Any two legs of a three phase system are classed as single phase. So yes a single phase motor will operate when connected. Be sure to use the proper motor protection devices to control the motor.
In Europe, low-voltage, three-phase, systems are four-wire systems, comprising three line conductors and a neutral conductor. The voltage measured between any two line conductors is termed a 'line voltage', and is 400 V. The voltage measured between any line conductor and the neutral conductor is termed a 'phase voltage' and is 230 V.
For a three-phase, four-wire, system, the line voltage is always 1.732 times larger than the phase voltage.
Yes. 230V line to line is considered single phase power. The 115v half part of that is called split phase. It should not be called two phase, as it is one phase that has been center tapped and grounded at the neutral point - it is still one phase power.Answer230 V is the standard nominal voltage for residences in Europe. 230 V is the line-to-neutral voltage (phase voltage). Low-voltage distribution is by three-phase, four-wire, system with a nominal line voltage of 400 V and a nominal phase voltage of 230 V.

Up to 10 Ampere standard applications are designed with phase power supply.For conducting current larger than 10 A, especially for driving motors in industrial applications, all the applications are normally designed for three phase power supplies.AnswerA three-phase system is more economical, in terms of the volume of copper required (around 75%), than a corresponding single-phase line supplying the same load. Three-phase systems deliver energy continuously, rather than in pulses. Three-phase motors are self-starting and more compact than a single-phase motor of similar capacity. Despite this, 'most' homes don't require three-phase supplies and are provided with a single-phase service (having said that, in some countries, such as Cyprus, three-phase residential supplies are common).
A source of 208 volts can be obtained from any two legs of a three phase four wire 208 volt system. The two legs are classed as single phase 208 volts. The lead tags can be L1-L2, L2-L3, or L3-L1 all of which will give you 208 volts. Any of these lead tags to the grounded star point (wye) will give you 120 volts.
It doesn't need to be converted. The 240 Volt single-phase electricity is there already to operate any single phase devices. New breakers, the right size of wiring and a new wall outlet are what have to be installed to add a new single phase 240 Volt circuit to an existing breaker panel which already has a three-phase supply. For safety reasons only a trained and licensed electrician should work with this equipment. Careful! The statement above can be misleading. The Asker is obviously not from the US, he thinks US 240V is three phase, when its really single-phase. But note that he wants to convert to single-phase with one hot and one neutral. This is consistent with European standards with 230V single-phase where one wire is hot and one wire is cold (neutral). You cannot connect a European 230V appliance directly to US 240V because this would connect a hot wire to the appliance's grounded connection, potentially making the chassis components hot! So, while it is true nothing needs to be done to convert US 240V service to single-phase (because it already is), it is not correct to imply that US 240V can be used where you want 240 volts with one hot and one neutral. This would require an isolation transformer or other approved international voltage converter.

Typically single phase motors go up to 10hp. Wouldn't be very efficient at about 100 amps. A 20hp 3 phase motor at 230v pulls 52 amps. The 10hp single phase 230v pulls 50 amps.
It depends on the voltage of the motor, and whether it is single-phase or 3-phase. A 120 VAC 2HP single phase motor draws almost 20 amps, a 240 VAC single-phase 2HP motor draws about 10 amps. A 480 VAC 2HP three-phase motor only draws about 6 amps.

Absolutely not. In the U.S. all power is 120v on a single line (one hot, one neutral, one ground) overseas all power is 230v on a single line. Will fry your unit. You can however by a step down or up transformer fairly cheaply at radio shack.

415V 3 phase is the line to line voltage. The line to neutral of this supply is 230V single phase. Therefore you use one of the phases and the neutral.
The single phase voltage in India is 230v when we check with the phase and the nutral single line
Three-phase voltage in Germany is 400V, single-phase voltage is 230V.
The single phase voltage in India is 230v when we check with the phase and the nutral single line
6,25AnswerWithout knowing the efficiency of the motor, it's impossible to tell. The horsepower rating of a motor describes its output power; you need to know its input power in order to calculate its current.
because all over the world there is an standard rate of voltage
It depends on the 3 phase inverter. If it is a 3 phase input then you will first need to get a single phase to 3 phase converter to simulate a 3 phase supply, if that is what this particular inverter is intended for then you will have a label saying 230v primary with a L & N connection point, and the output will be labelled as secondary, giving you the inverted power rating. This is a very expensive way of running machinery as the inverted power is no different in conumption to the single phase.
