Re: VESC in electric bicycle

I've tried all different things with the VESC and the BBS02 to no avail.

I just hooked up the BBSHD just now and the result is the same. The motor "sings" much louder than it does with the original controller.

Re: Noise and low power

Thank you very much, I am using an Arduino-based pre-controller to output the ADC signal for the VESC. This also measures and limits the (battery) current to 30A. I've lowered the settings to 80A phase current (I thought it should be about 3 times the maximum battery current) and 30A batter current....

Noise and low power

Hello, I'm using 4.18 firmware on a VESC driving a Bafanag BBS02 motor. Hallsensors are attached, too Startup works fine mostly. But the motor is quite noisy and power output feels significantly lower than with the original 25A controller. I have identical motors in two bikes right next to eachother...

No more connection via USB (unknown device)

Hi, I have had my VESC for just under two weeks. When trying to reprogram it, it was not recognised by the windows computer anymore (it shows as unkown device) I control the motor via ADC with a signal 1,0V-3,3V When the VESC switches on with battery power, it accelerates to full speed, no matter if...

Re: FOC on Ebike hub Motor

Sorry, for hijacking this thread.
I have a similar problem with an ebike mid-drive motor.
Under load it often doesn't start up and when it does, it's not smooth but comes with a punch.

Re: VESC in electric bicycle

Thanks for the reply. That's exactly, what I just did and it works fine.
The only thing that's problematic, is the FOC without sensors. Starting up seems a little rough and one time it didn't work for a few tries.

Re: VESC in electric bicycle

I am pairing a VESC with a BBS02 right now myself. I am using a Forumscontroller as a pre-controller and could e.g. give the VESC a signal ranging 1-4V to control the current, just like a twist throttle or thumb throttle would. Can anyone tell me, how to make the connection with the VESC, what how t...
