General discussion

Hello,

Hi,

I was wondering if someone knows how to lock the vesc from reconfiguration/reprogramming through bluetooth or only allow certain devices to connect. So that when I leave my bike at a store while shopping not some funny guy will reprogram/reconfigure my bike.

Does someone also know something more about the bluetooth ignition key where a bluetooth connection prevents from current running.

Sorry if I posted it in the wrong section.

I'm use and ESC with VESC in an RC plane. It someone works but if I am going at high power then slam the throttle to zero, the momentum of the propeller spins the prop nut off and the propellor comes flying off. If I slowly back the throttle to zero, everything is fine.  I suspect what is happening here is that when I slam the throttle to zero,  regenerative breaking i causing enough torque in the opposite direction the prop is spinning that if unscrews the prop nut. 

I have a BLDC cordless router from Makita (model XTR01) that I am using in my Shapeoko CNC. I am currently running it off a 24V 350W Meanwell power supply that I have adjusted the voltage down to 21V (the max a Makita Battery puts out) and have wired into the battery contacts. I want to be able to control the router RPM from my CNC control board and not the stupid dial on the router. Sadly the ESC that is built into the thing is potted with a crapton of epoxy resin so I cannot reverse engineer it. Instead I got a purchased this guy:

Hi

I don't want to make a long board or scooter or such , I am actually hoping to use the  controller to run the motor on a gem stone faceting machine that I am building

I want to be able to set the speed  and maybe have it running at that speed for perhaps an hour at a time

My question is , can I use the PWM output from an arduino to set the speed on the controller or if not would a

servo tester output work ?. I cant see how that would be any different to an RC receiver output

Castle (www.castlecreations.com) offers a Motor ( 4-pole, sensored, brushless, 800 KV) that may fit my purpose very good.

Does this 4-pole-scheme impose a problem for my VESC 6+ ? Or does VESC insist on 14-pole-motors.

And is there a way to simulate this motor in VESC-Calculator?

Hello!

I am using some VESC based controllers (from flipsky) on a prototype boat, which is equipped with submersible brushless motors.

I was rather shocked (pun intended) by power in the water from the motors when at zero throttle. I later measurd 12v on each motor lead again the battery's ground (Battery is around 29v) when there is no throttle.

Is this normal operation of brushless ESCs, VESC or is something odd happening? Or could this be a function of the break? I may have it enabled.

Dear All

I would here ask if someone had experience with dual VESC and computer like NUC or Jetson or Raspberry.

I would use VESC for my new project and interested to have your suggestions to decide best suitable options in terms of computer.

Thanks. Regards.

Hey everyone,

I'am trying to utilize the VESC infrastructure in conjunction with a generic 350W 6.5in hoverboard hub motor (27 poles / 30 magnets) at 10s (~37V) in a robotics project. My goal is to reach the slowest possible RPM with closed loop control.

Hi, My configuration is he next, a drone controlled by pixhawk that communicate through UAVCAN to 4 Vesc which command each a motor. i'm having issues about BLDC and FOC nether of them work. I try the parameters detection for both mode, I get parameters but when i try them the motor don't spin correctly: I tried to tune them myself but results are not great.

Is there someone who work on something similar and can gives me some tips? Thank in advance.
