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.

Where would power factor capacitors be installed on a 3 phase motor?
Power factor capacitors can be installed on a three phase motor between the motor contactor and the overload heater block.
Examples of three phase balanced load used in industries?
* 3 phase motors * resistance heaters
What are the advantages and disadvantages of single phase and three phase in the electrical supply system?
In Australia most power is generated in 3 phase the split down to single phase wen it reaches individual residences 3 phase power is more efficient to produce. most single phase motors have switching gear and capacitors to help kick a motor on when it starts because single phase power doesn't have enough power to turn over a motor. 3 phase motors are generally simpler and require no starting gear ( normally cheaper to build) Most workshops have 3 phase machinery for the extra power it prvides Some motors can be 2 phase (rare) as well.
Can you run a star motor in delta?
Delta motors should have more starting current than Wye (Star) motors because Delta motors have two windings to take current per phase -- they are wired Phase to Phase. Star motors have only one winding per phase -- they are wired Phase to Neutral.
Can you connect a 3 phase motor to a 1 phase supply?
Single phase to three phaseThe physical internal windings between single phase and three phase motors makes this an impossibility That being said money can make anything happen. Depending on the amount of money you want to spend to make this happen there is a device on the market called a VFD ( Variable Frequency Drive). On the three phase input terminals you apply your single phase voltage. On the output terminals you connect your three phase motor. When run in this configuration there is an internal switch that has to be changed to let the VFD know that it should be looking for only two lines on the input to be hot. Other wise the VFD thinks that there is a line loss on the three phase input terminals and the unit will not start.Some 3 phase motor speed controllers can be run off a single phase supply, this caused us a problem at work when a new speed control was fitted to some laundry equipment, as we then had to rewire the supply to bring in a nuetral, so i suggest a speed controller is probably the solution.
How many microfarad of starting capacitor is best for 15hp 3phase motor?
Starting capacitors are only required for single-phase induction motors. They are not necessary for three-phase motors.
What are three phase motors?
Three phase motors are motors which operate under three phase supply.Each phase is displaced from one another by 120 degrees.It produces three fluxes which are also 120 degrees displaced.
Why would three phase be used instead of single phase?
Three phase electricity is used instead of single phase for industrial situations. Industries use three phase electricity instead of single phase to operate electric motors driving heavy machinery. Three phase electrical motors produce more power from the same amount of electricity and maintain steadier speed. Small portable motors such as drills and mixers use single phase. Motors used around the house are single phase. Motors used to run large industrial machines use three phase.
Is there a single phase capacitor?
All capacitors fundamentally have two sides or "connections" so that any single capacitor will have two terminals. That is true whether capacitors are used in single phase (using one or more capacitors), or in three phase power (same number of discrete capacitors on each phase). The packaging of capacitors is mostly as "singles" having just two connecting wires or terminals, but certain applications - such as three-phase motor speed controllers - often use "blocks" of three or more capacitors, packaged together into one "body" or "casing". Those "capacitor blocks" have four or more connecting wires or terminals.
Where would power factor capacitors be installed on a 3 phase motor?

How do you wire a three phase motor with capacitor start?
I have never come across a three phase capacitor start motor. Any three phase motors I have worked on are induction start.
Why capacitors are not used in three phase motor?
There is no need. The three-phase supply provides a rotating field in the motor, rotating in the right direction, so there is no need for a starting capacitor.
What is the advantages and disadvantages of single phase and three phase?
Single phase inherently requires less equipment (it's cheaper). Three phase motors are more efficient than single phase.
In a three phase four wire wye system having 277V for lighting the three phase motors operate on what voltage?
480 Volt
Are any capacitor in three phase induction motor?
There doesn't have to be but capacitors are sometimes used to correct the power factor.
Why 2 phase induction motors are not used in industries?
A two-phase* system is archaic, and has been completely superceded by three-phase systems, so there is no demand for two-phase induction motors. (*A two-phase generator has two phase windings, displaced from each other by 90 degrees.)
