General discussion

Just wanted to shared my app code to improve control at low speed and provide full stop  with hall sensors only  (encoder would allow to use position_pid instead).

I use "mcpwm_foc_set_openloop_phase" with a current proportional to the difference between the actual position (from hall sensors) and the last angle when motor was rotating.

Hello,

I am planning on building my first project with VESC. I come from a background of plane/boat/racing quad ESCs, which generally accept either PWM or 4-12 channel PPM. Because I would like to use my current 4-12 channel PPM RC Transmitter for my project, I want to confirm I can use this transmitter/controller before purchasing. I can configure whatever frame size/pulse length is needed, but I cant go below for channels. 

Hi,

im on project which includes blcd linear motor. Can VESC drive with these kind of motors? These motor have encoder some models builtin.

Hi in the VESC tool for setting the max RPM it asks for the

number of pole pairs . In my motor there are 36  coils  and 30 magnets

so is it 18 pole pairs  (from the coils)

or is  it 15 pole pairs  (from the magnets ?)

Cheers

Hi guys,

I have an inductance measurement issue with my motor, It doesn't allow me to use HFI.

When I use a ready to run motor from T-motor everything seems fine, but when I try to mount my own motor (stator and rotor hooping), my measured inductance is different from a Dcy to another (picture below)

My motor runs fine at no load, but whenever there is a load it's struggling. Any help please ?

Hi all,

at the moment I am planning a small electric motorcycle (conversion). At this point I am working at the project for more than 1 years now. I checked out different electric motors and inverters. When i found the VESC it sounded really interesting, but when i checked it, there where no VESC with the power i needed.

But now there is the VESC 75/300 and it fits perfect to my requirements.

Hi Ben,

I meet a LOT of WAND connection issues. Which I trust anymore for riding...

Bringing the remote to my face for reading the speed makes the double dots almost freezing (at least they move very slowly).

I can feel dropouts, sometimes no reaction, sometimes latency.

I want to give another receiver module a try.

What would you recommend for the nRF chip ?

This paper is from Ninebot-segway , which made self-balancing vehicle. their driver is very good to control hall bldc/pmsm.

I want to change to position estimation to this algorithm, anybody interested can discuss here.

Hello.

Did some tests today with 75/300 and my 5.5kw brushless motor powered by a 46ah battery.

After a long running time I was surprised to see 1v difference between battery BMS measurement and vesc one (48v in vesc vs 47v in BMS).

Also the mAh consumed 9400 mAh in vesc vs 25000 mAh in BMS!

Anybody can explain why such difference?

Hi I'm kinda new to this and I bought my vesc a while back.

I updated my vesc and can't get through the setup because it doesn't detect any sensors. My motor do not have sensors and I was able to run without sensor beforehand.

Are sensors now required to use the vesc tool?
