New batch under production for Hesc v2 126v ,144v and also of hesc mini 126v. The new casings looks super gorgeous. Sent from my POCO F1 using Tapatalk

@scianiac I am not much active here on endless sphere. first pre-production batch have been sent to few OEM's as well as Retail customers. Here are some pictures of pre-production Units The production units are under production and no Pictures of the units are available at the moment. Maybe 2...

i made some changes to layout now the terminals are all in one line and aluminum pcb is used. Here is how this looks now. fets are yet to be finalized i received the PCBs for it and maybe parts will arrive in a day or two. here is how power stage looks now. its a big boi now. 235x130mm to be...

Yes huge progress has been made since then i am attaching some renders here after assembling in solid works and this has got complete design makeover. A bit delayed but got a lot better.

Hey Arlo, i am switching at 16khz. I was thinking of running pwm at 3 times the frequency of control loop. Sent from my Poco F1 using Tapatalk

Thanks for the reply but the problem is that the controller i have uses same power stage as axiom and I don't think i would be possible to bump switching frequency to 100khz with those igbt. So if we can increase dc bus capacitance would it help currently i am using 110uf 600v panasonic caps x 6...

Hey Marcos, i recently sent that palta tech vesc to a friend in germany and he is using it with is 8kw qs mid motor. That motor is very low inductance like 10-15uh and throws abs overcurrent fault with overcurrent upto 1200amps( as seen on typing faults in terminal) is there any way we can run...

hey ENNOID, i want to ask how did you manage to connect 2 ltc6811-1 in daisychain without isolation transformer. i am looking for similar approach to make a 24s bms using this ic but want to keep cost low.

hello guys i was on trip so was not able to reply . here is quick update on power stage. I moved positive and negative power planes to front side and bottom side will be used for all the signals with 2 layer of ground plane shielding the traces on bottom side from any interference. This also...

back side of power stage front side of power stage with closely arranged mosfets with hope this would work. in1 layer will be used as gnd plane for shielding gate drive traces. and it will have cutout in between for phase output as shown here are gate driver traces here is 3d image of...

ans: i have doubled the number of electrolytes. Ans: i am using 2 film capacitors(orange box in 3d render) per phase to overcome power stage impedance. they are more superior than ceramic ones in all category. Ans: i will defiantly consider this option. Ans: do you have some links or...

your point seems to be valid i am switching to 4 layer board with this layout with IN-1 layer set as ground plane which will shield gate drive signals bottom layer will be for bus bars of battery input but these are moved to inner side, top side and IN-1, IN-2 will be for phase output . i will...

hello folks, I am working from sometime on Vesc based motor controller which can do 150volt and 600Amps at phase and 300 amps from battery. I am posting Schematics and features are as follows. Please have a look at them and Guide me if I am doing any thing wrong. 1.130v...
