Three Phase Converter for DP

[Dimitrios Fradelakis]

I found a Powermatic 1150a drill press for sale but it's a 3 phase motor. The HP is listed as 3/4, does anyone have said drill press? If so, what converter did you use? Can anyone recommend a reliable 3 phase converter that won't break the bank?

Buy a vfd. driveswarehouse or factorymation. not only cheap but you can also adjust speed without always changing belts. Dave

I recently put a new VFD inverter on one of my Jet 1642 lathes.

For 1.5HP at 110v I used the KBDF-27D from Electric Motor Wholesale. Came real quick, was easy to wire up. If you search on WoodCentral there are notes from others using other brands and no one seems to have problems.

For 3/4HP at 110v this one (1 HP) will work or you can check to see if they have a smaller one. You can limit the motor amperage to anything that you want for a motor smaller than 1 HP. This model was $190 last I checked.

It wasn't too difficult to program.

I have a Delta 17" drill press with a 1 hp 3 phase motor on it. I used an Automation Direct GS2 11P0 which is 120 volts in and 220 volts 3 phase out. Speed control. forward and reverse, soft start and more. I programed the digital readout to show spindle speed. No more changing belts. Just pick your speed. Really sweet!!!!

I have a couple of rotary phase converters but for your application a VFD would be my first choice.

Definitely VFD, but be careful the motor can overheat when you run it too slow.
