Default Re: Down until further notice

That is good news Eric. FWIW, we use Variable Frequency Drives (VFD) to control lots of motors in pump stations. For the benefit of those reading, the VFD will convert the line power to DC and then back to AC. You basically are having a computer precisely control the AC output so the quality of the power you are feeding is much better, than the trash going in. I can't recall the last time we replaced a motor on a pump which is run by a VFD- probably never. The drives will shut down before any real damage can occur and give you the trouble info to correct things.

Now the thing that is also helpful is that you can feed single phase power in to a drive and then when it converts the DC to AC you can create 3 phase output. The 3 phase motor is gonna be a much better motor to live with and you don't have start and run capacitors with 3 phase. Just a suggestion to consider for the time WHEN you need to do something again.

Drives are coming down in price every day, and ebay actually can be a great source for something such as this very application we are discussing.
