you will be MUCH more satisfied.

DT;the Baldor motors are good ones. A 3hp is a real handful if your not real careful.
DT; the baldor motors are good ones. A 3hp could be a real handful if you are not very very careful. Tenv could be a problem as these motors are designed to run in a airflow. They could overheat otherwise. You did not list your motors frame size, this is kinda important as it tells the motors shaft size,bolt mounting pattern,and whether it has a c-face;for mounting to say a Bader grinder. Go with the high voltage hook-up, the internal switches and parts in your motor will last much longer. For variable speed you really need a dc motor to make a go of it. The going price of a 3hp 3450 RPM 1ph.115/230 TEFC motor is $285 U.S. plus shipping. Thats kinda what I do to feed the family so I can keep making knives. I would be glad to answer any questions I can that might help you.


 
As usual guys your a worth of information.

I am just trying to get a good deal on a motor so I can finish making my first 2x72 grinder. I guess this deal was indeed to good to be true.

I have all the material to make a grinder kinda like the Pro-cut II offered in Kovals catalog. Thats is what I really need a good motor for.

I have a buffer and no that is not what I wanted the motor for. Makes me shiver thinking of trying to use one that powerful. The story I paraphrased about the buffer grabbing a cord was told to me by a buddy of mine who is a full time knifemaker. I plan on learning from everyone of those stories I hear.

Anyhow the price for the motors is $220. for one and $187.50 if I bought two.

I have pretty much decided I will search for a 1hp to 1.5 hp motor and forget these 3hp headaches.

Thanks again guys


Jim

With this motor you are going to need a motor starter to keep from burning it up on the start. I just set up one of these on my hammer, got the starter from Grainger. I can look up the # for it if you buy it. Paid $75 for mine,it needed new capacitors. Baldor is one of the best.
