Motor is "pumping" under load in current control mode. is this normal?

Submitted by etienne on Sat, 2023-05-13 17:16

Hello,

I've built an electrical winch for paragliders with a 12kw hub motor. It is operating with a VESC 75/300.

Today we wanted to test it's drag force before we are actually going to use it to launch a real paraglider.

We attached a "Quad" (a motorcycle with 4 wheels) to the line and started pulling. To measure the drag force in kilogram (or daN) we were using heavily the brake of the quad. 

Flipsky VESC 75200 replacement parts

Submitted by Matt26 on Sun, 2023-05-07 22:54

Hi,

new here not sure if this is the right forum category for this, anyways . . 

I have the older version of the Flipksy 75200 VESC which I blew some components on the back of the board when I tried to run it on BLDC mode instead of the normal FOC. It looks like they are direct MOSFETs? 

Does anyone know where/ and if I could purchase new ones? The number on them is IYR 7769 JHZU 1332, with the Y looking more like a upside down triangle with a vertical line through it.

Hey folks i'm a little stuck.. I was adjusting the shutdown mode on my VESC based esc and I moused wheeled to always_off without realizing I did it and wrote the config.. Only realizing my mistake after I reviewed my settings. I'm stuck with esc shutting down right away. How do I reset this?

DUAL VESC FOR BIDIRECTIONAL ROTATION

Submitted by Khaliduzzaman Mredul on Fri, 2023-05-05 06:46

<p>Hello there. I am complete beginner to vesc.Recently I bought a dual mini fsesc 6.7 140a for the drive system of my battle bot. But the issue I am going through right now is that I am not being able to figure out how to control two motors in opposite direction for steering purpose as the particular esc has only one receiver connector. Can anyone please help me with it?</p>

Hi!
i just got my new awesome vesc 6 pluss however when i try to configurate it i get the errrormessage suggestign a hardware issue..

the message states " reason: high offset on current sensor 2, check for hardware failure. "

the vesc is brand new and never been used, i also have uploaded the most up to date hardware? 

does any one have an idea to what i can do. 

i have previusly had multiple vescs and they have all worked straight out of the box.

thank you for any help best regards Hiorth. 

Bench Testing

Submitted by usaevo7 on Tue, 2023-04-25 16:50

Starting a new project helping a friend get his e-skate setup so Im learning from the ground up.  I checked all his wiring and it looks good.  He has the Flipsky FSESC4.20 100A and 2 - Flipsky 6354 / 190v motors from a few years ago, but they never got the unit running because they couldnt figure out the software setup side of things.  I loaded VESC tool and went step by step as Flipskys youtube video recommended but because the software is much newer things were obviously slightly different looking.  I did get several warnings that the firmware was out of date but Flip

VESC6 with DRV8320

Submitted by cromoly on Wed, 2023-04-19 02:40

Hello,

I have an idea of taking the official vesc 6 schematic (https://vesc-project.com/node/311) and replacing the drv8301 with drv8320.

Assuming that the pcb and the hardware designed correctly, will it work if I just change the hw_60_core.h by using #define HW_HAS_DRV8320 instead of the current #define HW_HAS_DRV8301? Are there any other changes I'll have to make?

Thanks in advance for any help!

[SOLVED] PWM speed control at low RPM

Submitted by comes04 on Sun, 2023-04-16 13:30

Hi evryone, this is my first post, I am very new to the VESC hardware.

I am working on Hw: 60 with Fw V6.02 and have the following issue:

I set up my motor with a power supply, the motor its quite large, 1,9 kW / 6N.m with peak of 18N.m.

Is working with hall sensor and I set up the input to be PPM. My "remote" is an arduino with a potentiometer that send values from 0 to 180.

That is mapped to be Pulselength Start:1,0070ms and Pulselength End 2,0060ms

How does controlling two different motors over CAN bus really work?

Submitted by oangelo on Sat, 2023-04-15 20:05

I have been attempting to understand how VESC operates, specifically how to control two different motors using two connected VESCs via the CAN bus. The documentation is quite brief, and I have not found any useful information. Consequently, I have been trying to figure it out through experimentation on my own.

FloatWheel not balancing, shooting forward

Submitted by EvDeck on Fri, 2023-04-14 22:16

Hey all! New here and need some help. I hope I'm in the right place. 

 

TL;DR my floatwheel turns on, seems fine when using VESC tool (motors turn, gyro and pitch,roll,yaw settings good) but when I try to step on it doesnt balance, just shoots forward or backward. Im not sure what settings need to be fixed.
