    HESC V1 150v 600Amp VESC based motor controller

    @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...

    HESC V1 150v 600Amp VESC based motor controller

    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...

    HESC V1 150v 600Amp VESC based motor controller

    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.

    Axiom: a 100kW+ motor controller

    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

    Axiom: a 100kW+ motor controller

    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...

    Axiom: a 100kW+ motor controller

    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...

    Open source BMS for 48V to 400V lithium-ion battery pack

    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.

    HESC V1 150v 600Amp VESC based motor controller

    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...

    HESC V1 150v 600Amp VESC based motor controller

    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...

    HESC V1 150v 600Amp VESC based motor controller

    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...

    HESC V1 150v 600Amp VESC based motor controller

    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...

    Solar Cars and the HPM3000B

    I was able to spin that motor using custom controller and 180volt to 10000rpm and i set the current to 400amps. I was able to top 135kmph on my bike but the setup was not that efficient ofcourse motor is not designed to run at those voltages. But still it doesnt overheat. Sent from my COR-AL00...

    BESC - beefed up VESC motor controller for high power ebikes

    Hey i am using custom build 100kw motor for my super e-bike prototype. And using golden motor 5kw motor in my daily commuter. As the paltatech is overkill for this motor and vesc6 is not capable of driving this i decided to use your design. Sent from my COR-AL00 using Tapatalk

    BESC - beefed up VESC motor controller for high power ebikes

    WOW ! I would love to test this controller in my mini e-bike project. BDW i build that Paltatech controller and manage to go for 700 phase amps. And that is for my super e bike. It would be great to use your design in my daily commuter. Surely ordering pcb and bom in day or two and keep...
