hello all! Recently, I’ve built my longboard using these components: sk3 6374 168kv motor Turnigy 150A ESC rocksta transmitter/receiver 6s6p battery from salvaged laptop batteries diy deck in a shape of vanguard, caliber 2 trucks, ogangatang kegel wheels 16:36 pulleys on 15mm belt
this setup is quite good at higher speeds (top ±22kph), but when I need to go slower, sometimes the motor just freaks up - lots of weird sounds come out. At the same time, I have to push once to get it moving, I can’t accelerate from zero. I can’t find out whether this is a problem of esc setting, motor kV, gearing ratio, or too shitty batteries. here are setting of ESC: http://imgur.com/a/QlUaI (to be honest, I understand nothing here)
I think this is not a problem of battery, because the same happened with 12v lead acid, maybe just more aggressively due to low voltage. Also probably not a problem of gearing ratio, because if I changed it for more torque, I’ll go slower. I don’t want that to happen.
at low speeds, it just feels like the ESC changes polarity in motor too quickly, which means it is unable to rotate enough to be “caught” by next winding.
