3 speed switch

I've googled for this and it seems like it only works with skateboard remotes.

I ride e-bikes and scooters. I've used a variety of EV grade motor controllers and never run across one that doesn't have at least high and low that are selectable with a rocker switch. Low, medium and high or modes 1, 2 and 3 are very common in controllers. Add the 3 way switch, program what you want the 3 modes to do and off you go.

Stutter start

Howdy!

I'm working on a project that uses a VESC to control a propeller on a dive propulsion vehicle. Normal controllers are hard to deploy so I'm using two switches with different resistors to create a low and high throttle setting in ADC mode.

When I start up, I get a quick stutter I'd like to massage out of the system. Video here:

Anyone have suggestions for what's going on and how I can fix it?

 

Thanks!

ADC Brake while stand , not parking brake

Submitted by spacewalker on Tue, 2021-07-27 08:09

Hi guys 

Just another  brake question ,  as I try to    finish my  Gokart project 

Is there anyone who know how to fix brake / keep motor position while stop ?

I am not   talking about parking brake as it push  20.....50A  to your motor  (depend on settings)  to hold on wheel 

Regen brake is good when you  drive  fast, if slowing down ...and down ...and down efficiency of brake  is going poor and finally  will not stop till 0

what I need  is to apply brake  when is  1-2km/h (190-380erpm) for example) and hold on  the wheel.

FOC HFI Voltage

I have an Outrunner motor that runs at 250v 2a...

I'm looking at VESCtool 'HFI Max Voltage'  but only goes to 15v...

Is this Forum Topic appropriate place to ask?

I did not find documentation parameters in 'Documentation' is there another place to look?

A simple general question is HFI - 'High Frequency Injection' accurate?  Is there a place you define terms?
