Hi looking to change 3 phase motor for a 240v, any help much appreciated

Hi Neale and you guys that have helped and thanks for that. Here after a lot of swearing, poor photos and ripped shirt we have a photo of the plate from the geared motor I had to take it off, it was in a pig of a position!

As I suspected, it's a dual speed motor, which are usually only designed for a single voltage.
IIRC it'll have 9 wires in the terminal box, which depending on how they're connected, set the speed.
Don't mistake the number of wires as being a way of changing the voltage like a standard 3 phase motor.

Well m_c thank you for your reply and the info. I will not get to the wires until I get the machines off the deck or stripped down. I take the caution you say on board but it must be I guess why the firm said a VFD was no good. I will contact them again just on the off chance! Many thanks Steve

OK guys

I have an update I am told I need the following
Well the L5-203 will power the first motor and these cost £300+£60 for the ON/OFF, REV/FWD and SPEED POD and the second motor will need the D2-401 and these cost £300 and a POD with REV/OFF/FWD and SPEED is £50 if needed,

I have found a link for one of the items

Just wanted to update you guys as you have been good enough to help me here!

Cheers

You may find it cheaper to get the motor rewound (just google "motor rewinding" for somewhere local) and use a more standard VFD. e.g. one of the common Chinese brand: http://www.ebay.co.uk/itm/2-2KW-3HP-...UAAOSwUKxYeYVQ

Or something second hand from a good brand (e.g. Siemens, ABB, Parker). Unless you are unlucky, the Chinese one will last a long time as you're running somewhat less that its power rating.

The VFDs which accept 240V and output 415V seem expensive for what they are. It's tempting to copy the idea ... or just use a 415V VFD from a suitable DC supply (sometimes works).
