$450 Mige Direct Drive Wheel using MMOS and AASD

50v is enough for full torque at low speed.
But actually the reaction of a big motor is bad, so the reaction must be enhanced by PID control.
Simply put,extra voltage is applied to enhance the reaction when increasing the torque.
Conventional direct drive wheels are 50v.
200v industrial driver have more additional voltage.
I am interested in how this affects performance.

hi, I had an M15015 engine, I got a problem with the engine vibrations when I put the STM32 to 16.8khz, when I put it at 4 khz, the vibrations decrease, but the engine screaming, someone would know to tell me where this problem, thank you very much

16.8khz if you don't use dac.
Try lowering pn190.

thanks for your answer, pn190. I've got it tight. I think if I lower it or raise it right. It starts to turn left, I got it to -90, if I can turn up video

it's normal that you hear more noise at 4khz.

i get the same harmonics on 4khz with my motor. you should use 16khz + pn190 between -100/-80 if you don't have a DAC board.

the video is with dac pn190 -90 at 16khz, I don't understand how the engine vibrates so much

probably due to the different inductance this motor has. it has much higher inductance than 130st-m10010 so it will behave differently on same pwm frequency. pn190 won't do anything about the noise it just helps getting rid of the left-right wiggle when the motor is "idle".

i have it set up according to the engine manual with PN001 to 24, would you have to change?

Use DAC or cr low-pass filter
You need to smooth pwm.
If not, increase Pn188.

forgive my ignorance, how does the cr low pass filter fit?

thanks when I have some material I'll try

what Pn188 have you got it set to? but yeah try that filter also

Pn188 to 159

Does the vibration you mentioned at first mean this noise?
Doesn't it change even if Pn188 is increased?
Is there noise in the jog test?

there noise in the jog test perfect, with parameter No 188 I don't notice change, this afternoon I'm going to try changing the cable to stm32 i play a little with the parameters

@vicborder
Do a jog test without connecting stm32.
Is there noise?

i don't know if it's a problem, but just connecting CN2 pin 9,6,10,13,20,18,15, with the pn190 parameter, the engine starts to turn right just by when I put it to -90

i mean, that empowering just the -E-Stop, engine turns only to the right and to stop the movement I have to put PN190 to -90, is that normal? thank you

slightly off topic, but still to do with the setup. I know people use the g25/27 pedals/shifter to plugin to the board, but has anyone plugged in diy or other brand of pedals? Obviously the pedals are just 3 pots and this should be east, but i know the shifter uses two pots to determine what gear and a switch for reverse gear selection.
