Meddings Cold Saw TL300 / Record TL300

[Agroshield]

With the suds pump on the back of the motor, it might be quite difficult to find a replacement motor in 230v that will still drive it. If you do end up going the new motor route, you might have to change to an electric pump. I think the pumps are almost identical to a mechanical fuel pump.

Once I have blades again, I am going to run the motor set to full speed (setting 2 which relates to ~1450 rpm on the motor).
I am going to drive it with a 240v vfd set to 29hz which will give me two thirds of the motor speed, approx ~960 rpm on the motor. It might even be possible to push the hz a little higher without any noticeable power loss.

That is still faster than the normal 400v slow setting speed of ~720rpm.

Hopefully that way it will be a functional saw without me having to try and source a different motor.

I finally got a 3kw ~230v single phase to ~380v three phase VFD from Aliexpress. Only problem is, I can't really get to the saw with all the ongoing projects in the garage

Was going to go the VFD road myself for my saw but i have decided to go single phase with this flange fitting..

Pardon our interruption...

Nice one, single phase is simpler, but then you have got one speed only. How 'critical' the ability is to change speeds on these saws are yet to be determined.
