Single phase is just one phase and neutral about ground potential or supposed to be it can sometimes get a bit up by a few volts though. 3 phase though will make a motor spin 1200 revs a min there abouts without any other bits added the motor is just wound thats the coils and basically a bit inside iron in layers on the shaft. Nothing else. Single phase motors are a bit more complex mainly to get the thing to start spinning
How to convert a single phase AC to a three phase AC?
By using arno converter, single phase ac can be converted into three phase ac. Arno converter is basically a split phase induction motor with an additional winding on the stator for the generating phase. In an induction motor, the rotating field of the stator creates a corresponding field in the rotor squirrel cage too which causes the rotor to start rotating at "slip" speed which is slightly less than the speed at which the stator field is rotating. However, this rotating field of the rotor is additionally utilized in the arno to create power in the generating phase winding which gives the th

How much power can a three phase AC supply transmit?
As compared to a single-phase AC power supply that uses two conductors (phase and neutral ), a three-phase supply with no neutral and the same phase-to-ground voltage and current capacity per phase can transmit three times as much power using just 1.5 times as many wires (i.e., three instead of two). Thus, the ratio of capacity to conductor material is doubled. The ratio of capacity to conductor material increases to 3:1 with an ungrounded three-phase and center-grounded single-phase system (or 2.25:1 if both employ grounds of the same gauge as the conductors).
Why do transformers change the voltage?
At the power station, transformers change the voltage from generators to a level suitable for transmission in order to minimize losses.
Why is a three phase circuit more economical than a two phase circuit?

What is a 4 wire wye?
The four-wire wye system is used when a mixture of single-phase and three-phase loads are to be served, such as mixed lighting and motor loads. An example of application is local distribution in Europe (and elsewhere), where each customer may be only fed from one phase and the neutral (which is common to the three phases). When a group of customers sharing the neutral draw unequal phase currents, the common neutral wire carries the currents resulting from these imbalances. Electrical engineers try to design the three-phase power system for any one location so that the power drawn from each of three phases is the same, as far as possible at that site. Electrical engineers also try to arrange the distribution network so the loads are balanced as much as possible, since the same principles that apply to individual premises also apply to the wide-scale distribution system power. Hence, every effort is made by supply authorities to distribute the power drawn on each of the three phases over a large number of premises so that, on average, as nearly as possible a balanced load is seen at the point of supply.
What is power transfer into a linear balanced load?
Power transfer into a linear balanced load is constant. In motor/generator applications, this helps to reduce vibrations.
