This is a very helpful video. Your explanation and demonstratiion of the mechanical connections with their scope readingsclear and easy to follow. Thank you.
Thanks for another well-produced video, looking forward to the next one. I have a suggestion: On a very technical instructional video like this I prefer not to have any background music. It's probably just my old brain but I find it distracting when I'm trying to concentrate on what you're teaching. Anyone out there agree with me? Ross
Hey Ross thank you for your super thanks and even more important for the feedback. I was thinking about it myself and will certainly do the change in the future.
Awesome video, really enjoyed the detailed breakdown! I’m currently looking to buy a used Tesla SDU (front or back, from 2019 or older) for a project. I’m hoping to avoid any potential pitfalls and would love your advice on what to look out for to ensure I don’t end up with a bad motor. Any tips on what to check or any red flags to watch for would be super helpful. Thanks in advance!
Thank you so much. First I recommend going for the rear motor if you can. Try to get shafts as well as HV cables as they are expensive if you buy them separately. If you will be using Open inverter make sure you use the some form of current limiting device such as high power resistor or a heating element in series when testing for the first time. Make sure that you never open any of the contractors while the motor is running. Check the WiKi for the Open inverter SDU there is a setting that doesn't allow the contactor to trip or even better control contractors externally
Your channel is very helpful, thanks for doing all of this. I have a question about the SDU - BMS communication here. I red on the forums that if you are running the motor and suddenly cut off the power from the batteries, there is some trapped electricity in the motor and it would burn the powerstage of the inverter. I am wandering is it really that dangareous ? Im imagining when driving, the bms decides that the cells are too hot and shuts the contactors. Is it really that much of a problem or do you do something to make the sdu and bms talk to each other and prevent such thing?
I am glad that you have found my channel useful. Yes disconnecting a contactor while you are running the motor may damage the Tesla SDU that is for sure. BMS should take other measures to prevent cells from overheating but do not disconnect the contactor that is for sure bad thing to do. The Tesla SDU earlier versions were not as protected like Model 3 motor I would say and number of people had their motors damaged like that.
@@LatutaEV do you suggest somehow programming the bms to slow down the motor before it shuts the contactor if necessary. I was thinking of making an emergency switch, to shut the contactors in case of a fire or something like that. Maybe if the switch tells the bms to slow down the current to the motor slowly, that should do it.
Your 'Heath Robinson' looks like Damien's OEM !! keep on keeping on . I have a new RWD mid engine kit car frame that motor/inverter would fit in nicely 😉
Hello, can you tell me if regen works with the custom board? Do you know of any parameters you can control with the board? Like regen strength, max rpm, max current draw. Would you recommend this setup for an EV Conversion, or should i stick with motor and controller made for conversions? Thank you
Yes of course regen works. It depends on your background. If you have a willingness to search for answers on the Open inverter forum you can make it work. Knowledge in electronics or embedded programming could be helpful. Otherwise go the full product route. With the DIY approach there is a higher chance of mistakes and even damaging the motor or inverter.
Hello I am your biggest fan. I have front engine from Tesla X and I will make with this motor bench press also. Can you please tell me How should I connect front engine Tesla X as you?
Thank you so much for your interest in my videos. You are in luck with the control of model x motor as it is identical to the model s control set up. I you follow my DIY electric car playlist you should pretty much get all instructions how to do it
Hello Thank you for advice. You change Tesla board for open Inventer board. I will ask why? Will it work with geuniune Tesla board? If you will we can communicate via whats up more direct. Gretating from Slovakia

I am glad you have found it helpful 😀
Wonderful breakdown of how the motor works, I’m currently working on a conversion of my own and am glad to have a guiding hand!
Thank you, I'm glad that video was useful
Really enjoying your project video sharing such detail with us. Thanks for your great effort and explanations
Thanks

@@skyrunner95 yes something like that maybe useful. Also depending on the temperature of the cells BMS may turn off regen and increase cooling.

Wow that's very exciting what model is that the kit car I mean? How do you go about registering it?
Sir is their any link to pcb board
Yes if you Google Damien Maguire GitHub you will find all files there

The problem is how to communicate with the Tesla board. It is very hard to hack into their communication protocol
@@LatutaEV Do you have aby idea how Inngenext and EV Controls manage the communication?
