how can i get 3 phase from 220?

Answer 1

There are devices you can purchase that convert single pahse power into three phase power. Some use electronics and others use a motor/generator arrangemment. Attached is a link for one. I used the motor version to run a milling machine years ago and it worked fine.

You can also get a 3-phase hookup from your utility, but they will most likely charge for it if itis for a residential service.

Answer 2

No. This 3 phase 220 motor is probably an induction motor. It can't be run on a single phase.I suppose it could be extensive redesigned to work as a single phase motor but the stator windings would have to be rewound and the rotor most likely would have to be changed. It would be cheaper to buy a 120/240 single phase induction motor.

Answer 3

There are two main types of converter.

Dynamic - uses a single phase motor to run a 3 phase generator.

Static - uses electronics to rectify the ac to dc then back to ac, 3 phase. Many small variable speed drives are available as single phase input.

3 phase is often used for high power applications so trying to power these things from single phase may not be practical. Also, contrary to other answers, many power companies will not supply 3 phase to any domestic customer.

Answer 4

You need to have the power company install a new transformer and meter and supply cables. You need to totaly uprade your service entrance and panel. It's a pretty big and costly change. As an option, there are converters available to convert standard household 240 v to 3 phase. This is not real cheap either. Do a search for converters.

Answer 5

i have used rotary converters at remote mountain top transmitter sites. they are noisy and hot because they are only 80 percent efficient, so 20 percent of the electric bill is for waste. they do come in high power versions. not a good idea for home use. i have seen static converters used in office buildings for relative low power applications, say under 2 kw. they are really just an inverter, so buying a 3 phase inverter system might be better for your needs.

Answer 6

How much power do you need? What are you going to connect?

Here is a unit that will operate a 3-phase, 3 Hp motor from 220 volt single phase input:

Answer 7

From the power company

Answer 8

Use inverter, such as SIEMENS Micromaster 420 (obsolete?), OMRON 3G3MV or FUJI or TOSHIBA. Input is 1PH-220VAC-50/60Hz and output is 3PH-380/400VAC-4to300Hz. kW is depends on your inverter capacity (can be as much as 5kW from wall outlet 220VAC).

Answer 9

use a variable frequency drives, it is available from square D and others.

Answer 10

You'll never do that
