Heavy 10 First Step - Power

[GSPV]

While I don't have hands on machining experience, I have a buttload of experience around other heavy machinery. And, well. I have enough common sense to understand safety first. Short sleeves, no loose clothes, nothing around my neck or hands, eye protection, stay out of the way of the chuck, etc.

Guys,

My SBH10 was run on 3 phase power.

I’m assuming that this means that it has a three phase motor. How would I verify this?

If it is 3 phase, what are my options for running it on home electric service?

Replace the motor? Some kind of converter? Can a VFD alone do this?

Dusty, helpful man that he is, pointed me to this converter http://vi.raptor.ebaydesc.com/ws/eB...tegory=185148&pm=1&ds=0&t=1533943346000&ver=0

Warning, this may lead to a “benefits of a VFD” followup.

Thanks in advance,

Motor tag will tell you if it's 3 phase. Vfd will run your 3ph motor with single phase input to vfd.

I have no hands on machining experience. Going to a trade school is the opposite of practical for me. I’m going to learn hands on, with manuals and YouTube.

Need to get this puppy running first. First step to that is power. First step to power seems like it is verifying what the current motor is. Then, advance from there.

I’ll report back tonight.

Be careful a lathe can hurt you, don't run it with loose clothing on.

That brings up the benefit of a VFD and how to use it.

I was over on practical machinist. The concensus seemed to be to use the pulleys for most speed control and the VFD for only fine speed adjustment.

Is that true in our context? Where I’ll mostly be doing 416R?

Not really mine has a vfd,all I do is run motor rpm up& down except for back gear

OK. Here we are.

So, looks like I have to dig deeper to see if it is 220 or 440 voltage. Definitely 3-phase. Have to check on the current, too.

Standard 3ph motor ,look at motor wiring to see what it's wired on.

Yep. Another task for another night.

Motor can be wired (at the motor for 208 or 22 or 440....just follow the diagram on the motor plate....

A rotary converter can be loud....but a static converter normally only gives 2/3 (in HP) .....you must have 220vt single phase to feed the converter....

 

[GSPV]

What would be the pros and cons of replacing the motor with one that will run on single phase?

I use a rotary, the American Rotary ADX.

https://www.americanrotary.com/products/view/adx-smart-converter

It's nice and smooth and provides full power. My bridgeport was running on a static phase converter for years until I installed an ADX-10 for my 5hp lathe and now I run the bridgport off of it too. It now has full power. I'm much happier.

The rotary can be built with any 3 phase motor (available locally cheap) as your idler motor you can buy one for American Rotary.

I ended up with the electronics for an ADX-5 brand new never used. If you are interested I'll give you a very good deal on it compared to what American Rotary would charge.

I put the phase converter over in a corner of the shop and I hardly notice it. I wired a remote start stop switch at the lathe and the mill.

My heavy 10 has a single phase 110V motor that was installed by the previous owner. Plugs into the wall and runs fine. If you decide to go that route, I can take a photo of the information plate if you need the info.

 

[Dusty Stevens]

I want that motor if you change it out to a single phase

 

[ridgeway]

Don't convert to 1 phase. The 3 phase will be so much smoother and quiet. Get the VFD for sure. TECO makes a nice unit. Simple to install and many many features can be programmed.

 

[GSPV]

So, the 3 phase runs smoother. Mike Bryant told me on FB that I'll still have enough horsepower. Sounds like the 3P stays and I convert power.

So, VFD is on the list. What are the other options and their pros and cons vs the VFD?

 

[ridgeway]

For what you are doing....no cons with using a VFD that I can think of. You can add a remote pot dial(potentiometer) for frequency control(speed) and utilize your factory drum switch, which must be wired to VFD control side. There is a learning curve getting the control side all wired in to use remote switches and stuff. I guess that would be the only con.

 

[liljoe]

I bought one of these for my mill. Relatively inexpensive and not hard to wire up.

 

[GenePoole]

I like the almost instant stop and reverse when using the VFD as well.

 

[Shrek]

Buy a decent VFD like the Teco not the el cheapo off EBay. The super cheap jobs all look the same because they are. Not even 75/25 parts.

 

[Tim Singleton]

I just changed the motor on mine. Pretty quick and painless

Sometimes wish I had went with a vfd

 

[GSPV]

I’m just about sold on the VFD. I’ll get it cleaned up and check the wiring before I pull the trigger on a VFD. If I buy one, I’ll buy a good one...with good support. I don’t have many toys, but the ones that I have are high quality.
