VESC silent HFI. Sensorless full torque at 0 speed.

This is a demo of the new HFI methods in the VESC firmware 6.00 beta 40. It works extremely well on most outrunners with some minor tweaking. I didn't even think this was possible before.

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

Thank you so much for this video on hfi and the last 1 that you did it has helped incredibly for me to get the motor running that had lost its whole sensors and helped my understanding immensely thanks!

This is work of a genius kids, so pay careful attention.

Your hardware and software is an art!👍

HI Benjamin, I got the android app and the mac version and I can not get as many parameters on neither of them. Flipsky recomands sticking with fw 5.2... is this what is limiting me from getting all params. I need more torque less speed from my 24volts scooter motor wheels installed in a tank like rover.

Hello, I have a question. I am using the latest version of vesc6 (mks v6.7pro). The angle estimated by the upper computer using the sensorless HFI seems to be inaccurate. It has been fluctuating at a fixed value. The effect is quite different from that in your video. Can you give me some help? The motor I use is DJI's 3508.

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?

[remainsmemories]

Will it work on 4.12 hardware (modes that don't require phase shunts, I mean)

[mikebroom]

Damn! Apparently I needed v6 controllers. too late now!

Currently on FOC with a VX2 remote and a Maker X DV6-PRO ESC. What should i setup so i have some torque at start ?

[open-ats]

where you get all your know how, can u recommend projects, forums, books, code samples?

[nendhang]

where to buy the vesc? 50a maybe enough
