Thread: WorkSharp 3000 - anyone who knows about electricty?

The first problemthat you will need to get around is that Amazon won't ship that to Australia. You will needto find another supplier or ship to a middleman.

The voltage is not the only consideration. But the step doen would need to be overrated for starting current and as well, it would need to be continous rated. Not a DIY.

But the yanks don't just run 110volt, they also run at 60hertz frequency, tho I am not sure of this. We run at 50 hertz and over time this would do the machine no good at all.

You could try getting it from here...

from Rutlands.co.uk

It should be 220 v 50 hz and

it's still about half the price of carba tec

Hi Avery, this isn't a problem at all.

IF you PM me and I can tell you how to get around this easily. )

So basically you wouldn't recommend doing it (

I am not a motor winder. I am an electrician and did my time in industrial.

My best guess is that, the motor alone, the steel core laminations in both the rotor and the carcass would start to 'chatter' and overheat. This may not be initially apparent.

The Electronics ... I can only guess at.

However, you could call the manufacturer ... They have already said it would 'kill it'. But you did not ask them why. I would ask them if it is not so much a voltage problem as a frequency problem. They may just be covering their ####, as they have contracts with local distribution agents.

I would question them as to exactly why it would 'kill it'.

If the frequency is not a problem then I would probably go for it ... but you will flying without a warranty ... but for a few 100 bucks does that matter so much ? chances are it won't break down at all.

cool bananas ... greg

By the way Arry ... I don't think Carbatec is ripping you off.

It is just the economy of scale. It costs the same price to manufacture the motor at 110v/60hz as it does at 240v/50hz.

But the difference is that there are 30 times the amount of woodworkers/metalworkers DIYs to defray the costs in the states as there are here.

Anyway ... Here is any OZ supplier that has five different manufacturers Industrial Tool and Machinery

good luck ... Greg

I am happy to say that Carbatec have written to me and the price was an error on the website.

They were not trying to rip anyone off or anything, amended price is $399.

Just as an endnote, I like the WS system but have got their discs and abrasives and mounted them on an arbour on the lathe.

Would work as well on a pedestal drill.

Obviously this is just for freehanding and I've used the setup for flattening and polishing blade backs.

Have now moved on to the Sorby ProEdge system. A lot more bucks but also a lot more applications.

Hi Arry,

If I'm not too late to chime in on the frequency problem, I'd say that the change in frequency will be an issue. As I understand it an electric motor presents a very small impedance to current flow unless it is operating at it's rated speed. Changing the frequency significantly changes the speed and therefore the impedance.

In layman's terms impedance is the resistance in an (inductive or capacitive) AC circuit. Electric motors don't have any till they are spinning and under power. Basically each time the supply changes polarity (from positive to negative or vice versa) the magnetic field inside the motor from the previous cycle collapses and opposes the new rising magnetic field. This is what limits the current used by the motor. Changing the frequency will cause increased current flow and the motor will overheat. It wasn't always this way. But motors are produced to such tight tolerances these days, there's no margin anymore...

If there are electronics attached to this machine, it's likely that some of the components will fail due to the frequency change too. Anything with a coil in it will suffer as described above as will some types of capacitor.

You'll let the smoke out. Well, that's my understanding anyway...
