the normal speed of my motor is 40 000 N. i tried to run it with the RT1050 foc demo , it can run at the speed of about 4000 N. I check the MCAD options ,the limitation is 4399 as the attatchments .
1,is the anyway to disable the limitation?
2, i check the m1_pmsm_appconfig.h file can i change the M1_N_MAX symbol to 10000 or bigger to get the faster speed？
You can modify the parameters of MCAT according to your motor if you modify M1_params.txt in the below path of the SDK package.
Hope it helps!
thanks，i will try it， I got "phase error" while i tred to run a bldc witch runs at above 35000 N，i measure the PWM IN wave for gd3000 and PWM out from GD3000 ，i fount the out put from GD3000 for upper mosfet is wrong which combines the PWM for lower MOSFET，it is real strange. for detail ，please see the atatchment.
