Hi Guys,
I am having issues with the brakes failing while the motors are really hot (deliberately hot to test functionality) around 90 degrees (thermistors in coils)
And usually only if I have the motor amps set high. Eg above 50A or above.
That flat zone is where the brakes stop working, (-0.1A working). Brakes will fail repeatedly at around 90 degrees but not before.
Failure of FOC mode brake，Fault is Drv
I use VESC tool to test DC motor.If i set duty to 0.7 or high ,can not start motor. If I set duty to 0.2,it’s ok,and then gradually increase the duty,it’s also ok.
Hi,
I have been trying to find the AS5047P. But it seems out of stock everywhere.
What other options are there that would work ? I have been looking at the AS5047D and the AS5058A/B would they work
Thanks

Hello everyone. Are there settings to begin with to control a 350 watt hoverboard motor with a VESC? The motor has 27 stator poles with 30 magnets, it's sensored with hall effect bipolar latched sensors. from previous posts I understand that I should post screenshots with the settings I have been working with, but I have veered so far off course that I think it's best to check for settings to start with (as my settings may have zero logic in them). Many thanks!
Hi,
I wrote this in another post, I guess I need separate thread for it.
Now i want to test Vesc in a hybrid power system, the motor is attached to a small gasoline engine, and it is difficult to detached the motor, so i want to know can i do the motor parameters identification in this mode (with the shaft load).
Wating for your answer.
I have two alien power 80mm motors running in FOC.
I have hooked the sensors up and checked that i can rotate the motor slowly and get 5v on the different hall sensors between the +5V and phase hall sensors, but I've read I should get voltage from hall sensor to ground, can I not operate in this way??
It WILL NOT detect the motor hall sensors in BLDC or FOC mode, and i'm pretty sure i've hooked upeverything right, since i do get output on the sensors when probed with a volt meter.
what the heck am i doing wrong!?
hello everyone i am tauhid from Bangladesh. i have brought a vesc and using it for my Ebike . Now i am having some issues with regenrative braking option as it stopping my bike so quickly that one day my motor mount get stucked in spok . how can i stop this option and let my motor spin freely with wheel after i release my throttle. i am using a 3 pin throttle and using duty cycle mode . min voltage .06 and max voltage 2.60. i dont understand this parameter very good. what can i do to stop this braking option ?
Hello,
I am Uwe from Den Haag, working on Wind Drones (aenarete.eu).
Is there a documentation of the VESC API (application programming interface)?
I would like to control the set speed of a VESC, operating in speed control mode and log the actual speed,
motor current, battery voltage, battery current and duty cycle.
