Induction motor to generator

[Guruji]

Hi guys I want to use a washing machine motor to a generator. I read that with capacitors this can be done.
I have eight connections coming out of this motor.
Anyhelp please?
Thanks

8 connections

the 8 connections is a but not normal most have four, there is 2 sets of wingdings use a ohm meter to find the leads to the coils you want the one s that are around 1.3 ohms the other is higher maybe 4.5 ohms. the other 2 leads are a Speed switch and a Hi temp shut off sensor I think not sure you might look up the motor model # on the net that may give some insight.

Thanks tecknomancer for the links. With ohmmeter I measured two wires and were around 124ohms and another 170ohms. Tried to connect two of them and tried the generator but nothing came out and changed the other two but no generation
The prime mover is another induction motor but it's a bit far from the other cause I read that if prime motor is an induction one can effect the secondary.
Still experimenting.
Thanks

glad to help
first the ohms seem extremely high most of the motors I have worked with are 1/4 to 3 HP and are under 2 ohms so I am not sure about that, but if you have identified the speed switch and you are not connected through it then, you might have armature that is depolarized hit the armature with 12V DC through the winding but don't leave it connected long enough to heat anything up though, just spike it. it is inportant that you only use run type caps Start Caps can explode and the size of the caps are important.

I use Polypropylene Capacitors the 40 µF parallel and the series 150 µF
the DOE PDF is the best resource. I have also used DC caps tied together at the postive and the negative connected to each side of the coil hope that helps they can be hard to get working but well worth the effort

Just curious, have you been able to run a dc drive motor with a surplus of current left over to do other work?

first Guruji not trying to hijack your thread (so sorry but I just will say this)
I have had limited success it seems the rectified current causes the field to collapse or at least I think, so not there yet, it is not cut and dry, if it was some one would have got it a long time ago. but it will never stop me from trying I was thinking hi DC volts low amps and the gear ratio is vary important you can find what I have done on my website and YouTube channel I believe in open source and I will post if I get it

link my last video

sorry the tread is about motor as a generator

Induction generator

I did that hitting the armature with 12v DC but still no success. Yes I am trying for that redeagle cause I saw a guy on youtube who did it that run itself.
I am using electrolyte caps in series about 1000uf 400v.
A guy on internet said that DC caps will work too.
Ok still trying
Thanks

what speed are you running at it needs to be about 40 rpm past what the motor operates at, also series parallel configuration is more stable
good luck

Not sure what speed it's running but it's running quite well with a washing machine motor. The generator has a small pulley too.
I think the problem is the capacitors cause at one time a little voltage was coming.

the operating speed is in most cases posted on the ID plate of the drive motor if not, you may be able to look the model# up on the net there all about the same speed, so the same size motor and pulley may not over crank the generator (just thinking out loud)

maybe this will help

Could not see any id plate with it. The washing machine was an automatic machine Philco W351.
I searched the net on this machine could not find any info on motor .
Try to search more.

ok here goes the largest number of these motors run at 1750 rpm and you need to be at about 1850 for the generator effect to kick in it also does not matter the distance between the two motors for there to be canceling field flow between them try putting an aluminum plate of some size between the motor and the generator unit to break any field interaction it should be good sized like 14 inches by 20 inches and grounded.
hope this helps.

Hi Nueview thanks for help. The primer is a twintub xd-120 motor. I should change it's pulley then cause I did a search on net for it's rpm and found it 1370rpm.
Regarding capacitors if using electrolyte caps in series should I find them same highest capacitance cause if I put one low capacitance it lower all I read?
Do you know anything about the automatic mashine motor wires cause it's have 8 wires coming out?
Sorry for asking to much questions but I want to know these things for generating electricity.
Thanks

Hi to All,
Great thread
I would like to share my test with a 24 v dc speed controller motor
and would appreciate if it can be used to run another motor / gen with caps


cheers
