75 / 300 vesc

Submitted by craig w on Thu, 2021-12-16 03:36

Hi

on the 75 300 vesc the are 3 + & -  input cables... i'm running a single 60v 16s battery. Question, do the 3 + cable converge as in parallel on do they have to be in series ie + - + - + -

in the wiring diagram it shows a wire splitter does that mean parallel ?

Vesc Max current 90A Vs ESC Max current 135A?

Hi Guys

First of all, thank you very much for all the content and knowledge that's been shared.

This is my first time posting. I've been trawling through the forum and haven't been able to find an answer.

 

I'm trying to make a jet surfboard for a bit of fun. Decided to go with a VESC as it has far more control than a standard ESC, however....

Axial Flow Pump Project

Submitted by design@imsltd.co.nz on Thu, 2021-12-09 02:05

Hi All

We are experimenting on an axial flow pump using the Flipsky 65121 120kV motor & 200A FSECS (see Image below)

For our testing we used a servo tester to start/stop the motor. This worked OK during our testing.

We now wish to be able to simply switch the motor on/off with a toggle type switch. 

Can anyone offer a way we can simply switch the motor on/off?

Thanks for that

David

Running PID position Control with FOC sensorless

Submitted by talabo on Fri, 2021-12-03 17:21

Hi,

I've have been testing PID position control with an ABI encoder (AMT102-V). As there seems to be som unpleasant behaviors at random times, when I have selected the Sensor Mode to Encoder (Motor Setting>FOC>General>Sensor Mode). Which made me change Sensor Mode to Sensorless.

My question is. Shouldn't PID position Control still work flawlessly, as long as I have selected Sensor Port Mode to ABI Sensor? (under Motor Settings>General>General>Sensor Port Mode).

 

PPM Position over CAN bus?

Submitted by walleywalker on Thu, 2021-12-02 18:47

Is there anyway to receive PPM (throttle position) info through CAN bus from VESC?   I am looking to implement light functionality like brake lights and would rather run that off the PPM position than things like checking for negative current flow from the motors.

I've noticed that current flow on braking (revserse) is not always negative if you're at a stand still position with no induced roll into the motors, say on a flat surface at a stop sign.

CAN_PACKET_STATUS 1-5 seem only to cover the following outputs.
