75300 make high pitch after close power switch

Submitted by Kaeomangkon on Sat, 2025-03-08 11:37

I'm using Trampa Vesc 75300 R3 with 60V battery and Golden motor HPM-10kw. It have broken 2 time.

First one

    Using Fw 5.03 permanent close the power switch. tyr to setup FOC and the flux linkage detected is 0.0 mWb then i update firmware to 6.05 everything working well then about 4 hr. I cann't see the status light anymore but there are high pitch sound from vesc and the 3.3 v is short to gnd.

Second one

Hi Everyone.

I'm using two bldc geared motors and two individual vesc v6 as motor controller and i'm using pixhawk to give the signal to motor controller.. i'm trying to do sensorless, abi, and hall. in all the modes i have one common issue

while the robot does a zero turn.. one of the motor cranks and stop spinning(my robot has track system)  
while detecting hall sensor these are the parameters i got

75200 3.3 or 5v short circuit after 10 mins of use

Submitted by Vassily on Thu, 2025-02-27 23:26

So i purchase a 75200 mkesc to replace a 75100 and i just had the time to do 2 acceleration before it stops, the blue led wouldn't go on and i could not connect it by usb.

I opened it and powered it with a stabilized power supply only to find out that the part of the control card that give 3.3v and 5v heats a lot, after searching i found the fe Zener diode in short circuit so i replaced it and now i have the led who light blue but the powered voltage drops from 25 to 7volts and the 3.3 and 5v regulation still heat a lot. 

Dual controller: turn left and right

Submitted by coolic on Tue, 2025-02-25 13:01

Hi everyone,

I'm using Flipsky FT60BD dual controller with my two-motor device (basically a wheelchair). I want the device to turn left and right when sending PPM signal from my joystick. Normally, if you want to turn right the left motor (wheel) moves forward while right motor (wheel) moves backwards (and vice versa). While I was able to get the motors move forward and backwards simultaneously I'm struggling to turn it left or right. Any help would be appreciated.

Connect multiple VESC over CAN bus

Submitted by Anthony20 on Tue, 2025-02-25 02:58

Hello everyone,

I am currently working on a university project where we are trying to build a four-wheel-drive go-kart. Right now, I am testing the system and trying to send a torque command via CAN from an Arduino Nano to two VESC 100/250 motor controllers, but only one motor is running.

When I connect a single motor, it works correctly.

Could you help me troubleshoot this issue?

low speed / high friction startup, max torque

Submitted by schnedan on Mon, 2025-02-24 10:18

Hello all,

Colleagues have procured a VESC-based controller and a model motor (drone style outrunner) as a prototype for a mechanical setup which requires the motor to start with a high torque due high friction. Sensorless. It might not be the best suited parts for the setup, but thats whats on my desk now.

I have put the components into operation and watched some YT videos as well as searched and read everything possible on the subject of VESC and starting with high torque.

But questions remain
