Having recently been introduced to the idea of VFD's by HFH's lathe thread, I have been pondering its use on a chiller unit. The original (Leroy-Somer) 3ph motor fried itself (after 26yrs!) and finding a replacement seems impossible, particularly in single phase guise. The simplest will be to get the original re-wound, which leaves us back with 3ph, hence the VFD.
Had a look on ebay and it seems only the Chinese ones are listed there, just wondering about buying a a 2hp one for this 1hp motor, on the basis that it would be lightly stressed and therefore might last?
Alternatively does anyone have a link for a quality supplier, where I could get the right size unit with a sensible duty cycle?
As always any thoughts and tips on the subject much appreciated.
