how to convert 1 phase to 3 phase?

Answer 1

one way is to connect a single phase motor to a 3phase generator,

might be a gadget that takes the single phase splits it into three paths, and slews the other two waveforms by 120 degrees....through an inductor or something....but I'm sure it's expensive as crap...

Answer 2

A more reliable way would be to use an AC to DC converter, take the output of that and feed it into a DC to 3 phase converter. This can all be done with solid state electronics. You should be able to get about 80% efficiency, and be able to get lots of power if the components were designed correctly.

Converting DC to 3 phase isn't as hard as it sounds.

Answer 3

Three methods I know are:

Using capacitors to supply a third leg to start the motor

Using a spare 3 phase motor

And an electronic phase convertor.


1 and 2 you can easily make yourself check internet for plans. 2 and 3 will be most effecient, option 1 will run at about 66% of motors power (1hp motor now 2/3 hp)

Answer 4

There are rotary converters that you can buy or even make yourself. The rotary converter use a 3-phase motor and motor-starter type capacitors to generate 3-phase power.

Answer 5

i suppose another way you could do it(though it's complicated and expensive) would be to split the signal 3 ways. The first signal will go straight to the output. Signals 2 and 3 you will convert to digital, then use dsp to add a 120 and 240 degree lag respectively. Then convert these two signals back to analog and add them to the first signal.
