    A warning about KO controllers

    In China, I think the controller with the highest playability is mobipus, followed by the fardriver, their software is doing well, it is always updated, and there are more parameters to adjust.

    A warning about KO controllers

    This is a cheap Chinese product. It looks like the controller software of Nanjing FarDriver was copied, and as far as I know, the HEX code of Nanjing FarDriver was stolen by some people and used to produce controllers of other brands

    GaN and IMS MESC controller boards

    Received, thanks, I will test them on my hardware, my hardware uses an external opamp INA181A1, I need to reconfigure the CUBEMX. I saw the schematic diagram of the new version released by you. After the phase voltage is sampled, a 68nF capacitor is added. Will this affect the collected phase...

    GaN and IMS MESC controller boards

    Please check the SMS on the site, I have sent the reference project and hope it can be helpful to you. This ADC sampling waveform is relatively smooth because my low-pass filter circuit cutoff frequency is too low, now I have corrected them, the cutoff frequency is about 159KHZ.

    GaN and IMS MESC controller boards

    Thank you mxlemming, I changed some CUBEMX configurations so that the ADC can collect current normally (I think it may have been configured correctly), now I use sensorless operation, and I will find that the waveform of the variable FOC_ANGLE is not perfect sawtooth, there will be Some curls...

    GaN and IMS MESC controller boards

    Compared with the 303CB version hardware you announced in the past, the phase voltage is only divided by resistors without connecting capacitors. I built a 303 version of the hardware, using an INA181, but it doesn't work very well, the FOC_ANGLE is not very continuous, causing difficulty in...

    GaN and IMS MESC controller boards

    Hello mxlemming, the previous version did not use the phase voltage filter, but the new version uses it, the cutoff frequency is still relatively low, will it cause a large amplitude and phase difference? Is compensation done in software?

    BYD25KW BSG motor

    I'm from China, and I found this on a second-hand item trading platform in China, belt-Drive Starter Generator for BYD Hybrid.Its maximum power is 30KW, It weighs only 13KG.but the operating voltage is very high, reaching 600V.I want to wrap the coil again and change its operating voltage at 80V...
