I'm building a three phase rotary converter from plans I have found on the internet.
All the circuits for them are about the same. Heres one.
**broken link removed**
I am trying to understand how exactly it works.
I understand, and have seen how a three phase motor will run on single phase 240 volts to some degree of effency if you spin it to get it started.
What does the capacitor do? I understand a capacitor allows AC current to pass through it. So what does it do that is different then just hooking the 3rd leg of the motor to one of the AC single phase lines? Does it shift the phase of the current enough to sort of mimic actual 3 phase power?
I am also wondering how the run capacitors in the circuit I posted work? How do they change the voltage between the lines?
Not all circuits I have seen use these run capacitors. I am planning to omit them, atleast at first, in my converter.
