When the motor is running, use a meter to measure the voltages between the windings. Change the size of the capacitor to achieve similar values between windings. Incorrectly sized capacitors can cause high voltages and damaged windings. When you have balanced the voltage across windings, like Jean said, it may be necessary to switch in an additional capacitor to provide sufficient starting torque. Like Tamas said, motor will not achieve its rated power. I need to check how this modification will effect RPM. Leave the terminal links in delta as at the beginning of the video. Just move neutral to the other side of the capacitor to reverse rotation. As per A I Reid below - use an inverter for best results !
If you need to run a three phase motor on single phase, get an inverter drive. This is an effective way and you will not lose any power as running on just single phase does. You get the extra benefit of speed control and inherent overload protection. While the above will run it's not good practice.

Hi, this trick works for shot term. If you run your motor for an hour or two you will definitely fry it. Use a frequency converter or disconnect the capacitor with a simple switch right after the full revolution of the motor.
He just wired it wrong for reversing that motor, it will work but half the power of the other direction because he wired as delta for one direction and star for the other, the wiring is the same before but swap the phase and capacitor connection, now you have reversed the motor with the same torque, the capacitor value is approximately 8uf for every 100 watt of motor power, eg 60uf 1hp or 750watt motor.
Yes, to reverse simply move Live wire from U1 to W1 and move the wire of the capacitor from V2 to W2 and the motor torque is maintained. working from his diagram at 4 Mins. 16 sec, in.
How can I use this same motor on a 2 pole 220v connection? I can run a neutral with 2 hot 110’s or preferably with just 2 hot 110’s and no neutral. Thanks in advance!!!
1 important thing that you have to know : If you convert a 3 phase motor by means of a capacitor into 1 phase, then the power of the motor will be reduced to approximately 1/3 of its 3 phase rated power. If you want to load this motor up to its original 3 phase power then the motor will be damaged (slowly burns), so you have to reduce the load on the axis of the motor to 1/3 power. Or else use an Inverter for your 3 phase motor but in this case you have to convert your motor into delta connection because the inverters from 1 phase to 3 phase unable to make higher voltage than theirs input voltage (it is equal to the rated voltage of 1 of the 3 coils of your motor).
How is it Jean B I have a 3 phase fan that I connected according to your video but the fan is just humming but not running I don't have a lot of info on the fan because no specifications on the fan it's self wondering if you could help me
It would be nice if the diagram was a circuit diagram, also showing the alphabetic letters as they appear on the terminal box! Thanks for the video well done!
Dude whats all this u v and w? I got a nine lead wye motor i want to run with my 120 volt wall plug in. Can anyone tell me how to wire it. This is rediculous trying to find a simple explaination.
Yes, correct, you can drive a 3-phase motor using a Capacitor like that. . . . BUT the value of the Capacitor will only be correct for one size of motor and also for only one specific speed or Power output on that motor.. . . These days, it would be better to get a VFD drive unit, which can change single-phase to 3-phase.
Don't know if I am using the wrong capacitors or what could be the problem and I'm plugging into my wall plug that's 30A should I run it from main box, the fan makes as if it wants to start then it just humz then when you put it of you can see it stops
Hi. Short answer is no. You might be able to buy an inverter/VSD (variable speed drive) if the motor can run on it. But this is expensive. If you rewire the motor to run on single phase,you will lose some horsepower thus having to get a bigger motor to start with...
@@bekeconenvironmental3508 No. It would still be a 3phase motor except the voltage would be 230V/3phase. Thus needing a inverter/VSD to switch from single to 3 phase.
@@bekeconenvironmental3508 I would always recommend using an inverter/VSD or just buy the correct motor. I used this motor for a project I ended up scrapping so would have wasted a lot of money buying a motor. In my country and other third world countries (I presume),you use what you have.
@Jean B - Nice presentation style but you could simply move the neutral to the other size of the capacitor to reverse direction. Why conflate Star/Delta with direction change unless you are confused?
Hi In the US we have 2 hots to make 220v. I have a neutral and 2 hots, where would I connect the 3rd wire (perhaps Delta with live, neutral, live, and then start capacitor between neutral and live?)? Thanks
@@CrapInHell (1) Connect the 3 links for delta configuration like in the video. (2) Connect the 2 hot wires to any two of the motor inputs. (3) Connect one side of the Capacitor to the third motor input. (4) Connect the other side of the capacitor to one of the hot terminals for one direction or the other hot terminal for the other direction.
Thanks for the quick response! Do I not need to connect the Neutral line? Will it have enough power to just run with the start capacitor? Thanks again!
@@CrapInHell Leave the neutral open. I am assuming the motor is rated 220/400V, you have two hot phases 120 degree apart. We have single phase 220V hot and neutral 0V so its the same here except using the two hot phases instead of hot and neutral. The main thing is the voltage between the two wires is 220V
With all due respect. Up to 5:00 it made sense and I have been doing the same for 30 odd years with great success. Then you lost it completely by going back to star configuration. Had you simply moved the neutral input to W1 instead of V1 the direction would have reversed and the motor would have run happily ever after.
interesting and verry usefull , i have a drillpress that i need a new condensator for this makes it easy to find the right one a few things i wonder about , does the voltage in the country matter when it comes to the amount of micro fahrad needed ? and if i have a 16 amp fuse at 220 volts i can use about 2500 watt safely (70 percent) without the fuse blowing as soon as you get a peak current draw at startup , will the wattage of the three phase motor be the same with this setup as it would in 3 phase or increase ?
Hi... very informative.. i received a 3ph induction motor which was modded to run off 1ph but i see no cap and direction can be changed/chosen by hand spinning when startup... is it because of missing cap?
You are running in two phase. Cause your motor is 3phase. One phase is missing. Running this motor continuously, you will cause overheating and burn the motor winding. That is why you need this capacitor to compensate the missing phase in order to assist the missing phase voltage supply to the motor, and ease the torque rotation of the motor.
Hi. Any motor's direction can be changed by swapping the L1 and L2 wire. If the motor drives a chain with tensioner,the chain may not be able to go in reverse.
Star connection will give less torque - the function of star and delta is with respect to the line voltage/ motor rated voltage or using star/delta soft starting on 3 phase.
Hi, if it is a 230/400 volt motor and you connect it in star. ( with 230 volt single phase ) it will run on to low current. Just change the wire from V1 to W1 to change direction.
I wrote current i meant voltage ;-) And if you run on 230 volts it must be delta connection. Star is for 400 volts. Running on too low voltage will cause the amps to raise and in the long run harm the motor.
Hi, Thank you for the video. It is very informative. I did follow your step and it worked. But later the motor wont start anymore. Is it because the capacitor or what? Does the capacitor needs to be recharged or not? Please reply me. Thanks!
Hi Naufal If the motor is making a noise as if it wants to start then it might be the capacitor that is faulty. It does not need to be charged. It either works or fails.
