Hey Guys,

Newbie here...Needed some help with hooking up a 2004 SMM on Single Phase Power.

I have been trying to find relevant info for my machine but there is always some sort of variance.

I know i am close just missing something very simple.

Any help and/or pics would help. Note I have a Large Input Transformer at the bottom with 4 Voltage Range Inputs.

Thanks in advance!!

Do you have this document, look on page 9

Hey Jeff,

I was reading that and one part confuses me.

Page 5, Top of page #3. The Two Different Input Connections for Wire # 74.

I dont have a Small Input Transformer but a Big one at teh bottom with 4 different Ranges to connect to.

my input is 250 for connected to 244-260V with wires #74, 75, & 76


NOTE: The Red Wire in L2 is Not Live. That is my Neutral Wire but not hooked up to anything.

Also i was just reading somewhere and am more confused now!

"Personally, I would try and find a standard mini mill rather than the super mini mill. They are usually a little cheaper, more bullet proof, and can run on single phase."

Does this mean a Super Mini Mill CAN NOT run on Single Phase?

Thanks

I don't understand, the red wire is not hot, it should be. Black and red should be hot and white should be neutral.

it was just a wiring thing.. i can just swap the wires so Red is Hot and White is Neutral (swap else where just ignore colors). What i'm saying is that the Center Connection L2 has nothing connected to it.

Ok I changed the wiring to reflect correct colours.

What size spindle do you have that will tell you if you can run on single phase or not

I hope you have not connected the Neutral you should not have that at all in you cable Just 2 Hot and Ground

The first Photo is incorrect Red and Black or Black and Black are connected to the 2 outside switch Terminals only, the center Terminal is not connected for single Phase

[jeffrey001]

If your mill is supposed to run on single phase, you should not connect the white wire, Normally, 3 inputs are for 3 phases, 1 phase per wire, if you hook it up on single phase, only the red and black should be use, on L1 and L3.

Use this info at your own risk, I'm not an electrician.

Its was wired correctly, The Colors were just swapped. at all time the hot was only on outside and center was a dead line.


The Supply to the machine comes from a Single Phase supply The Neutral is not going to anything. it is a deadline.

Only outsides Hot, 125V & 125V.

Spindle is 15k rpm, 15HP. it is the Upgraded Option.

The Center is not connected to anything at the other end.

[jeffrey001]

If your spindle is 15HP, then it surely 3 phases, you'll need a phase converter to get 3 phases

I was checking the Electrical Requirements again.

SMM shows 3 Phase - 40A BUT there is NO * beside it stating that No Single Phase is Available.

On the Mini Mill it shows Triple & Single Phase Amperage.

I was told that running SMM on Single is possible but performance is reduced by 35%-50%

Looks like i may be SOL on this without Phase converter! There goes anther $5K!

The spindle is double the Kw of the mini mill, you should look at a Phase Perfect converter, they are more expensive but are your best choice for clean efficient 3ph power

Locally here there is

AMERICAN ROTARY
PHASE QUEST

These guys any good?

They recommend their 40hp model. But fo say can operate off 30HP unit also.

American say 98% efficiency.

And that is total Bs 98% try about 40% if that, the only company that could claim that is Phase Perfect, you will never get that with a RPC

Does Phase Perfect have a location in Toronto? Also if RPC are not that efficient then does that mean Phase Perfect is a Static Converter?

I'm pretty ignorant to these things so I'm trying to learn as quickly as possible. Lol. I have a machine sitting last 3 weeks that I can't use yet.

Thanks!

I called the Phase Perfrct Distributor here for Ontario. They told me a 20hp unit is good for the 15hp machine.

They sent me specs I have to review tonight.

Since you have one can you give me some feed back from your experience.

The cost is approx $7,600cad after tax. Double the price of a RPC.

Also, where are u located? Canada or states?

Thanks!

I did not say I had one, but I do have one and yes they cost around $7,500, for that size, yes they have no moving parts if that is what you mean, they do have 2 fans to keep them cool, but are not what is called a static converter, I'm in the USA

Incidentally many 3ph NFB's (Non-Fused Breakers) need to see current through all three phase connections, therefore it is common industrial practice to loop one of the hot (L1 or L2) back through from the outer to centre connection when using it for 1ph .
Also if using the Phase Perfect I would ensure that any non 3ph loads, i,e, single phase transformers etc, are fed off of the 2phases derived from L1, L2 and not the generated phase.
