Hey everyone i have a motor lined up that is 230v not 230/460v just wondering if this would work ok for vfd setup. Also will this motor be a good choice. Any help would be appreciated
Thanks

1,5kW, should be fine as far as Power is concerned.
You can drive every AC motor with a vfd.
230 means that you'll have to connect it up as star. Otherwise it'll get 400V and die.
 
Oh if you're in america it may be possible to drive it via delta connection
 
Since that is a 3 ph motor you should be good. Look in the peckerhead to see how many wires are there - bet it's only 3 since it's a single voltage motor. If so, you're in business and don't have to worry about how to connect. Just connect any one of the 3 wires to terminal 1, next to 2, next to terminal 3. If motor runs backward when VFD is in forward, just reverse one of the pairs - say take wire from terminal 3 and put in terminal 2, with the terminal 2 wire to terminal 3.

It there are 6 or 9 or 12 wires, all bets are off.
 
Yes, it will work fine with a VFD having 220-240VAC output. Most sold in the USA state 220 VAC, but line voltage actually varies from place to place. Just connect the VFD output as normal.

Not EVERY AC motor. Just 3 phase.

I notice this is a "Baldor Smart Motor", so it's possible it may already be set up with an inverter. Have you seen the motor in person jrrock?

No, not just 3-phase, also regular AC with one phase and neutral. I wouldn't necessarily use it for a grinder or something similar but you could do it if you wanted to.

Could be, what's the line on the data plate that says "drive"

It was sold packaged with a drive ?
 
Thanks for the info guys, no i have not seen it in person it is being sold by a industrial equipment and supply outlet that carries all kinds of motors but this seemed the closest match for a grinder and the price is good. I am about 8 hours from there location so its a no go on checking it in person and they don't seem like they will check the wiring. I live in Canada and have a 240VAC outlet in my shop, i was just unsure as it is a single voltage motor.
 
My understanding of Baldor ”Smart Motor” system, It has inverter guts enclosed in a giant peckerhead attached on the motor housing. Its keypad controller locates remotely wherever desired.

None the less, if this is just the smartmotor absent its inverter guts, it should be able to connect to any VFD just as any other 3Ø motor.

If it includes the Smartmotor guts and you want to get a keypad & use that, be sure it will work with the power you can supply it.
Also,
Be sure its frame type is useful for your application.
 
Reading more about the Baldor "Smart Motor" it seems the VFD is mounted direct to motor. "IF" so, then it will require a 3 ph power feed, not the usual single phase of the normal VFD we use. I'd love to see a photo of the total motor. The examples I found show a housing mounted on top of motor with a plug for a remote keypad to do the programming.
 
Lieblad must have been writing while I was writing - looks like we doubled with our post.
 
These are the only pics on the site.

They also have this motor for the same price but i was hoping to get the higher rpm.

I really appreciate all the help so far.

So you think the the vfd would need to supply 3 phase? maybe this motor is to risky if i cant see it in person?
 
Unless that motor is almost free, I'd pass on it. It really looks like the VFD is enclosed inside the big box on top of motor. That means you'd need to have a source of 3 phase power available, AND you'll also need the remote handheld programmer for the VFD to do any changing with the program.

Just as a matter of interest, what is the price range of that motor? Anything over $100 shipped I wouldn't be interested at all.

Any thoughts on the other Baldor?
 
Ooops, I just saw your post above showing the 2nd motor. That one looks usable, but do note the 145TC frame rather than the normal 56C frame. Of course, it depends on what you plan to use the motor for, and what mounting you'll use. You did mention the price was the same? A 2 hp 3 ph motor at 3450 rpm from Automation is around $160 shipped for a brand new motor.

You will need a VFD to power your 3 ph motor - Are you planning a NEMA 4X enclosure for dust protection? OR a NEMA 1 open enclosure? I've been using NEMA 1 enclosures for the last few years with good luck by putting a filter over the air intakes to prevent any dust (especially metal dust) from getting inside and causing electronics to go bad.

jrrock, what part of the world are you located in? Perhaps someone from the forum could help if they're anywhere close to you.

Ok, single phase AC can be technically set up to run variable speed, but it's usually much more cost prohibitive than a 3 phase set up, and not ideal for something like a grinder (or anything requiring relatively consistent torque across the whole speed range).
