Wow Nick, that way a quick relply tar very much.
I can see how I would wire it in delta (i think by watching videos) but I have know idea what a VFD does or what one I would need. Wire a plug is a taxing one for me - not quite but you get my drift!!!
Many thanks
Steve

VFD takes (in this case) 240V single-phase in and produces 240V 3-phase output. As Nick says, you are lucky to have a dual-voltage motor, so change connections to delta, buy a "cheap" VFD (maybe £150 new?) and plug in and go. It's a variable-frequency drive, but in this case you'll set it for 50 Hz output, fixed.

Cheers very much Neale. I understand what your saying you explain it well. I guess I got the wrong end of the stick before beacuse I got in contact with a firm in Notingham and I asked about Jaguar VFD but each one I enquired about they seemed to say it was no good! I will consider myself luck be really pleased if I can buy something for anything like £150
Many thanks Steve

The best bit of advise I can give you if you are not happy with the high voltages involved is ask an electrician to wire it up for you otherwise it could become very costly

Hi Clive, I am the cautious type so I will get someone to wire it up that knows a lot more than me otherwise I could blow the whole lot sky high! Many thanks Steve

You could start by speaking to these people http://www.drivesdirect.co.uk/ and tell them you motor size and what it is being used for.

I take it nobody has noticed the dual low speed motor (for the feed?) makes no mention of voltage?
And I'd guess it will be designed for 380V only.Avoiding the rubbish customer service from AluminiumWarehouse since July '13.

Hi m_c
Thank you for your reply
Yes, you are spot on the motor you refer to is for the feed and I like you bet is it 380V is that a spanner in the works! I thought I was getting off light!
Many thanks

Wiring is easy, LNG from your three pin plug into the VFD and T1, T2, T3 and Earth from VDF to motor, swap any two phase wires to the motor to reverse direction and get forward an reverse how you like it.
If you go VFD try to buy one that has decent documentation, it makes a massive difference when you're getting something working,
- NickYou think that's too expensive? You're not a Model Engineer are you? :D
