Craftsman commercial - what 3ph motors do you like?

[bloomingtonmike]

I have a 12" commercial craftsman and a 6" atlas 618. Tonight I got the 618 running. It is powered by a 3/4hp rockwell 3ph motor made by Baldor. Now the Dela VFD that came with my setup was a 1/2hp rated one that was rated for 3ph in. I hooked it up anyway and it runs - for about 2 minutes and then oL errors out.

So I got online and found a Hitachi WJ200 WJ200-007MF AC Drive/VFD rated to 1hp and 110V single phase in and 3ph out - sweet! Also for $20 you can add the speed/hz pot to the faceplate on the WJ200 drives so I am doing that too. So I ordered both of those.

Now my to my 12" atlas commercial lathe - it is single phase 110V. That means all my speed changes are belt changes.

I am contemplating one of two things.

1. Moving the 618's 3ph setup over to my 12" lathe and putting the 110V setup on the 618. I have not measured the spindle dia of the rockwell to see if I can change the pulleys out easy enough. BElt changes on teh 618 are easier than the cabinet on the 12". I got a countershaft so it is pretty easy.

2. Just buying a 3ph motor and second WJ200 VFD/pot setup for the 12" lathe and having both lathes be VFD variable speed equipped.

For those folks who have changed their 12" craftsman to 3ph - what motor have you installed? Is there a nice Baldor or Leeson or Marathon motor setup that fits the bill well for these lathes and their pulleys?? I am a big fan of those motors.

What do you guys use? What motor frame should i look for when sourcing a 3ph motor for the commercial craftsman bench model 12" lathe? Anyone know that off hand?

Another nice 1hp VFD but 220V in - Teco CV-2001-H1

Mike,

It's too late tonight to look up specifics like frame types and so forth but the max horsepower you should put on the 12" Atlas is 3/4. So if the one on the 6" will physically fit, use it (you must already have 3 PH available). The max HP you should put on the 618 is 1/4. If you leave the 3/4 on it, you are eventually going to break it very badly. Reminds me of a friend who once put a turbo-charged Corvair Spyder engine into his VW Microbus. It could almost do a wheelie. He used to love pulling up along side a VW Bug at a traffic light. But every few weeks he had to rebuild the drive train.

Ok thanks for that advice.

I am using a Variable frequency Drive/AC drive to compute the 3-phase from single phase power. Gives great options too like braking, easy speed changes, reversing, and a multitude of i/O options. Super sweet for tools like this.

OK. Sounds like a nice controller.
