And with no grandkids currently on the horizon I have some time LoL. I'll probably post the build on the Tube of You.

Pro tip: when an internal fuse in an electronic device pops (ie one soldered on the PCB that's inaccessible without voiding warranty) there is ALWAYS a reason. Always. Maybe a transistor's gone bad, or a chip is fried. If it was a simple over current event, the manufacturer would have put externally available fuses, for example the glass fuses that some devices have in a screw type terminal.

[@__lasevix_]

Replacing the fuse can also help you diagnose by waiting until it pops again. Or until it doesn't (saved a good few boards like this)

I suspect at higher torques, the magnetic field from the widnings is strong enough to overpower the rotor's magnetic field. That in turn would cause the hall effect sensor to give bad readings. Try running more current through the rotor. Or make another rotor coupled to the alternator, with permanent magents, jsut to drive the hall effect sensor.

[@agingwheels]

A secondary rotor just for the hall effect sensors is genius and something I never considered

[@avaviel]

It might have been the 3d printed parts he used!

[@davelowets]

I think it's more of an issue of interference with the hall effect sensor itself. Either magnetic OR electrical. Electrical shielding of wires, and magnetic shielding for the sensor itself will probably be the key. Add a shield wire to the sensor wires, twist them tightly, and attach only one side of the shield wire to ground. Start with the small things first.

Oof, hall sensor errors have plagued me with Kelly controllers. One thing I’ve noticed is my kelly is incredibly sensitive to hall signals that output a poor signal. Try scoping the hall signal and make sure your hall signals are clean and make a clean transition between high and low. I’ve had this issue in two motors, one was solved by modifying the motor and the other was solved with adding a little capacitance to the hall signal that has the issue. Let me know if you need any help! Edit: I should also mention that Kelly provided amazing product support. Send them an email and Fany will get you sorted.

The way you can persevere through all the issues that arise when prototyping is truly inspirational.

[@fionnbanks-gorton861]

Please just use an induction motor. Synchronous motors are generally used as generators for a reason - the reason being is that the 3 phase power going through the stator is moving too quickly for the rotor, essentially causing excess vibration and little torque. Induction machines do have a term called ‘slip’ - which is when the rotor field ‘lags’ behind the stator field - this means that at as the motor is accelerating (and rpm is close to zero) the natural frequency of the rotor is close to zero hz, while the stator is still operating at its normal frequency. Just look at the torque/speed curve of an induction motor vs a synchronous machine. That’s your reason.

I have immense respect as a fellow engineer for someone starting out in the world of electric vehicles but I do want to mention one thing. The collective view is that anything is better than a kelly controller. I recommend looking into vesc as they are easy to program and provide much more useful information when it comes to error messages and figuring out issues with your components. If you plan on purchasing a new motor for that go-kart look for something in the 5kw range (make sure it has the correct duty cycle) and remember: electric components are limited by heat. If you find a way to cool down your motor, whether it be via a fan or water cooling, you can push your components a heck of a lot harder than spec. Also, If you have issues with your BMS and I recommend purchasing a charger such as a D6 duo that only needs the positive and negative cables (plus balance leads) to charge. It acts as its own BMS for charging and is very safe and highly intelligent. For discharging you can buy voltage testers for the balance leads and set them to warn you when the voltage drops to a low level. Voltage testers are usually 25 cents a pop and reliable in my experience. Also, voltage sag should affect a controller's performance unless there is an issue with it.

That may be necessary due to the alternator windings, wound for a device typically spinning at 2500+ RPM and low voltage/high current. Why do they call those "torque converter"s?

[@IncertusetNescio]

I have to wonder if the hall effect sensors have a functional 'voltage/magnetic range' of input on them. Meaning, how much electricity can you put into the alternator before the resulting magnetic output overloads the HE sensor and gives a bad motor controller reading. In simpler terms, are you EMP-ing the HE sensor and therefore overloading the inputs on the MC? Cursory, completely ignorant, searching indicates sensor power voltages and switching currents range from 3-30v and 1.5ma to 250ma. Not sure what those ranges mean, but I suspect they're related to the HE error you're getting. Additional research reqd.

[@jokumukamikalie]

I'm mostly commenting in the hopes of visibility for your comment and I know nothing about this topic but your explanation would certainly make sense as this issue occurs when applying over "bare minimum" of power. Also, shouldn't it be possible to test it by accelerating slowly on flat ground? If I understand correctly, when the motor draws enough current to make the magnetic fields big enough, it happens at a point which should always be the same speed if tested multiple times under identical conditions? Am I even remotely correct?

