I need your help. :)

For a robotics project, I want to use two VESCs to power two motors. I also need the VESC ​flashed with the servo-out firmware since the steering of the robot will be controlled using the PPM cable of the VESC. My plan is to first flash both of the VESCs with servo-out firmware, then assign a slave mode to one of them and finally connect them via canbus cable. Then, connect the master VESC to the onboard computer of the robot. Does this setup work?

 

Thank you for your help. :)

DRV8302 Gate Pin output waveform is not a normal square wave but a triangular wave.

It always happens in Phase A,and Phase B\C are normal.

I'm pretty new to BLDC motors but I'm trying to learn.

I've been working with the calculator on this site and trying to figure out different combinations of motors, batteries, etc.

I wanted to try a combination with the flipky 6384 motor. https://flipsky.net/collections/e-skateboard/products/bldc-belt-motor-6384-4000w-for-electric-skateboard

Hello,

im user of VESC 4 and here is my setup.

im using ADC + UART

I use Analog Throttle (ADC1 , 3.3v, GND)

I use Bluetooth (5v, GND, TX , RX)

When i power VESC all is good, motor spinning, but when i remove Analog Throttle from VESC, motor rotate with FULL SPEED.

Is there any FAIL SAFE for that ? 

I want to STOP MOTOR if i remove Analog Throttle jack not to FULL SPEED.

Hello Benjamin,

My use case is paragliding towing using current mode to get constant force on the rope. The speed of the motor slowly decreasing when angle of aircraft increases. I noticed some glitches on the ERPM close to switch between observer and hall sensors.

Hello everyone,

I'am using focbox to control BLDC pump with FOC mode. I'am working with VESC TOOL 0.95, FOCBOX firmware: 3.40, hardware 410.

I have a (probably basic) question about BLDC motors:

Motor speed is supposedly given by kV * battery voltage. But the ESC determines the motor RPM through pulsing current to the different windings, right?

Is kV*voltage just the max rpm the motor can run at? Or is a motor with too high kV very inefficient at RPM:s much lower than kV*voltage?

I'm confused, grateful for any kind of clarification!

Would a common ebike/escooter throtle work with the 75/300 vesc 

here is one that I had in mind

if someone Knows where to buy a better twist throtle I would love to hear that to.

I am using the VESC tool to prototype propellor blades and have been using the app to run motors at a specific RPM which I input. This is my main method of controlling motors. 

Hi!

I'm converting a 4000kg (9000 lbs) sailboat from a 12hp gasoline engine to electric propusion. The motor I've selected is the ReVolt RV160-Pro (10kW, 50V BLDC outrunner) and now I'm looking for a good esc to fit.

So, what is a "good enough" option? This is what I'm looking for:
