    Just tested HFI on a bench setup - nice work man! It's a definite improvement for low-speed sensorless startup. My larger e-bike motor had some difficulty at first, but adjusting the HFI parameters solved the problem. Works just as well (if not sometimes better) than hall sensors!

      What did you do to get it working ? and did you had the same graphs as in the video ? I'm als trying to get it work on my eBike, but get no good readings and grapsh even if I put the voltage's very high.

    I always appreciate your videos about your changes. Helps me grasp the concepts first, and have a sane starting point and some context. Helps me a lot so ty for sharing. The whole stack is one of my most beloved projects hands down. Always has been. The bar has moved even higher, which is just insane. This is a significant feature worthy of the major bump. I'm so appreciative. I hope you continue to work on whatever you wish.

    this would be perfect for my 3d printed rc car which has the motor directly integrated into the rear wheel!! great work
    i saw someone else do that and they did it without noise, i think its one of the first videos when u type in "sensorless position control" maybe interesting

    Noise and diagram at 16:20 explains everything, really great work. What could be the reason HFI always run in ABS_OVER_CURRENT?

  • @saschaloco1
    @saschaloco1 3 ปีที่แล้ว

    hello I have a question to ask I have performed all the steps of your videos but I find a dangerous disconnection from the remote board that occurs when I brake at high speed surely it is the generative current return that sends haywire you could help me because despite having entered the values ​​you report on your videos I do not solve

    I must be the only one having issues with this process. when i hit te brake icon on vesc tool my motor just does a little click, doesn't engage the brake making this difficult to proceed any further. any tips on what what I'm doing wrong?

    My vesc is cutting out wen I am accelerating and driving over a bump at the same time when this is happening the red led is blinking 4 times I don't know how to solve this problem and I would be happy about some help

  • @victorreppeto7050
    @victorreppeto7050 2 ปีที่แล้ว

    You are controlling position by creating a graph of the inductance over 360° of rotation, If I understand correctly. This seems similar to the steps that a stepper motor is capable of. How many points in your graph? If I use this as an alternative to a stepper motor how many micro steps can I get from this strategy? I don't really need that many because I just want to use it to run a wheelchair or two wheel mobility scooter. I may want to apply it to a CNC milling machine or plasma cutter later on.

    If someone was wondering how to get HFI to work on a 2kg 80100 motor. Set HFI currents (Motor Settings/FOC/HFI) to 30A. If you're using a Lisp script: Don't use (set-current 0), but rather (set-brake some-number) so HFI stays on. If still doesn't work, look at video from 21:05. He uses "foc_plot_hfi_en 1" to plot the tracking data. If that's noisy then your HFI currents are probably too low.

    Hello, I am using a VESC UBOX Dual 75100 and I am trying to configure the electric scooter engine to work with HFI, but my blue dots at the first stage are in random (?) order and they do not change when the motor rotates by hand
    i.postimg.cc/R0zqXLP6/photo-2022-06-09-23-50-05.jpg
    😟
    I tried to look at the "motor position" and turn it: at idle, it correctly shows movement, but as soon as I turn on Full Brake (with HFI), this graph shows something random (along with this, the ERPM values change from -1000 to 1000) and also does not react to the rotation of the motor.😓
    Maybe you have any idea what this might be related to?

  • @vitalibazilevschi3595
    @vitalibazilevschi3595 4 ปีที่แล้ว

    Dear Benjamin, I'm currently working on my Master's degree in "EV torque vectoring" and my Matlab model is almost done. But I strongly desire to build a scale model with individual control on rear wheels. After many attempts to find something suitable I find a bench of BLDC's ESC but with terrible PWM control and also meant decent ESC but very expensive(my University didn't intend to cover expenses).In the end I found your Open source VESC and I was happy to find out it support CAN and many other features.
    My question is: "Does it possible to make possible to send PWM or even directly rpm parameter and receive backward other parameters such as speed (rpm); current back from VESC to Master Microcontroller (in my case NUCLEO-F746ZG
    ) via CAN? "
    Please also mention what hardware revision and software revision does support that future.

    • @RoadSurferOfficial
      @RoadSurferOfficial 4 ปีที่แล้ว

      Yes, but there is very little documentation on implementing this. You can use serial or CAN bus. The tutorial is on his website.
