Hi! I am trying to find a way to run my ebike both with a torque sensor and a twist throttle. So I need both adc1 and adc2 as throttles. Is this possible to achieve somehow?
Hi All,I have just subscribed to your forum
I am a French man living in France an building gyroplane as a hobby
in gyro we need to pre rotate huge rotors before taking of .. after this the rotor spins by itself (so there is not danger to do it because the system does not helps to fly but only to take off)
I'm having a really hard time with PID tuning for this motor. I can't get the speed over 500 ERPM, which is about 0.7mph. I know these won't go fast. They're 10kV so with a supply of 24V works out to about 4.7 mph, I need to get maybe 3 mph. They also jitter a lot at low speed, which I realize with these parameters may be unavoidable. I'm looking for any pointers on getting these to run better under speed control. PID tuning or other settings.

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.
