Third Party Hardware

Hello,

I have a weird little issue with the E-step/scooter I'm building, here's the setup:

-Maytech VESC 4.12  (I tested 2 of these VESC's and both show the same issue)

-Maytech 6374 BLDC outrunner motor

-Throttle is a hall effect sensor throttle connected directly to the VESC via the 3.3V, GND and ADC pins.

-12cell Lipo 12AH (Multistar)

The vehicle drives perfectly, all the way up to top speed, the throttle curve is nice and smooth, from 0km/h to top speed (about 50km/h).

Dear everyone, 

This is my first post on the on forum!

A couple of days ago a purchased a vesc from aliexpress and new powersupply. So now that im testing out my VESC, i sometimes get the problem that the datastream stops working and i have to unpower/power my vesc to be able to see the data again. (also sometimes it randomly reconnects and works again).

HW: 4.12

Firmware: ???(updated with vesc tool)

Hello to all

I had a maytech esc give me fault code drv, so i swapped the drv chip and it wouldn't power on, with the 5v line reading 0.9v. I checked for shorts, and c27 has 7v on one side and 0.9v on the other, I didn't change anything but now the 5v line is at 0.5v. any ideas?

I'll provide pictures of my esc if necessary, but nothing seems overtly wrong, aside from me forgetting copper tape and melting the connectors

Hi Everyone

I am running a longboard with a Flipsky  FSESC 4.12 50A SK8-ESC4 on a 6S setup (2x3S in series).

in the manual it says it is compatible with FOC.

i haven’t tried it as I am scared by the warning that vesc tool gives about 3rd party hardware.

Can anyone confirm that this vesc is fine in FOC mode?

Thanks a lot

Jon

My custom vesc has arrived! And it works pretty well and stays cool even when delivering 2.5kW!! But when I throttle up to 3kW or so, the VESC software seems to be limiting itself. It does it around 50V/95% throttle or a little lower throttle at higher voltages. Here is a video:

Hello guys, I wish my first post in this forum were something more interesting....but well.....

I bought a generic VESC and updated it with the wrong firmware, now I can't connect to the VESC Tool and none of the leds are turning on.

What I did was just connecting the VESC to a 12v bench power supply, updated the firmware and tried to use an electric bicycle throttle to spin the motor.

Researching on the forum, it seams a common problem hahahaha but most people are able to resuscitate it using an STlink-v2.

I use this engine from Scorpion; https://www.scorpionsystem.com/catalog/aeroplane/motors_1/sii-55/S-5535-160KV/  and VESC 6 with AS5047 Encoder on a GoPed scooter. 

Hi there,

First post - so if my question is completely stupid, tell it politely ;)

Hello electronics gurus ! :)

Since a while, I had in mind a project of building a VESC that could drive 2 differents BLDC motors with one MCU. Time has come ! :D

I selected a STM32F405 LQFP100 to manage the additional IO, but still I'm stucked in how I'll be able to deal with the 3 injected ADC channels and 6 phases.

The current firmware uses an injected ADC per motor phase.

Is there a trick ?

Should I use an external IC ? If so, which one ?

Thanks a lot !

Hello,

i'am planning to build my own VESC. But i don't want to use Shunt Resistors in the Phases. 

I know that FOC will not work, but BLDC (trapeziodal) should work.

Is it possible to flash the  VESC Firmware on a VESC Hardware without Shunts?

What would happen if the current measurement Pins are connected to a single shunt in Bat+ line? With INA169 or something else. Just for Current logging/Protection funktions.
