General discussion

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. 

Hello everyone



my name is Clément and unlike the most popular use case for the VESC I want to introduce this awesome project to a new hobby, namely passenger carrying model trains.

At least here in Germany we use a lot of brushed DC motors to drive our locomotives but the resources for usable motors are getting low nowadays.

Therefore, I want to use BLDC motors to create compact and powerful direct drive bogies. The motors that I plan to use are rated from 24V to 48V < 20A0.

hi, 

trying to get this working. I have a traxxas rc (summit). the radio receiver outputs pwm but your vesc has ppm input. Also trying to use this with navio2 flight controller hat for raspberry pi microcontroller. it also outputs pwm not ppm. i do have a ppm encoder but i currently have it connected from the radio receiver to the navio2 flight controller hat for raspberry pi microcontroller. i can get another ppm encoder to connect the throttle pwm output from the navio2 to the ppm input of your vesc but will it work if i only use it for the throttle?

Hi,

I'm using a Flipsky FSESC4.20 to drive a bbs02 mid-drive ebike motor. I have the bluetooth module working ok. I'm using adc1 for throttle and servo for a brake/cutoff switch. I have the control type set to 'current no reverse brake button'.

This works as expected when connected to the vesc tool app over BT. But if I power up and don't connect the app then the motor will run away when I apply the throttle. It doesn't respond to releasing the throttle and only stops with the brake switch or if I connect to the app.

Hi all! Just got my prototipo and purchased the vesc tool app. I turn the board, Bluetooth and positioning on. I see the board, but connecting fails. I am new to this, where do I find info on troubleshooting? ESC tool does get a connection. Thanks in advance!!

Hello guys.

Hi folks! My VESC 6 has a built-in gyroscope and I can see the orientation of the VESC in my Android app. Is it possible to use this data for stability control of RC cars?

I would like to detect when the car is doing a wheelie. In this case the ESC should decrease the acceleration so that the car does not back-flip.

Hello! I looked at the phases in an oscilloscope when running the motor with FOC. I see block waves and not sine waves. Does anyone know what could be the cause? 

Hello Everybody,

In the VESC 6 MKIV description , it mentioned that the it is able to detect with precision any type of motor including BLDC and DC motors... Is it possible to use an induction AC motor with
this Hw/Tool Firmware ? at least to run it in open loop mode ?
Thank you for your feedback in advance!

I don't know how to interpret charting real time values in FOC bookmark. 

What I and Q values of current/voltages should be? 

Does I or Q components should be small as possible?
