Just got back state side and got my variable speed motor in to upgrade my KMG grinder.

I just got done running a 220V line to where my grinder is and have a question about wiring the motor. The motor is a 2 horse 220v, and list on the data plate 230/460V. It's pre wired for high voltage,(wires in motor are twisted together) but should it be wired for high or low? Input power will be 220V to the controller, not 460.

I tried calling Beaumont, but it was after 1900 last night and no answer, I'll try again today, but it's a Saturday.

Thanks

Low voltage
 
That's what I thought, but a buddy of mine has the same thing and swears his was wired for high voltage and has been running it for a while. What would happen if I ran it in the wrong voltage set up? Lack of power or short motor life, or both?

Thanks
 
If you have a 120 and 240 option on the motor, then you would wire high volt.

If you have a 240/460 then you would wire low volt.
 
Thanks, that's what I was thinking, but after my buddy told me he asked Beaumont about it and was told to leave it high voltage I got concerned. Maybe he remembers wrong or something. Has happened to me enough in the past if I don't write something down, and even then forget where I wrote it.

Just don't want to screw up a very expensive addition to the shop.

Thanks,

I've read there instructions, they don't state wether to set the motor up for high or low voltage, just if your running on 220 or 110 to set it for that.

If you read the manual, or data sheets, or the sticker on the bottom of your VFD, it will specify 220v 3θ phase output

Your motor must be wired to accept 220v 3 phase.

The high voltage / low voltage depends on the data plates on your motor.
 
Thanks, now my head is exploding.

I'm pretty sure your rite, like 99.9% sure, and it's got to be wired for the low voltage, but in the interest of not burning something up I'll wait till Monday and call Beaumont just to make sure. In the mean time I've got enough other stuff to do to keep me busy.

Excellent idea . . .To easy to confuse terminology. . .I thought it was clearer in the instructions. Upon closer examination I realize the instructions left a lot of "maybes" & "uuuuuuuuuums" . . . So please post results of your call to Beaumont . . . I too have a 2hp variable speed Beaumont still in the box. Had it for over 2 weeks now. I have spoke to Rob a couple of times with questions prior to purchase & he comes across a little fast with answers, so make sure you understand him totally because if you smoke the VFD you will be dealing with the VFD maker is my understanding from reading on this forum.

No worries, just itching to get it hooked up. Of course I'm still mowing the jungle I call a yard after being gone for a month, among other things that don't get done while I'm at work.

I'll post what he says,

Not that bad, but one of the few places I've worked where they have actual grass huts.
 
I hope you got the motor wired and working.

Your motor should be wired to be the same as the OUTPUT VOLTAGE on your drive. Some/most drives have jumpers to select between two output voltages (i.e. 230V vs. 460V), similar to how your motor can be wired to either 230V or 460V. The important thing is that the output voltage of the drive match the "wired voltage" of the motor.

There are probably efficiency or performance reasons to choose a higher motor voltage, if it is an option . . . but I can't state those with any authority.

Got it working, talked with Rob today and wired it to the low voltage side. Was pretty sure that was the way, but didn't want to risk the motor.

Don't know about wiring, me and electricity don't get along and I'm pretty clueless when it comes to it.

Thanks
