Hi Craig


Thanks for the info. We have a 100amp single phase supply. If I remember right I had to put a 50 or 60amp B rated breaker in. For the initial surge.
I believe the motor in the converter is bigger than 5.5kw.

Cheers

The BCH2MR3023CA6C shows 14NM straight through to 3000rpm. Would this be a better option?

Cheers

Strange it says that in the Manual but the torque graph shows 19nm up to around 2600rpm then drops to 9nm at 3000rpm???

Please images of my phase converter temporarily attached to my lathe.

Here is a link to a 15hp one on ebay. Very popular over here.

This is also available 3kw without the brake instead of 3.5kw. Half that price.

Hood

Is 2000rpm enough for you? If so then probably best to go the new route

What do you mean? New route as far as single phase or keeping the phase converter?

Craig

Yes, I do have a digi phase converter from a company called SMP in Stourport. Will send pic tomorrow. would you like a video of the 6kw motor at full Rpm?

Sorry about the link.


My initial thoughts were to get rid of the Phase inverter to use single phase, but Going down the Schneider route leaves me no option but to use a 1.5kw spindle drive which is underpowered over 2000rpm than the F4075 that we have been debating. I totally agree that using the Allen Bradley f4075 and associated drive will work but then I will have to buy these used and wait for them to be available or if I buy new will cost £0000's
If I continue to use the single to three phase converter then I have loads of options including 3 phase which I can buy at sensible money. The link is for a 3 phase 3.5 kw motor with brake. I can buy the recommended drive new for £300. meaning the spindle motor/ C axis would cost £850.

For a novice it would be easier in my mind to stick with the same motors and drives on all axes.

This available on ebay

With this servo drive

Would mean keeping the single to three-phase inverter. I can buy this drive for £300. C axis costing approx £850

Would prefer to get used to programming the one type of drive. Rather than using Allen Bradley and Schneider.

Hi Hood

Please see attached.

The chuck is 150mm. Maybe 1.5 ton certainly no lighter.

Reading back over the posts and reference my last post I presume you are both referring to a 5-6kw servo as opposed to what I have now.
If so it was never my intention to put a 5-6kw servo on the lathe. My preference would be to do away with the phase converter. 

Cheers
Mick

Hi Both

There's been so many posts and loads of information. All getting confusing.

When you saying I can't run a 5-6kw motor from single phase. Are you talking about a servo motor? As I am running the original motor through my Digi Converter with no issues which is 6kw according to the plate.

Hood

The lathe is a Denford Senior 1990. It weighs about 2 ton. It has an X travel 0f 200mm and a Z of around 400mm.

Would the spindle servomotor need a built-in brake?

Cheers
