DRV on my Flipsky 4.12 is dead @seaborder will get me sorted out
I tested the MOSFETS resistances:
I have 38kOhm between the 3 phase wires to GND and VCC, the values are rising when waiting and leaving the measuring sticks on the connections.
Is that normal?
So, I stumped upon it while trying to read R and L from the motor and hall sensor measurements. Everything failed and there was the 3 times blinking of the red led. After typing faults in the terminal, I got something like DRV_ERROR.
Out of curiosity, why does the resistance sometimes increase, decrease slowly over time when measuring?
I noticed that on low speed my right motor gets “stuck” as if you hit a rock or something. The motor amps in that moment drop to 0 or even in the negative for a split second.
at the end of the video, right before i stop you can hear a knock. Thats when it happened. It happens on bench and with load. Cannot duplicate it manually. Sometimes it happens and sometimes it does not.
Resistance increases with heat as well the “thermal sensors” are just resistors with known resistance and when heated the increased resistance (or actually the voltage drop from an applied voltage across the resistive wire/element) is measured.
takes a bit between both detections. I Recorded and made the detection on the same phone.
video 2 coming in a sec. There the motor stop too with the problem i described before. A split second before the motors stop you can hear the knock again.
I bought this esc off local craigslist.
Do you guys know what pre-built board its off of?
typical chinese esc, 10s hub motor esc, push to start, auto shut off, only 25km/h max speed though
