single phase power savings

[jjbeamish]

I think I may have cross pollinated two things.
1st, there is running a single phase motor in ?RV? mode. This requires the step down trafo.

2nd is power savings. Is just easy to do power savings on single phase motors that can be used right away, such as your pump. You do not need the trafo, just caps. Use a switch able cap bank, say up to 80uf, 1/5 or 1uf steps or so, across both hot lines near the motor to find the value that works the best (saves you money and still have power). Then you can replace the cap bank with one or two caps of the same value. I have only tried this with ? hp and less motors. Use 370v oil ?run? caps. The docs (laymen?s and step by step) have nice explanation on how to build a cap bank (thanks Ash). My air compressor is around 1 1/2hp (I can?t recall at the moment, I?ll check) and this did not work but I was trying it at the end of the plug, not at the motor. I have confirmed on other motors that it needs to be close to the motor to work. I will try it on my well pump in my barn as well, I think it is a 1.5hp.

I have never tried anything on 230v.

Thanks for the info Jason!

Is this not the same like Hectors "Transverter" or the "Avramenko plug" ?

If you are using a 1.5 hp well pump in a home setting, this means your well is very deep. I have been in water treatment for over 20 years and have good experiences with pumps and wells, and that size pump is larger than ordinary indeed for a home.

So if you have a very deep well, and you RV your pump, you will get about 3/4 hp or probably less once it is RV'd and this may not be enough to give your home the proper water pressure.

Also, you should already have a pump control unit and in there you should already have a start capacitor and some control electronics.

So be careful if you play around with this type of pump with RV. I personally would not try RV for the first time on my well pump.

Based on Hectors RV and transverter stuff, I have not heard of ?Avramenko plug?.
