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

I just read the motor plate which states Delta 240 Star 415 on the main plate

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
Steve

And it's not just a motor, it's a gear motor so no easy swapouts :-(
Re: Hi looking to change 3 phase motor for a 240v, any help much appreciated
I had spotted the other motor but with the correct vfd it could power both, that is why I suggested him to contact the company and speak with them I have answered sues134e in the past and realised he was not hot on electrics. Np disrespect to him.
Re: Hi looking to change 3 phase motor for a 240v, any help much appreciated
Might be worth having a look under the plate over the connections on geared motor to see if delta/star is possible. While it doesn't say it's dual-voltage, it doesn't appear to say that is single-voltage either. Can you post a pic?

Hi Neale going to get a photo a little later mate with a bit of luck just have to move the machine to get in the gap to take a picture. That was a good idea we will see what the picture brings about! many thanks Steve

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