[@IncertusetNescio]

@@jokumukamikalie You're mostly there for non-technical talk (I'm not much above that myself). It would be a good test to try, yes. Start on flat and level ground and gradually increase throttle. If it cuts out at a consistent throttle ask, then it may be as I suspect. If not, it is likely some other electrical issue. I'd start with small diameter wiring on up. Interference maybe???

I'll also say that hooking up a DC to DC converter to the BMS has given me trouble, it introduced a weird feedback loop which has almost fried my BMS without any actual load on it. Electricity can get up to all kinds of weird stuff like that.

[@RandomZ88]

Look at where the hall sensors are.... in between the iron holding the coils on the stator. Most commercial brushless motors have the hall sensor far away from the stator coils. I think what is happening is going to the bigger/more powerful controller is causing the hall sensors to trigger on the stator field and they cannot "sense" the rotor field.... Long story short, the stator field is so strong the hall sensors cannot "detect" the rotor as it rotates. Just a thought. Keep up the good work and you will get it eventually. :-)

5 minutes in and I can't decide if I'm more impressed by the editing and production or the sheer amount of effort put into that battery box! Brilliant 😀

This electric go-kart series makes my head hurt. It also reminds me of my semi-frustrating childhood, where spending thousands of dollars and a couple years building something from a combination of junk yard and expensive mail order parts was somehow always preferable for the adults in my world (children of depression era farmers) than just buying something that actually works for less money. But seriously, I wouldn't have had it any other way. Teaching the kid resourcefulness and delayed gratification is a character building lesson. But I hope the kid will get to drive the car before they start high school ;-)

[@lt.schlechtnacht9414]

Lmao I was feeling that the entire time I was watching this series. Im converting a 350 into a vortec 350 out of junkyard parts and expensive mail orders and its frustrating

[@clarkinthedark1]

I’m going through the same thing with my 66 Cadillac. Ditched the carb and added throttle body fuel injection off a 91 Chevy truck. Most of that is okay, but I did a few custom things along the way like an arduino controlled radiator fan assembly. Each time I face a challenge I wonder if I should just go back to the way it was lol

[@lt.schlechtnacht9414]

@@clarkinthedark1 I took a wiring harness off of a 98 silverado 1500 and I'm putting it on my carbed 350, i modified the hell out of the harness. 0411 swapped ecu, multiport fuel injectors with multport intake. Most of it is going ok but sometimes I wonder the samething. Should've I left it how it was? I sometimes wonder that. But considering I'm going to be able to tune the hell out of my truck and have awesome fuel economy and power I think it's worth it. If you need help feel free to ask

[@-IE_it_yourself]

lol yeah. ive been trying to make speakers and i finally made some 150euro speakers that work as well at 300euro speakers, and only spent 600euros on the development.

[@MiniMattTV]

Oh my goodness! That was a ride!! Good luck with it whenever you come back to it. The only thing I’d suggest is that you mount the battery pack to the frame of the kart rather than on the rear axle, then it will have a bit more cushion from bumps and rattles etc.

[@lukawallace5467]

I love how you show your mistakes, it makes the video so much more personable!

[@garysickler2179]

Look at the design of an alternator. The Permanent magnets are triangular and give off power signals under high load that would cause the controller to get confused .

[@BD-xz6te]

You never truly understand a concept until you can explain it to laymen. Good job Mr Dunn.

[@Dozeji]

The sponsor bit.... I am over my head in love with this channel

[@GroupCaptSlow]

There needs to be a crossover with you and Adelaide local celebrity DankPods! He’s got a garbage box car he’s working on on his second channel, just sayin I smell a collab, and stinky headphones

[@RockyFoxxowo]

Let's get some scarlet fire on there

[@thisisnothere14]

Yess this needs to happen!

[@codyols9966]

Your humor keeps me coming back video after video. Definitely one of the best KZbinrs. I really like your other channel too

[@danielsigursson6215]

Apart from the project I just must comment on the absolutely best sponsor plug ever! Editing is awesome also.

[@TheRealCharlieSuper]

If you're ever intesterested in adding more safety to the go-cart, you might be able to add some form of cutoff in the seat belt (when the belt is buckled, allow throttle input), or a safety cutoff in the seat (similar to a lawn mower). My two cents.

[@natel8578]

I'd put some protection between the chain and the high current cabling personally...

[@zdenekberan7002]

As several people have already pointed out, I would recommend using a small external rotor for the hall sensors (it could be just a 3D printed disc) to avoid any magnetic interference from the stator coils. As for the battery connections, even though it must've been a lot of work, the 3D printed clamps are probably not the best idea. 3D printed parts tend to sag over time under continuous force, not to mention that even PETG will get much softer if the battery pack heats up. I understand that you want to do thing yourself and I can appreciate that but in this case, I think it would be best to have the battery pack spot welded properly at a battery repair shop. I hope you don't abandon using the alernator as a motor, I think it's a cool idea. If you wanted to take it a step furter, you could fabricate a new rotor and use permanent magnets which would probably increase the torque and efficiency dramatically. It shoud be possible to use magnets from an old hoverboard wheel if you wanted to keep the cost low. At least you wouldn't have to worry about powering the rotor coil.

[@alexanderwingeskog758]

Sounds like a perfect present when he turns 7. I admire your perseverance! I would probably just go with about 1500 watt engine with an on/off throttle and be done with it... It would be a bit jerky in some situations but would be a lot easier to build.

[@markdesimone9536]

That Nord VPN bit you did was ingenious and so hilarious. You have a great balance of How-to and Comedy. I laughed so many times during this video. Excellent top notch content!

[@killerlawnmower503]

Really like that you also show what did not work as intended. And then problem solutions that might help the error.

[@erichenao6537]

what a crazy time line. I love seeing the hair cut before and after parts.

[@tindalowos]

an alternator rated for way under your voltage will screw stuff up, also the heat from the voltage on those copper strips will cause the plastic to warp

[@Scrogan]

Didn’t know about adding a resistor across the contacter, I’ll have to do that one myself.

[@CinemaEngineer]

I have these same batteries cells. his problem is they can only discharge about 10 amps continuous and 25 pulse. But if at any point the voltage drops below 2v they cut off. A 4p setup would often cutoff for me on an ebike. So a go kart would definitely have that problem.

[@Quintarus1794]

I'm back after the algorithm has led me far afield, and I have to say, I'd forgotten how much I enjoy your editing style.

[@paulheitkemper1559]

How is an old DC treadmill motor not the perfect idea? People use them all the time to turn a normal wood lathe into a variable speed wood lathe. Just needs a cheap little PWM module you can get plans for online, and old treadmills are a dime a dozen.

[@johncoops6897]

It is the perfect idea for a lathe or a treadmill. Nowhere near enough power for this application, plus needs dangerously high voltages (usually 150V or so DC).

[@andreydorovatovskiy2953]

As for the charger, this type of fault is likely because of the blown (shortened) rectifier bridge, less likely there is a short in a capacitor after the bridge or class-x filter capacitor. And please, never replace a fuse with jumper wire, if fuse blows more than once, something else is definitely terribly wrong, I know, I tried it more than once.

[@SchwachsinnProduzent]

One trick I learned in a forum, is to replace the fuse with a 100W light bulb. If it glows, you have a short and if it just gives off a tiny bit of light, it should be fine again. Can save you buying a ton of fuses to test if it is fixed.

[@andreydorovatovskiy2953]

@@SchwachsinnProduzent Yes, it's good old trick, but usually just testing input with multimeter in continuity mode will tell the future in terms of bang at plugging in.

[@TwistedCoiler]

I think you need filtering. Because of how a alternator has to have the rotor charged to 12V to work. The center of the alternator is basically a brushed motor. This may cause electromagnetic interference in the hall sensors. Try adding low value ceramic capacitors between the plus and negative terminal on the 12v in and ground them to the motor case itself. The same way you would see them on older brushed rc cars. Hope this helps. Good luck on the build!

[@the_stixXx]

I love how much you fail and try again. A great example of the process of creating. This is a great video for everyone, especially kids, since this world makes them think that everything comes without effort. Never give up.

Even if he was lousy at making stuff, which he isn't, I would watch just for the editing cuts.

[@nikolaylatev7222]

Amazing videos. Think about if there is any problem using a chain to drive the sprocket. I think using a belt will extend the livespan of the alternator

[@cliffdweller9618]

Hey you're a good dad dude! Your son will be disappointed but hopefully he won't be 7 when he starts Karting. I'm about to start a similar build and your videos will no doubt help me save time and money and frustration, thank you!
