Zubax Myxa vs ESC32v3 with Tarot MT4008 motor

Hi Venkatesh,
First of all, I recommend to read this topic and check if Myxa is properly parametrized. For example, if you performed motor identification without a propeller. And I also recommend these parameters (they don’t have a big influence on power consumption, but increase stability) to set these values:

  • m.current_ctl_bw = 0.07 [unitless ratio]
  • o.ekf.q_eangvel = 300000 [(radian/second)^2]
  • o.ekf.q_id = 10000 [ampere^2]
  • o.ekf.q_iq = 100000 [ampere^2]
  • m.voltage_ramp = 26 [volt/second]
    After Motor Identification procedure these parameters should be roughly:
  • m.phi_milliweber = 1.45
  • m.ld_microhenry = 37.8
  • m.lq_microhenry = 37.8
  • m.rs_ohm = 0.096
    You also should check if you properly set up your testbench. It might be not calibrated. How much power consumption on your stand differs? It also could depend on the particular motor bandle. I’m not sure, that they have absolutely same characteristics.
