Electical help RE: creating three phase

[froggyfrenchman]

my point exactly

[pyrocam]

what makes me think its three phase is the 3 power inputs into the coil array and that its a fisher and paykel peice of crap that it is ..... uses a three phase motor perhaps?

In a smartdrive the magnets cover three poles each and that means all three phases at the same time.

The stock standard F&P motor is 3 phase.

The F&P Smart drive washing machine uses an electronically controlled brushless motor which, after rewiring, can serve as an effective three phase permanent magnet alternator to charge a .........

Does anyone know where I can find wiring diagrams for a 240v 3 phase convertor, im still looking

[Ixion]

I believe the motors are polyphasic, with speed controlled by altering the lag between phases. But that DOESN'T mean they run off 440V 3ph. The supply is 230v single phase. Most bike alternators are three phase incidentally. But not 440V

ZING! I just think I figured out how to do it!

the coils are wired in such a way that the go around the ring and come back to the source. so If I seperate the input output wires from the connector point I can make each coil set run on DC

so the coils are going

ABCABCABCABCABCABCABCABCABC...ABC
 ^ ^ ^                                                         ^ ^ ^
   ^                                                               ^
 |----------------These are the same coils----------------|

So two wires are going from the connector to coil set A, one in and one at the other end of the coil.



So If setup a 555 timer, and throw a random voltage (lets say 12 for now) down line A then a few milliseconds later down line B and then Line C then back to A

I theorise that The motor will start a-spinnin'

hope no ones confusing poles with phases . you can get , 3 phase 2 pole 1450 rpm at 50hz , 2 pole 2900rpm at 50hz and 6 pole at 750 rpm.
pyro your an idiot , just get a woman to wash your clothes

even a woman needs a washing machine. I dont go for those butch types you like winja that can use washboards



I am afraid youve got me on the poles there though winja, I dont get those. but my new plan will work, and boy howdy will it work.... (unless someone can tell me why not)

bullshit your showing your inexperience , when my wifes washing machine broke i just got her to throw the washing in the bath tub add water and soap , then got the bitch to hop in and stomp on the clothes like they were grapes , you are never going to be a macho pig like me if you dont think outside the square

[onearmedbandit]

I found my new favourite thread. Thanks guys!

[pyrocam]

I guess her four legs provide more agitation for the clothes winja.


and stuff ya all ya unhelpful louts! Ive gotten the first coil set to run. 2 more and I have a spin cycle

[Sniper]

Well done mate.

[pyrocam]

(he-man) I HAVE THE POWER (/he-man)

I've made it start turning

now to hook up some sort of controller to make them work by them selves (dont want to be touching wires together really quickly to do my washing)

[froggyfrenchman]

you sir, are indeed insane.

[pyrocam]

you sir, are indeed insane.

just wish you could see a better quality image of my first distributor experiment.

it failed insanly since it required four hands to operate it and the brushes were to rigid causing the motor to slow down too much

not to mention the sparks

good fun though

actual 555 timers and relays next time methinks

edit: since you cant see it very well.
its a P120 processor fan upside down with a milk bottle lid hot glued to the top which has bare wire hanging out 1/4th of the diameter and 3 brushes (you can only see two here)

as the fan spins (with a variable resistor for speed) it sends voltage down each of the brushes as it passes it in its turn.

now I had to send voltage down the top of it so the milk bottle lid had power in it, so I hot glued a spring from a high-quality RCA jack to the cap and tied it to the copper wires hanging out the 1/4th diameter of the cap.

the gold thing in the middle is the spring.

the two metal bits hanging out are the brushes

(edit +4 pics)

Classic kiwi number 8 wire stuff there

Just thought I'd point out, depending on your motor tho, unlike DC which is able to load bear and start spining in a set direriction based on electical fields, and AC motor has no starting way to spin due to an alternating voltage.
AC motors contain 2 set of coils, A primary (Main running) and a starter coil, offset by 90 degress (Could be 120)
The way the mashine choses to start is based on how you feed the power into the two coils.
If you contiuosly feed power into the start coil tho, you will blow it.

[Pixie]

The F&P direct drive motor isn't a three phase AC motor at all.
It is a BIG stepping motor, so you have to generate wave pulsed DC for each of the three sets of poles,in sequence.
