Hello.

I am considering converting a Woodfast M305 to variable speed. I already have a professional speed controller, but I am not sure how the lathe is set up.

Does anyone have the electrical schematics for this lathe, or know how it is connected ?

Is there a switch disconnecting the capacitor when it has started ?

If there is no switch, and the motor is a true 3-phase motor (After removing the cap), then it should be possible to run it with a frequency converter.

Any thoughts ?

A 3phase motor shouldn't have a capacitor. Capacitors in 3phase power are only used to improve power factor. Aren't needed because you get a bump every 120 degrees. You can purchase them 1phase input and 3phase output. Inverters are readily available on internet auction sites. Hope this is some help. hotwire55

Hello.

Yes, 3-phase motors will have a capacitor, if they are fed from a single phase supply, to create a third phase.
You can use capacitors to improve power factor, but then you have at least 3 capacitors, one for each phase.

I know how motors work, or actually how they can work, but I need schematics or someones knowledge about how the motor on this particular lathe is connected, so I can rewire it from single phase to 3 phase operation.

Hi Eddie 123,
Have you tried to contact Woodfast in Australia? Their email is: woodfast@tpg.com.au Graham and Steve I know reasonably well, Steve is the electronics man you would need to contact, hope this helps.

Hi there.

Thanks for the tip, I have tried to email them before, without getting an answer back, but I will try again.

Hi.

I am getting no reply when I email Woodfast on the email adress before, this is my experience with them from before as well.

Does anyone know emails to some technical people at Woodfast directly, maybe I can finally get some answers to my questions.

Thank you

Eddie
