In current control, it will compensate the current ki if temp compensate is enabled. Just as followed,
if (conf_now->foc_temp_comp && t > -30.0) {
ki += ki * 0.00386 * (t - conf_now->foc_temp_comp_base_temp);
}
Does the temp compensation really makes sense, and what is the magic num 0.00386 is?
Hi,
I am using a MKSESC Mini V6.7, based on the VESC 6 hardware.
Hello everyone,
I'll start by saying sorry for my poor English and that I'm not using the open source side of this project because my C++ knowledge is none.
So, my problem is that I'm using a TMOTOR U8 KV135 as a starter motor for an combustion engine with a VESC6 MKV (5.3 firmware) and it seems to be a little bit weak for the job.
Hi all,
I'm planning on buying a motor that suggests it should be run with a 250/300A VESC, the motor has a max current of 200A.
In reality I don't plan on running the motor near this current, and will be much closer to a continuous operation of about 50A occasionally spiking to 100A.
The VESC I currently have is the new 75V with 60A continuous capabilities and 120A instantaneous, will I still be good to use this VESC with my motor, as long as I have the current limits set appropriately, or am I missing something?
Appreciate any help,
Morning all,
Interested to know if VESC - or an alternative open firmware - maybe capable of driving a sensored 540 sized 13.5t motor?
Class restrictions specify zero timing, 1s batteries, and selectable Forward/Brake or Forward/Brake/Reverse.
Ultimately I'd like to move from the typical high frame rate PWM control signals over to DroneCAN - or similarly capable open digital protocol and resolve a few minor issues around braking and reverse controls.
I have 3 motors / controllers operating the same way. When I set them to Current mode everything works as expected. Duty cycle will never fully stop spinning and I don't know enough to understand what it's doing. Here's a video of what I'm talking about:
Any ideas on how to make it work correctly would be awesome. Thanks!
Hi, has anyone used a resistor to help brake the motors through the VESC?
My plan was to wire the resistors in parallel with the power supply and use an electronically controlled transfer switch to switch over to the resistors and use the regen braking function.
Here is a simplified diagram of what I am trying to do.
Greetings!
First of all, I need to clarify several things. We're building different 3 phase linear induction and linear permanent magnet motors in our lab. We used;
completely discrete h bridges (3 pieces for each phase)
bldc motor driver from amc (using fake hall input)
and all motors work flawlessly ! of course using sinusoidal or ramp changes motor characteristics but it is another topic.
For our last robotic application, we want to use vesc for linear induction motor.
everything works fine except when ERPM is between 48000 and approx 60000 then the motor is out of sync....(FOC,BLDC,sensored,sensorless...same probleme) !
PLZ Help!!! :)
Hi all
Does anyone know if its possible for vesc to read more that one input from the controller ?
for example I’m trying to set up an tank style control i need
right stick - forward - brake - reverse
left stick - forward - brake - reverse
my board seems to only have one channel input
(Dual FSESC4.20 Plus(Pro Switch)) ?
