    vesc 75100 ESC Hardware and firmware open source

    The range of the shunt is about 160A. I think if it is set too high, it may not work normally. For example, the overcurrent protection will fail, or it is easy to trigger faults frequently, so it is limited to 120a.

    FLIPSKY new 20s 100A tiny controller (vesc based)

    The main difficulty lies in the configuration of this linux environment, which has cost me a lot of time.

    FLIPSKY new 20s 100A tiny controller (vesc based)

    This is also my negligence. When I sold this ESC, I thought that the other party was just an electric skateboarding player and just wanted to use this ESC, so I didn't actively provide the modified code. Later, he didn't ask me for the code, but I can guarantee to provide the source code when he...

    After all, this is the use of open source VESC, so there are no protection measures for the code

    Will this be enough to get more current out of the Flipsky 75100?

    I am the original author of 75100 hardware. Due to my personal reasons, the schematic has not been completed. At present, there are only PCB files and source code. This is the 75100 which I have been working on for the last year March. I have made two versions, one using stm32f405rgt6 and the...

    Current loop resonance in higher ERPM under Current Mode

    Hi, I control vesc using current mode,at a certain speed,the motor shook so badly that it couldn't accelerate. Load has a certain inertia. I adjust the Current KP KI to change the speed of the oscillation. It doesn't help much. Protection due to serious out-of-control of current. But duty...
