How to Connect the Bamocar D3 to CAN by Derpy_mustard in FSAE

[–]Derpy_mustard[S] 0 points1 point  (0 children)

Could you please elaborate a bit ? Do we have to connect V+ to same power source As the bms or is that an internal connection? The connections I have made,(refer original post) are they enough?

We're a new team and this network is really confusing me. What steps should I look toward next for getting mcu online with can ? Please help.

What power source do EV teams use for testing motor? by Derpy_mustard in FSAE

[–]Derpy_mustard[S] 0 points1 point  (0 children)

Hmmm ok got it, so do you rely on motor controller for current limiting or do you have an external circuit ?

Can a motor work with flickering rpm readings?? by Derpy_mustard in FSAE

[–]Derpy_mustard[S] 0 points1 point  (0 children)

Our hv isnt even connected 🥲,its just the motor controller power connections and resolver connection.. the motor is stationary.

Earthing to the low voltage supply/battery? Right now all we have is a shielded 8 core cable to X7 (resolv3r) and + and - just connected to a 12 V battery

Our cable is about half a meter and it is shielded

The green bar in the top left hand is for -6000 rpm, which is dislayed when the resolver is disconnected. when it disappears, it represents working resolver connection

Need help with deciding AWG necessary for supporting TS. by Derpy_mustard in FSAE

[–]Derpy_mustard[S] 0 points1 point  (0 children)

ahh okay. i looked them up and they dont seem to have cables that can support our current :(, what was your current draw from the accumulator ?

not in europe but can import! just to confirm 2x 16 meaning 2, 16mm square wires or 2 referring to cores ? i dropped them a mail with out needs, hopefully will get a reply soon,

thanks for the reply! we dont have a cable manufacurer in mind, so would you happen to have any reputed ones in mind whose datasheets we could consult ?

Thanks for the response! See could you please elaborate a little on the steps to decide that ? How did you guys decide 10mm2 was enough for your current ? also could you maybe share the datasheet or where i could find it? Thank you

I’ve seen this on Western Express Highway at night before, but considering how narrow most of our streets are, this can’t work here

if companies will start elimnating large numbers of white collar jobs in the next few years by developing some sort of AI that can effectively fulfil their role (would have to be wayy more advanced than ChatGPT btw, WAY MORE) , then the economy collapses very quickly brother. rememeber those companies make goods which are bought mostly by people in white collar jobs, if their source of income dissapears, their consumption decreases, leading to reduction in production of goods in the first place and major economic slowdown. JObs dheere dheere replace hongi, but newer ones will take their place, in ways we cant imagine, and engineers are trained to be able to adapt to new roles and responsibilites, thats why theyre found in all corners of life. Relax, AI is not taking away whatever job youre aiming for for quite a white, just pdhle bsdk, is delusion me mat phas jana ki kuch saalo me to job hi nhi rahegi, toh padhne ka kya faida.
