3 phase from single phase using scrap parts!

[andrewm196]

@fairyheli2 thanks for the reply , iv tried it with various capacitors and got read outs of 280 upto 610v! so a balance of capacitor values to achieve desired voltage would be required across the phases. if you have a video of your method i ,and many others would like to see it.

[12voltinnovator]

I like how when it's initially started, as it continues to bring itself up to speed it has a boost as if the turbo kicked in which brings it to it's final speed from which it's rated or clocked at.

[Az3arization]

You need a flywheel on one of the motors and both should run at the same 1500 rpm so you would get a 50 Hz cycle current and how did the system run with the small motor unpluged ??

[mythril4]

I made a video, in my profile showing how to simply start a 3phase motor/generator without the use of another motor, check it out.

[foxnad]

can i put that in motorcycle or into a car? then runs electric powered?

[MongoMan95]

@foxnad Yeah just have an electric car with this thing running and you'll get a lot farther than like 100 miles which is the average distance of any good electric car with a full charge which takes like 5 hours and I know this sentence has a bunch of run-ons but I don't care. But yeah it's pretty awesome

[pCneter]

TUT?

[temelcho]

is this free energy or not,thank you!

[andrewm196]

not free energy, just a way of obtaining a very basic 3 phase power supply from 240v single phase.

[madjimms]

@temelcho lol, free energy?

[andrewm196]

@madjimms no,not free energy unfortunately,

[darkstar5d]

so you have both motors hooked up too the main, your testing the blue motor in the bench test sense.

[andrewm196]

not testing the blue no. the blue motor is a 3 phase motor, not capable of starting on a single phase supply without help from a single phase motor or a capacitor start system. the blue motor, once upto speed will run on single 240v supply albeit at around 70% of its rated power, but in this case its being tested to see if it would generate a 3rd 'leg' of power, which it did!, thus powering smaller 3 phase motors.

[Arabhacks]

A 3 phase motor will run on single phase but with not that much torque.

The single phase mother gets things spinning, thereby creating the rotating field.

The ideal solution to your rotary converter is to have a box with 2 time delay relays and a direct drive link plus a guard.

The first relay will drop in upon power up and allow the single phase motor to get up to speed.

Since the 2 motors are already in sync with a direct coupling, the 3 phase is brought up and is in sync.

Relay one drops out.

[bigdady2700]

i love that sound =D

[bigdady2700]

i love that sound =D

[sscholle333]

nice simple example, I just wished i understood the electrical concepts better. do you have a follow up video?

[andrewm196]

@sscholle333 there is another video of mine that shows a slightly more refined version, its runs all i need it to just fitted a cheap 1.1kw hydrovane 3 phase compressor and runs this without noticing.

[fidely]

I would really like to understand what you are doing, but I am not there yet.

[andrewm196]

Respond to this video... 

[Barnekkid]

So is that small motor turning the larger blue one? How does it react when you put a load on it?

[andrewm196]

@Barnekkid a more refined video of mine is on youtube, this might help a little. when a load is put on all that happens is my lights dim in the workshop.!

[spentacle]

@Barnekkid Think of the small motor as a donkey (pony) engine to get the blue one running. The blue one will them RUN on single phase and put out 3 phase to other, smaller 3 phase motors. It's so you can run 3 phase motors from a single phase supply

[juanlify]

[rcee86]

Hi i would like to now and what i need to create 240 volt to run my 220v tig and mig welder?? I have a shop that only provides us 110volts..... i need help!!

[67tr876]

Can i say if some of you want true 3 phase but cant get it why not buy a 3 phase generator ?

[Valrost]

thermo king motor? really? is it just what you managed to get your hands on or do you into transport refrigeration for a living?

[andrewm196]

hello there, yes it a thermo king motor. i believe the model number was an MDII. i scrapped it as i wanted the engine for another project.

[yarrw]

These induction motors have a slip factor. Doesn't that mean the output will be less than 50HZ?

[abzosairis]

i also have this idea, but if the 3 phase motor is delivering power to the single phase motor. what powers the 3 phase motor then? Most of the 3phase motor still turns even if the source is off, and it takes time before it come to rest.

[andrewm196]

no ,you have the idea wrong, small motor is powered from the mains, this 'starts' the large motor which is also powered from the mains 240v/16A supply, we basicly use the 3 phase motor as a generator of the 3 leg of the phase, if you used capacitors etc it would even out the legs etc. but for this quick experiment it proved to me the concept would work. the motor now has been converted into a generator, either single or 3 phase via a number of capacitors, this will be powered by a diesel engine

[abzosairis]

@andrewm196 ah i see! i was thinking that this was a regenerative generator. but thanks man! i learn something from this.

[balloutyves]

Can BOUJOUR, you tell me how the engines are connected? SO LONG YVES

[MrElro449]

mythril4 you are incorrect onthe motor being a 180 out. The reason you heard the motor vibrate was because the the starter motor was spinning faster thanthe 3PH motor was capable of. I use a 3450rpm 3/4 horsepower 115v to spin my 1760rpm 10HP 3PH until i turn on the 220 to the 3PH motor mine does this for a short moment until it slows. A 3PH motor can only run as fast as the rated rpm, if it gets more HZs it will slow, basically killits own power internally until it realigns to the correct rpm.

[basedrum1000]

How can i run that blue motor by gas engine so it will create 3 phase power. I heard something about capacitator connected paralell with engine but only on 1 phase engines. Does anybody know how to do that with 3 phase? sry 4 bad english :(

[faffaflunkie]

Watch those fingers!

[largetraffic]

create your own doesn't anyone get it

electricity is free

[cheetawolf]

sounds like your start motor is having issues...

if ituses a capacitor, i recommend a higher UF or new cap, or else you could burn it up!

[madaboutpix]

COME ON GUYS... you see that a 115 v motor is used to get the three phase motor up to speed. as soon as the 3 phase motor is up to speed it will generate it's own power. the 115 v motor is no longer necessary, he unplugs it.

[SENIORLABONITO]

what is the benefits in this projects of yours

[GrandpaTD]

Do you need to use an induction motor as the 3 phase converter motor or will any motor work?

[andrewm196]

you need a three phase induction motor to generate the 3rd phase.

[balloutyves]

@andrewm196 Hello, am I French, can you make me the electric diagram of the connection of your two engines? Thank you and has soon

[SENIORLABONITO]

do you mean this is a self sustaining motor?

[andrewm196]

@GrandpaTD a 3 phase motor as you need to generate the 3rd 'leg' or phase.

[ThexxGodfather]

is one of the motors providing the power for the other one?

[andrewm196]

both motors are wired into a single phase 240v supply. the large 3 phase moptor wont start without a smaller motor turning it first before its power is switched on. the power from the 3 phase motor can then be used to power a smaller 3 phase motor, although the 3 phase will be out of phase unless capacitors are used etc. gets to technical then! only did it to prove to myself it could work!

[ThexxGodfather]

i had this on my mind for such a long time, i was trying to invent a hoover to work with the same mechanism, if i have the time ill try to make it work , but at some point i might need your help!! ;-)

[hardwares1]

mount the starter motor on a hinge, then you can 'take it out of the loop' after your idler motor is spun up and running...

[andrewm196]

hi there, you are right, but i only quick mounted it on the work bench just to test out the idea!

[123Joko123]

Making an engine start in the way you just did could cost you a finger.

Use an capacitor on the start coil (usually the Z1 Z2 coil, or the thick wire on de solenoid of the 220 motor)

its a lot saver...

[andrewm196]

True! it was the capacitor , i replaced it the next day and all was well! including all my fingers!

[mythril4]

You can run a 3 phase motor on 220V, the second little motor is to get the thing turning as single phase cannot start the motor alone. Wire the motor as if you were using low voltage 3 phase. Connect L1 and L2 to your 220V circut, get the motor spining at a good speed then hit the power it will run. Problem however, you will be running at approximately 3/4 the rated Horse power. The reason you suddenly heard the motor viabrating on his table is because the phase is 180 out instead of 120.

[myrsve]

@mythril4

Right on

[keimel25]

@mythril4 so u saying the torgue will me less??

180 is because u only using to sets of coils right??

[makemydaytoday]

I'll make a video of how to turn 110 volts single phase power into 220 three phase power, It's easy.

I don't have the thing needed, but they are easy to come by, so I'll just show the wiring diagram for it.

Coming soon, watch for it. I see no one on "your tube" has it, so something new!

[McNuggets010]

Can someone tell me what its doing? Also, mabey this is it, but, ive wondered, can you use a motor to power another motor and have the connected with a band like that one and since there powering eacher other they dont need liek external power y'know? lol...

[RODALCO2007]

excellent !!

[jacgoudsmit]

Don't touch that plug while it's still running...

[Mastering3d]

if that blet snaps bye bye hand ?

[andrewm196]

yeah. motor fixed now, capacitor was shot!

no need for hand start.

[jimmykipperfeet]

spot on! hahaha!!

[Rageman1112]

Capicitor start?!

[joecam905]

please show us how you hooked this up.please give more detail.thanks joecam905

[hughheckler]

that is cool to see. Do you think you would be able to charge without stalling out? Even a little charge is a free charge.
