Subject: VFD for Drill Press


Georgia

I have an old Buffalo drill press I aquired I would like to install a vfd on for phase conversion and speed control.  i would like to run it off of 110 volt.
It is 230V, 3 phase with a 3/4 hp motor.
Would this unit work:

Would all i have to do is is just hook up my wires? It currently has a mag starter but I would think I could do away with that.  I don't know anything about vfd's so I want to keep it as simple as possible.

 

Thanks

Anthony

That drive will be a perfect match. You're right, pitch the mag starter. Use the drive or you may want to mount a remote switch to control the drive. The little twist knob on the drive will be especially handy as that controls the speed. You can go all the way from no RPM to full motor speed with a turn of that knob. You can also use the drive to run the drill press backward if that need arises.

I take it you've done this before Ed?  I've also been curious about doing the same thing to a couple of our JET Drill presses and a couple old Cone Drive horizontal mills here.  Mostly for the easy speed control.  I read somewhere that slowing down via VFD (opposed to cone pulley) does not acutally increase torque, is this correct?

Yes, I've done a couple conversions. I have one on my Jet drill press. 6-pole, 3/4 HP motor that replaced a 1750 RPM, 120V, single phase motor. I also put one on a small lathe that now lives in Canada. Both worked well.

For all practical purposes, the torque stays about the same regardless of speed if you are using it continously. Some drives provide torque boost for a limited time. For many milling, drilling, and other machining operations I'd just as soon have the reductuion in speed without the increasing torque.

I highly recommend them.

Please report on that thing after you use it a month. I bet you think that is pure magic.

Ellis Mfg drill presses use a VFD for speed control. They run off 220 ,though. Hitched up corectly, it should work great.

We have an Ellis drill w/the VFD. You're right, it does work perfectly. Only thing is, our is 110V input. Here's our drill:
