    Wow... This is mindblowing. Never expected one can control a sensorless motor like this.
    Also amazing how the VESC project is going. I saw it first a few years ago, was like "it can't even do field weakening... meh", and now this.
    I work with BLDC motors with encoders and know they can run about like in the video. But doing the same thing sensorless is a whole different story.

    You got me with the full torque at 0 RPM and then you pulled out the perfect position detection... I am blown away and I dont use words like these often.
    All without sensors...its amazing.
    I wish you would develop larger automotive inverter with high Voltage and current.
    I do work in that field and the Commercial inverters are trash compared to yours :D

    Absolutely amazing innovation! You mentioned that silent 45 deg HFI has higher resolution than an encoder and even at "full load" you get tracking (and demoed it). I assume part of the reason for the high resolution is the motor construction? You have 7 pole pair motor so that's 7x the resolution?
    Now.. basic NEMA (hybrid) stepper motors have 50 pole pairs. "Different kind of motor" but actually more like 2-phase close cousins of the 3-phase BLDC motors you've demoed, especially given how modern/chopper stepper motor drivers drive them (FOC). The biggest problem with the stepper motors is that they can lose steps for which the usual fix is expensive servos. But now, how about applying the same silent HFI method in a stepper motor driver to get a very high resolution position (due to high pole pair)? Thus a stepper motor with no step loss (or "encoderless servo")! Which can not only drive to position but can also observe and account for deviations due to load. What do you think?

    Incrediable! Ive been following your work since around the time you first started. I feel privilege to have witnessed it grow. Ive been using your FW to control a kickscooter hub motor for a while. The ability to fine tune the controller to a specific motor is where your FW and tool shines. The more variables available for tuning the better in my opinion. The wizards will get you in the ballpark but man, after learning the how, whys and whats of some of the options Im so impressed with what Ive been able to achieve so far. Thank you!!!!

    I need help, I have a project, a middrive motor for a bicycle, I use a 7070 motor, and a vesc 75100 controller, and a 48v 11ah battery, I noticed that the acceleration is very aggressive, causing the motor to break the reduction clutch bearing that I used it in the project, I already tried to make a negative acceleration curve, and even so, when accelerating, the engine starts very "violent" and gradually increases, I needed it to start very slowly in the first 2 seconds, and only then does it go up acceleration quickly, would you have any tips for me to achieve this? I use a common thumb accelerator!

    I just tried it with a onewheel motor and a Trampa 6-75 using 32kHz ZVF. Inductance is 200uH and Ld-Lq diff is 50. Unfortunately it didn't work at all. Just scary noises at 10% duty or at 4A current. Anything else I may need to change from the defaults for it to work better with this kind of motor?

    I guess it depends on how good your hearing is, because 16khz is still well in my range of hearing. I analyzed the noise a bit, I found that there are sometimes frequencies that go as high as 20khz and more rarely as low as 12khz. Any person under 23 or so can probably hear the loud 16khz... think of the younglings

    As far as I understood, speed is calculated from ERPM, diameter and poles. So max speed is expected to be max ERPM with same calculation. In my setup the motor reaches max ERMP but max speed in diagram is shown much higher. What I'm doing wrong?

    Hi Ben,
    Brilliant work as always on VESC.
    I updated my VESC 6 Mk 4 to FW5.3 yesterday and motor config ran fine however I went to config the App settings today and map my PPM values and I've got a Current Sensor Offset Fault on Phase 3 sensor.
    Is this possibly something FW related or almost entirely HW related and how can I troubleshoot it?
