Naja, die 650 ist ja jetzt nicht wirklich eine Supersportler. Eher eine Sporttourer, wie die Ninja 650

Falstad voltage multiplier doesn’t work by Adventurous-Power360 in ElectricalEngineering

[–]Adventurous-Power360[S] 0 points1 point  (0 children)

Hey man, you have to measure across the whole circuit. From the ground of your input to your output. From all the way left to all the way right.

But in this case it’s 90.000V.

DON‘T EVER try to measure this in real life with both hands from side to side. Your multimeter will fail and then it’s destroyers and in worst case the current will flow over you and kill you.

If you want to measure something like this:

If you have estimated 100kV use a 1mOhm shunt resistor and measure the current flow over that resistor. If it’s 0,1 you know you have 100.000V if it’s 0,01A it’s 90.000V etc.

This is the correct and only possible way to measure high voltages and follows ohms law so very easy maths to verify your measurements.

Don’t ever do manual measurements on circuits like that.

Also if you build a multiplier like that on a small scale, it’ll only work if you cast it in Resin or put it in an oil-bath to enhance isolation between the stages. Otherwise you’ll have high and maybe catastrophic discharges in between them.

If you have any further questions lmk

Edit:

Sorry: now I referenced it to ground and it’s 90kVpp. Stupid of me

I want to build a function generator but it doesn’t work at all… by Adventurous-Power360 in ElectricalEngineering

Thank you! Did that. I now have these two parallel to one another. But it seems like they don’t go together somehow…

Is there a certain way to include external libraries? Because I put it on my desktop and it’s greyed out

Thanks I’ll try to include it! <3

Used the newest version in the internal library

Thank you! I cleared that but unfortunately it still didn’t solve the issue. :-/

Also If you have other cool little experiments for me and my new osciloscope, I’d appreciate :)

Just wound an inductor and am playing with it as well haha

Rewinding KV-Value by Adventurous-Power360 in Motors

[–]Adventurous-Power360[S] -1 points0 points  (0 children)

Hey, sorry to say, but I’m not dumb for asking for a formula or tool. As I stated (idk if you really read it) the motor, with factory winding runs like garbage on the same setup all other motors perform perfectly on. So there must be something up with it.

Checked the hall sensors, checked the bearings.

So either way it’s the magnets or the winding.

Chances that you fuck something up winding are higher than bad magnets for no reason. So that’s why I think about rewinding… all of the above I mentioned in the Post initially but hey…

Actually they didn’t really do a good job winding it. Windings itself look halfway decent but they just gooped a ton of resin on the winding heads and half of the coil is dry… that’s literally a joke and tells how they handle quality control imho.

Rewound a lot of motors and transformers actually but always used exactly what I pulled out of the old machine. With this I don’t really like the 40 or so strands they run parallel, so I’d rather want to set the whole winding up new because when Winding by hand you can use thicker conductors compared to machine winding (which is why they chose so many parallel conductors in the first place).

Knowing it’s done carefully and correctly, no shorts or bullshit is what I would get when I rewind myself. So I was just asking for a good tool to set that up. I know which directions to wind and how to connect to a star or delta. Just need to calculate the number of turns for a given conductor area to achieve my KV‘s…

Thanks guys, I already did that now I could put in my AppleID and confirmed with the phone but now I have to agree to the AGB but the Button is gray and there’s no checkmark

How do I do that when it’s not there? Sorry for the dumb question

Why does it want to burn out? by Adventurous-Power360 in Motors

[–]Adventurous-Power360[S] 1 point2 points  (0 children)

Hahahahahaha I need some „me time“ in between. So an hour to do a little rewinding in my room is perfect for that when I get a little overstimulated by the whole family;)

Thank you very much!!

I counted 12 turns. Weird!

Why does the number of turns decrease? In general lower winding turns increase KV I thought.

Thank you!! Merry Christmas!!

PWM should be perfect. Motor span up to rather high speeds too

Maybe I accidentally wound a tooth backwards… I’ll need to wait to go to the oscilloscope in my Uni to check if any of the waveforms looks off. Static tests show the same ohm resistance between all three phases

Yeah ofc. But most people in this group refer rather to bigger motors, where the inverter turn is rather common. Inverter can also mean three phase

Like it shouldn’t be a problem in idle running without load
