rotoverter for power generation

[revizal]

Hi All,

I bought a new 2HP 3 PH 2840 RPM motor to work in my RV Project. This motor drive my last 2HP 3PH 1400 RPM motor which will act as a generator. I coupled it by belt to get higher power output result. I got virtual circulating power output 2440 watt from 1300 watt input. May be it will give better result if I could tune the cap on the fly.

Hi All,

Here is my last result. The best so far.

Hi All,

Here is the test load of my last RV-Setup.

Hi

I am planning replicate RV for my pool water pump.

please check this webside -http://www.wnysupply.com/index.cfm/fa/categories.main/parentcat/25431
also they are selling unit call Rotary Phase Converter, can I use this phase converter with running capacitor bank for RV replication, .
using only 115 volts instead of 230 Volts ? 

regards

Hi Steve,

If I'm not wrong.. please correct it if I make a wrong understanding.
In a phase converter we need a 3 phase motor act as phase converter (called idler motor) which provide 3 phase power supply to other motor. The idler motor works in idle (without load). The run voltage is the same as the rating on plate motor.
Beside this, in RV-setup you work on 3 phase motor from 1 phase power supply on 1/4 of it's rating voltage. It's not always in idle, but could run in certain load up to 1/4 of the original power rating.

This is important to know the power (in watt or HP) you need in pool water pump application. You have to provide a motor with the power about 4 or 5 times larger than the original power requirement to get efficient system.

So I think you do not need above phase converter kit to make a RV-setup. The main requirement after the 3 phase motor are AC capacitors and switches.

Just my two cent.
