I was given it about 6 months ago by an old boy I do some electrics for. I’ve actually got the single phase one working now, it was the contacts on the centrifugal switch. I would however still like to have that speed control from the VFD. Out of interest what motor did you fit? I was thinking 4...

👍👍 I know someone with metal lathe who said they could bore out existing pulley to fit. I just want to make sure of everything before I commit!! Thanks again

Thanks. I think the only difference is the bore on the pulley is 16mm and the shaft on new motor is 24mm. Does anybody know where I could get a pulley made to match my existing one? That way I could always put old motor back on if things don’t work out. Thanks again

These are the plates off lathe. Could I not run the lathe with new motor at full speed , but on the 3rd pulley 1330 on existing motor so when motor is running at full speed it will be at the equivalent to existing motor on 4th pulley near enough. Thank you

Thanks for the information. My single phase motor at the moment runs slow with no load connected, but if I spin it by hand it takes off and runs at full speed. It’s got a single start capacitor, I’ve tested it ( also tried a different one) and that is fine so I’m wondering if it’s the...

Hi all and thanks in advance for any information given. I have a Denford Viceroy lathe with single phase motor and 2 x 4 step pulleys for speed control. I have been given a VFD and a 1.5kw 3 phase motor that runs at 2880 RPM. The max speed the single phase motor and pulleys run at at the moment...
