General discussion

I have made an electric scooter, using a 12080 motor, the Trampa 75/300 on a 12s battery. I have it running in "current no reverse brake ADC2" with FOC commutation. The scooter works fine, accelerates smooth and fast and brakes well, until going over 35mph or so. At which point using the brake "throttle" (a thumb throttle connected to ADC2) produces a slow clicking from the motor and 0 braking force. It clicks every second or so, until air resistance brings the speed back under 35mph the brakes will suddenly kick in and work as normal.

Hey guys, 

First of all wanted to say that I am very impressed by what you have built here with the VESC tool. 

Hey guys, I am new here so am not sure how this works, but I hope someone can help. 

hello,

G'day,

I saw on the VESC documentation that it is able to provide 3.3V or 5V to external electronics, on the board I'm assuming this is from the section labelled 'sensor.'

Could someone please tell me if and how I can power some of my own electronics from the ESC like an LED strip/raspberry pi/arduino?

Thanks,

Ed

I know this topic has been brought up here a couple of times but I am yet to see a permanent solution to the issue. I am running my custom hardware and everything works great with this just one issue present.

I love VESC, but I'm looking for an ESC which can run at up to 250k eRPM. I have found dated posts which refer to slower speeds, such as 60k, then 150k, and then 200k. What is the current state of affairs? Max speed is both a limitation of hardware and software, so if the software comes close to supporting it are there controllers which have FETs which are better suited to these very fast speeds?

Hello!

Thank you for the patience and care you give to everyone who comes through here.  I hope that my question is easy and well put.

I'm trying to get an ESP8266 to drive a VESC.

I have a 5045/200kv brushless motor on a flipsky (FSESC 4.12 50A Based on VESC® 4.12) with a 2200mAh 11.1v 25C battery.  I have solid blue/green lights on the VESC and I can drive the motor from the VESC tool through a usb-mini connection, so I know the motor/batter/vesc combo works.

Hi all,

i have a custom PCB based on Benjamins 75/300 schematic running. I use it in a underwater diving scooter. I started with some tests in FOC mode, but every time the duty cycle reaches 65% the motor stops with a loud squeaking. I disabled my custom app and control the motor with vesc-tool.

Hello,

I would like to ask for help.
I have Ninebot MAX G30P, and currently, I'm trying to get the motor working with VESC. (I destroyed original ESC)
I want to use FOC control, but I have trouble with detecting motor parameters (after many tries I've got some results, but I'm not sure if they are correct).

The motor itself is rated for 350W (approx 10") with hall sensors I have no other information about it.
When I try to detect hall sensors, VESC is not able to slowly rotate the motor. It starts somewhat jumping between poles.
