Re: BLDC FOC Acceleration time reduction

Have you tested this Power sump circuit of yours with load?. Is it reliable? I have tested it using a second power supply to apply over-voltage on the VESC side and checked that it caps the voltage and sinks current as it should (I've tested it to 5 A for 10-15 seconds or so). I've also used it suc...

Re: BLDC FOC Acceleration time reduction

coz my ESC resets frequently when i decelerate it instantaneously. Do you have anything that can sink the energy regenerated while braking? If you are using a lab power supply it probably cannot sink current, and if you cannot sink current you will get an overvoltage condition as soon as you do reg...

Re: BLDC tool parameter configuration help

Hi, I tried installing the some compilers for compiling the code after changing the code of shunt from 0.001 to 0.010, but failed. can someone please send the recompiled code for the same. so that I can load it and test it out. coz my ESC resets frequently when i decelerate it instantaneously. refer...

Re: BLDC tool parameter configuration help

Hi, Am new to recompiling, loading the code for VESC. I'm using windows and not familiar with Linux. So, I tried using the "ChibiStudio_Preview17" (http://www.chibios.org/dokuwiki/doku.php?id=chibios:product:chibistudio:start), Then changed the parameter of shunt value to "0.010"...

Re: BLDC tool parameter configuration help

you need to recompile firmware with new current shunt info did you do this? or you only solder new shunts? @artteth Hi, Present operation scenario : FOC sensor mode, Shunts changed to 1 mOhm to 10 mOhm, Firmware remains the same (as for 1 mOhm shunt), 0-60 VDC power source (set to 52 VDC), 2 A cont...

Re: BLDC tool parameter configuration help

hey guys, some good news!! After changing the current sensing resistors, controller could able drive the motor at low speeds as well. Here i was using FOC Control.Thanks to you all guys. I'm able to run my setup with ~50 Grams load from 0 to 12000 RPM in 3 seconds (not actual load but for a test) un...
