Disabling speed cutoff

Submitted by RDN2003 on Sat, 2020-10-24 00:25

I am using a vesc in my go kart and when I reach my top speed, the motor cuts out and only restarts when I release and then press on the gas. I would like the vesc to only cut out long enough for the speed to drop a little and maintain the top speed somewhat like a car's rev limiter. Is this possible?

Thanks for your responses, Ryan.

VESC FOC detecting running flawlessly, motor flipping direction erratically when running in speed and duty mode

Submitted by DMKitsch on Fri, 2020-10-23 21:59

Hi,

I am trying to get my brushless DC motor running smoothly in FOC mode. The motor parameter detection runs swimmingly, with the resistance detected and the spindle spinning up smoothly during the flux linkage detection. However after applying these motor settings, when setting the device to run at any speed, the spindle spins erratically in both directions not even making a full revolution. I've got a video below showing what's happening:

VESC in Road Vehicle

Submitted by hockinsk on Sun, 2020-10-18 13:57

Does anyone know of a VESC suitable for use in road vehicles? I notice the warning in the VESC manuals suggests using one wouldn't satisfy approval for vehicle/road use.

I have a small rear-engined microcar i'm looking at converting to EV. Dual VESC 75/300 would work for my power needs. I read up on the Axiom VESC project but the specs are complete overkill for my needs.

Hall sensors + incremental encoder

Submitted by SAK-SIVAL on Thu, 2020-10-08 18:37

 

I am working on mobile robots and during some phases of operation need high position accuracy in the robot wheels with high torque at low speed, but do not need absolute position.  This is different than robot arms that need an absolute position at startup.

I'd like to use wheels that have an incremental encoder with no index as they are readily available and lower cost.
