Hello everyone
As some of you all know I teach internationally and frequently move from country to country.
Currently I am in a country with 115v AC and 60hz.
I am moving to a country with 230v AC and 50hz
My Glycol cooler for my soft drink bar uses a refrigeration compressor that runs at 115vac and 60hz @ 8a
and the glycol pump is a 1/3hp induction motor that runs on 115vac and 60 hz @ 8a
Now the cost to replace these 2 pieces is cost prohibitive to replace the units with 230vac 50/60hz
So what I want to do is to take my 10kva (10,000w) isolated transformer and drop the line voltage from 220vac to 110vac.
Then I want to take and make a full wave rectifier to convert it from 110AC to 110DC (this will eliminate, or make manageable the flux in the motor)
I was going to add a bank of capacitors to smooth the DC out more.
Here is were I am stuck.
Is such thing as an inexpensive 110vdc inverter to 110vac?? I could even do a 220vdc to a 220vac unit and then drop the voltage with my isolated transformer.
If this does not exist cheaply commercially does any one know what I would need to build one?
My concern is the hertz frequency, I have been told that using a 115vac with 60hz will overheat and destroy my 1/3hp motors on the 115vac 50hz
Other folks say it is not a problem.
It should be noted that the compressor and the glycol pump motor will be running 24/7/365.
Any help you folks can offer would be great. I am not new to wiring things up, my weakness is in the theory of things.
