A version off of YouTube that isn't a half hour long! Thank you :)

I’ve Done this a lot and works well on most motors, obviously you won’t get same torque but for certain
Machines you can get away with it

[gyulavarga]

Az ilyen átkötés nagyon nagy teljesítmény csökkenést okoz! Egyik szerkezet sem fog megfelelően üzemelni ami 3 fázisra lett tervezve. Ehhez kell egy megfelelő nagyságú frekvencia generátor ami 1fázis->3fázis üzemet tud! Ez így a 60-as évek buherációja!

note there is no EARTH wire used on this motor, if you wire up any motor make sure a fully earthed cable connected to the frame of the motor.

السلام عليكم.

Commercially branded phase converters are available. Matching them up to the motor and wiring them up correctly is the key to getting the proper phase alignment. No loose capacitors hanging out, everything in a nice safe metal cabinet. NEC compliant.

How does this work?
Well in delta connection, the paticular winding paralleled with power has rated voltage on it. but one winding can't provide rotating megnetic field to start the motor, so with a capacitor in series with the other two windings the current in these windings has a phase difference, which produces a phase-shifted magnetic flux. When this magnetic flux gets mixed with the oroginal magnetic flux generated by the power-line-paralleled winding, a rotating magnetic field appears in the rotor, which gives starting torque. For this part you can refer to why single phase motors need a capacitor. Due to winding current limitation, the motor can only provide about 1/3 of the original rated power.
I'm not a pro but this explains things fine to me.
Accroding to experiences 20-30uF for every kW is useable, the guideline is to ensure that no winding is overloading by monitoring phase current.
Remember to only use non-polarized capacitor such as oil-paper capacitor or metal-film capacitor, do not use electrolytic capacitors or any polarized capacitors for the risk of cap explosion and fire., and the capacitor used should have a voltage rating no less than the power voltage.

Yes correct, it will turn the motor but, you will only be able to drive a very light load. There is very little torque. There are only two ways to solve the problem; 1, buy a single phase motor or 2, buy a variable frequency drive.

[jamalahmed]

I want to learning about the best way of electrical systems for home use program 👍👍👍

[channelview]

By far the best way to do this in modern times is to purchase a variable frequency drive with single phase input. This phase converter stuff was great for 100 years until VFDs became available.

[skeetersaurus]

If VFD's are out of your 'price or availability range', depending on motor size; the best way is to simply build a rotary phase converter using a similar-sized single-phase motor...no (minimal) torque loss that way.

[Friskyrunner]

Syscap is best capacitor brand in India. World class quality.

[davidlixenberg]

I need the science behind any 'trick'.

[mtrevlac]

What is the formula to figure what capacitor to use and will it last as long a cycle as the motor running on 3 phase? I usually have to use a vfd in the situation.

[SafeAndEffectiveTheySaid]

I believe the capacitive reactance must be as close as possible to the values of motor winding ohms resistance

[jboyreal]

How did you calculate the capacitor value you connected

[ModernDairy]

What about the torque when we do this?

[royaddison]

That looks really good but why not just get a phase simulator and use it then your motor will operate properly

[molotontelemaque]

It was counterclockwise first, then clockwise 2nd that's why the rotation was faster at last minute of video careful with tips man, good video though, thanks

[BirukWolde-mnhi]

voltage rating for capacitor should be 250 or 400v?
