Thread: Lathe upgrade HELP - M300
17/11/2021 08:56:54
Posted by Chris Evans 6 on 17/11/2021 08:44:07:

I run my 3HP 14"x40" lathe from a Transwave static box. The motor does not have star/delta windings and I do not know how to find the star point to enable use of a VFD. The only downside I find with the Transwave box is lack of soft start and starting the lathe is a bit fierce at times, if ever it sounds unhappy turning off and restarting usually works.

If the motor ever fails I would look at a motor and VFD package and sell the static inverter (converter ?) but until then I am happy to use the Transwave.

Does your run at every rpm setting this one doesn’t it works fine at 540rpm and below but above that it cuts in and out as if there isn’t enough power

you may be able to view the advert for the lathe

I think the transwave box is a box of capacitors

Hi thank you for your help ! Could some please link me to a suitable VFD?
what is the going rate for a Harrison m300 lathe all seems good but the top slide has a bit of back lash seems to look like the knob unwinds it’s self as the dials gap gets big and smaller depending on the way you wind it in and out

many thanks again

Looking to upgrade my myford ml7 for a Harrison M300 three phase that comes with a trans wave converter to single phase

the only thing that concerns me is that it won’t run any speed above 540 rpm ? It does spin but cuts in and out? Is this because of the single phase converter and it possibly not being man enough?
Any help would be great and how much is a Harrison m300 and transwave converter worth roughly

many thanks
