If Motor Profiler will open source?

[gtop.1]

I often use Motor Profiler to identify motors.But it is not good.

Sometimes my motor cannot be recognized when using 48V and I have to reduce the supply voltage to 36V.

Here I would like to ask whether it will be open sourced. I want to understand the principle of identifying the motor and improve it.

Hello @gtop.1 

To answer your main question, there are currently no plans to make the Profiler opensource. to let me better understand your problem to help you find a solution: Can you tell me which version of the MCSDK you are using? and which power board and control board do you use ?
Thank you

Hello.

I use 5.Y.4 MCSDK and NUCLEO-F302R8+X-NUCLEO-IHM08M1 3Sh，with 48V 471W pmsm motor. The motor keeps turning and cannot identify the Ke.

Can you try with the new version of MCSDK 6.2, and tell me if it works better. To use the profiler on 6.2 you must generate a profiler firmware, for this please follow the MCSDK documentation.

Yes,it works better. It can work in 48V now.:grinning_face::grinning_face:

I want to kown how to calculate the Ke.

I refer here：https://wiki.stmicroelectronics.cn/stm32mcu/wiki/STM32MotorControl:How_To_manually_configure_the_motor_parameters

Below is the profiler's result. Ke=9.59 Vrms/kRPM.

Below is my owm test.

Vpp=13.6v，pole pairs=5，fbemf=83.33Hz. Ke=(13.6*5*1000)/(2√2*83.33*60)=4.8085 Vrms/kRPM.

I wonder if I chose the wrong frequency？Is it between point A and point B or pointA and pointC?Thanks.
