Third Party Hardware

Hello,

I have a problem with repair my ESC, Hardware version 4.12.
In last year i have accident with broken DRV driver like this (I used the FOC control unnecessarily):

Good evening, 

I've got the FocBox HI100 from Makerx and it based on 75/300. After wrong current settings 2 Mosfets on phase C blowed up. Have anyone 2 or 4 of the irf7759 Mosfets und can sell it to me?

Hi folks, i like to make stuff and i like Power electronics and i have a UNU scooter i want to make some wheelies.

Sooo the idea was to build my own VESC because ist more expensive then buying one und it makes fun.

the first version was made out of parts i had laying around and from old forklift controllers.

For my scooter size is not a big  problem and i want the VESC a bit bigger for thermal Handling

so one PCB for the Power stage and one Logic Board (just like 500A forklift controllers)

Goal... 80V 400 Amps continuous.

I guess i wrote everything in the title I'm super confused super frustrated and don't know what to do I've tried downloading the VSC tool to try to use that and that hasn't worked for me cuz I can't seem to get it downloaded and working and yeah I'm at my Wit's End can anybody help please

Hello guys!

I try to use VESC firmware with my custom bldc controller hardware. I use the latest sources from github and the latest VESC Tool.

The problem now is that when i try to detect motor parameters in FOC mode, i.e. i press "measure R and L" in VESC Tool, all gate signals (GATE_H) are the same, with the same duty and phase, so obviously no current is flowing through the motor and VESC Tool says something like "can't detect motor parameters. R is 0". 

Hello,

I've been looking for a good brushless ESC for robotics projects and the only one I really liked was the VESC motor controller. This is, because it has FOC commutation, automatic motor detection and a digital interface for reading back the current state of the motor (current, voltage, position, speed, ...).

In spite of its perfect software and great hardware, the VESC had a few issues that bothered me for this application:

Hi, I need to deal with a problem I have. I have a scooter FLJ sk3 2x3500W, battery 20S 72V and I bought the driver FS75100. I have 80A set for each motor.
The scooter rides quite well at the beginning, but after 1 km it loses power. the voltage on the battery is fine, which is causing a sharp do not know falling power! :(

Hello, please excuse the poor subject line. I recently bought a Spintend ESC for use in my e.bike project and Im also very much new to this field. I ran into an issue pretty much immediately; the ADC-adapter takes up the one and only AD socket, which I had intended for the bluetooth module. The thing is that Im unable to perform an initial setup of the throttle and brake without using the app and the BT module.

Hello there,

i just destroyed mechanically my USB Port and I see no chance to repair it. How can I still connect my computer to the ESC?
I have a Flipsky Bluetooth Adapter connected to the COMM port of the ESC and can connect via smartphone but not via VESC Tools on the computer. Why not?
Any other possibilities? The COMM-Port directly or the CAN-Port? Which adapters do I need?

Any help appreciated, Thanks, Joerg
