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.

Hi Everyone,

I recently purchased everything I needed to build my own electric longboard and it turned out to be much more of an undertaking than I expected.

I purchased two Flipsky 6354 190KV motors, a Flipsky 4.2 dual FSESC, a Flipsky VX1 remote, and a 10S4P 10.8 Ah Lithium Ion Battery.

The pulley I have on the wheels is 36 teeth and the pulley I have on the motors is 15 teeth.

Hi, 

Hello, Can you help me how to make regenerative braking to Zero x11 scooter? Thank You. 

Im currently trying to connect my esc to the wizard on the vesc tool. For some reason the device will not connect. Message reads please connect vesc via usb port and make sure the vesc is powered on. The vesc is powered on I can see the 2 lights glowing, one green, the other blue. So i know the vesc is powered and i plugged in the USB cord and tried all 3 usb ports on my PC to no luck. Same message, about making sure its powered on and usb plugged in. How do i get this esc to connect to my PC? The auto connect doesnt work, non of the connection methods work.

I managed to brake STM32 MCU by over or under voltage to ADC input. I had jumper wires connected to ADC, 3.3V and GND. Touching ADC with soldering station tip broke the MCU.

After the damage I checked the schematic and noticed that there is not any protection for ESD or over-/undervoltage transients.

Would it be possible to add something to next hardware versions? For example zener-diodes and some TVS? 

Hi,

I'm using an FSESC4.20 on a mid-drive ebike.

I am building an axle out of two BLDC motors from 20v cordless drill. I purchased a dual Flipsky 4.20 50A FSESC. 

I've been able to successfully control each motor independently but not together. At no time has the Vesc tool recognized two motors. I tried several times with the CAN bus switch with no luck. I've tried connecting a CAN Bus cable to both sides but this did nothing. I have a green and blue light on one side and only blue on the other. Now the USB will not let me connect to the side with only the blue light on.
