Just use any two of the three terminals that are available, this will give you a single phase capacitor.

How single-phase induction motor classified?
The single phase induction motors are made self starting by providing an additional flux by some additional means. Now depending upon these additional means the single phase induction motors are classified as: 1.Split phase induction motor. 2.Capacitor start inductor motor. 3.Capacitor start capacitor run induction motor. 4. Shaded pole induction motor.
What are the Advantage of three phase motors over single phase?
A 3 phase system needs only to use 3 or 4 conductors, as against 6 conductors if it were 3, single phase conductors The amount of copper used in a 3 phase is much less than what would be needed in a single phase system carrying the same current, this reduction in copper allows for weight reduction and cost savings. The power losses in a 3 phase system are much less than in a single phase system.
Want to use 3 phase at home?
I think you will find (in the US at least), that almost all utilities will refuse to provide 3-phase power to a residence. If you have just one thing such as a motor that you need three-phase to run, you can purchase a phase convertor to convert your single-phase to 3.
What would cause an electric motor to run backwards?
Motors running backwards: A DC motor wired backwards or magnetic field reversed. A 3 phase AC motor with 2 phases reversed A single phase motor will run either way unless it is 'persuaded' by means of a shaded pole or other method to rotate in a particular direction.

How do you connected 3 phase motor to single phase power?
Use VFD to make 3 phase from single phase source.

Function of switched capacitor for three phase power generation from single phase?
usually they say its possible 2 convert a 2phase supply to 3 phase.if its so then how?
Why 3 phase and single phase?
3 Phase system is for industrial use and 1 phase is for house hold application
Can you use 3 phase circuit as 3 separate single phase circuit?
yes we can use as a single phase circuit because at practise directly the 3-phase circuit is made by combining the three single phase circuits
What is run capacitor in single phase motor starter with three wire?
A run capacitor and a starter capacitor are not the same thing. A run capacitor is energized the entire time the motor is running, and a start capacitor is not. A run capacitor is one that changes the current on the windings of a single phase AC induction motor to create a rotating magnetic field to energize a second-phase winding. A start capacitor increases starting torque, allowing a motor to be turned on rapidly. It stays in the circuit only long enough to bring the motor to 3/4 of full speed. Some motors then continue to run with a run capacitor.
Does three phase motors have capacitors?
No, The windings in single phase and 3 phase are different. A single phase motor may use a capacitor "start" circuit to create a phase shift between windings and determine the direction it will spin. A 3 phase motor has the windings configured to create a directional rotating field which determines the rotation. The capacitor in a single phase motor is not used to convert it to 3 phase or vice-versa.AnswerIf you have access to a three-phase supply, then you alsohave access to a single-phase supply by connecting your motor to any two line conductors, or between any one line conductor and the neutral. But you MUST ensure that the motor's rated voltage matches one or other of the single-phase voltages available -that depends on what country you live in, because three-phase voltages vary from country to country. And, obviously, if you don't know what you are doing you must consult a qualified electrician.
Do televisions use single-phase or 3-phase power?
Answer 1: TV's use single-phase power. Answer 2: TV's use single phase power of 220 or 110 volts ac power depending on what part of the world you live in.
How do you measure the capacitance of 3 phase capacitor in active line voltage of 3 phase circuit?
You measure the capacitance of a capacitor in an active circuit by observing the voltage across it and the current through it. That gives you, by Ohm's law, the impedance of the capacitor. Plug that in the the equation for capacitive reactance, and you get capacitance. Note: There is no such thing as a three phase capacitor. A capacitor is a two terminal device that resists a change in voltage inversely proportional to its capacitance. You connect one capacitor to one phase. If you have a "three phase capacitor", then you are talking about three capacitors. Deal with each one separately.
How three phase induction motor works without stator?
with 3 phase the rotating field is already set up when power is supplied with single phase you use a capacitor and a second winding to set up the rotating field
Can you convert 415v 3 phase to 230v single phase?
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.
