General discussion

Good day,

Hi all,

we have a question regarding the use of the VESC-Controllers for induction motors as we want to build a prototype for a LIM. For this prototype we would like to give out 3 ac signals with variable frequency and a fixed current amplitude.

Is this possible with VESC-Controllers? I've seen that the controller is mainly used for BLDC applications.

Kind Regards,

Marc

Hello everyone, currently I'm trying to build a custom firmware that the goal is to achieve a custom UART message exchange function.

However, I am abit new to the ChibiOS and the VESC firmware, for now I tried few UART functions, e.g.:

sdPut(&SD2,'A');

sdWrite(&SD2, "hello", 8);

to send custom message from VESC to external devices, but no luck.  

The Eclipse compiler sometimes shows error:  note: in expansion of macro 'sdPut'

Any suggestions that how to properly initialize the RX TX port on the VESC ?

Hey guys, was wondering if you all could give me some input as to why my motors are locking up after half throttle I'm attaching a link to show what I'm describing https://drive.google.com/file/d/1EvKGwxf86dwbTogXgoSVm0xCEm8sAPxh

I'd like to setup my VESC 6 with two ADC throttles so #1 goes forward (current control) and #2 goes backwards and can also act as a brake.  Can the standard software do this?  Otherwise, I'd like to program it myself.  Any advice is appreciated.

Would someone be able to point me to the settings to maximize amp/currently flow while full throttle?

I have a 150kv inrunner motor (attached to a paddle board), with a 12s (12c) battery, 44v, 20mamp. The motor can handle up to 120amp.

I am new to VESC, but have used several other CAN bus ESCs in the past.  Pardon me if I ask newbe questions.

I am trying to improve on a FIRST Robotics system that uses the REVrobotics NEO motor https://www.revrobotics.com/rev-21-1650/ and would have used their SPARK ESC but FIRST requires a proprietary heartbeat in the ESC for safety reasons.  I am using ROS for the OS and dont have heartbeat capability.

1) Will the VESC work with the NEO motor on the chassis?  (I assume it will). 

Hi, I have a Flipsky 200a waterproof vesc and I have some weird problems with it.

1. Recently I started using HFI with values fairly close to the defaults on 12s and with a max motor current of 180a. I used my laptop plugged into the USB port to set it up, but when I would push the throttle and the motor would start up, the vesc tool would disconnect. On this Flipsky vesc, all of the data wires run very close to the power in wires, so could this be causing enough noise to mess up the usb connection?

Hey  good people 

I see most of you are expert,   hope I not offend   anyone , but I am loosing my mind.....I am new 

Quick story , bought 2  Fsesc  4.12  for Gokart project and new wheel's hub  800W  13S

On the bench I am  use  PWM controller, to  do proper adjust , because in Gokart I will use my Arduino  project  with PWM output 

So  finally I am  able to  run  both way  my motor hub, but   it always  run full speed  or stop 

PWM mapping see  proper  movement of  PWM  signal ,  max , middle , min 

I am using VESC 4.12 with a hoverboard motor to provide force feedback steering for racing simulator.  The VESC is powered with a 24V power supply, and controled via PWM signal from an Arduino Leonardo board in duty cycle mode.  All works well with the exception when I power up the VESC by plugging in the power supply, I get a sharp movement of the motor about 3 seconds after power up.  This happens weather I have the ESC connected to the PWM signal or not.  Kind of scary if you have your hands on the wheel when it powers up.
