Tratry Radial arm saw II
Hello,
Thanks to all that replied re my saw blade question. Now the next snag: Power. this saw comes with a 3Phase AC motor 3.3 KW 4.5 HP 330/575 V 7.3 AMP 60 CY 90 PF % Obviously way too much for use at home. It is a direct drive motor and I cant hook it up due to its being 3 phase. I have asked around to see about a single phase replacement motor, or re wiring this, but no luck. I know that going to a 1 phase would likely mean less cutting power, but really I can live with that. Any suggestions would be greatly appreciated. |

I would recommend purchasing a Static or Rotary Phase converter. They are sold on eBay all the time or you can get them from Grainger or other vendors. This will covert your single phase power to 3 phase. Additionally, I assume you could purchase a variable frequency AC drive. I plan to purchase one of these for my Powermatic Model 90 lathe that has a 3 phase motor in it. For the lathe, the VFD is good because it has a potentiometer on it to control the speed of the lathe. I wouldn't expect you would need that for an RAS, but you could leave it at a single setting. I expect a rotary phase converter would be your best bet. David |

Replacing motors is *really* problematic with direct-drive. Other than the equipment manufacturer -- *if* they offer anything -- you're probably looking at a "custom" motor re-builder, who _might_ be able build a single-phase assembly around the rotor/stator you have. Be sure you're sitting down when you ask for the price quote. |
