X-CUBE-SPN7 motor control

[user-stm]

Dear all,

I am using the STM32 Nucleo pack with a F302R8 card, the IHM07M1 and the associated motor.

The library for motor control (6Step_Lib.c) of  X-CUBE-SPN7 only provides a few functions, for ex MC_StartMotor, MC_StopMotor() and MC_Set_Speed().

I would thus be interested to know how to control the motor given a specific angle as input : it seems that only using theses 3 functions won't be precise enough : for example if we use MC_Set_Speed() to set the speed at w degree per second, and if we want a rotation of theta degree, rotate the motor (at speed w) for theta/w second won't enable to target a precise angle.

Thanks for your help & time ! 🙂

Hello user-stm,

If you want to do position control, I recommend you to use the MCSDK 6.1.2. You might also want to switch to FOC instead of 6STEP (as its name indicate, you can only go through 6 positions aka a step equal 60° which is really not precise)
Please refer to our Motor Control Wiki for how to use the Motor Control Suite.
If you really need to use the X-CUBE-SPN7, you can still enable it via CubeMX once your project is generated by WorkBench.

Hope this will help,
Gaël A.

Hi, Gael A,

I am trying to develop a project with a BLDC motor and want to use X-CUBE-SPN7 but i don't know how can I start. Dou you know where can I find some examples to start a project from scratch with NUCLEO-F401RE, X-NUCLEO-IHM07M1? 

Thank you in advance,

Cristhian

Hello @cristhianchr ,

X-CUBE-SPN7 is Not Recommended for New Design. The recommended starting point to generate a project with NUCLEO-F401RE and X-NUCLEO-IHM07M1 is with the MCSDK 6.2.1 available here.

Regards

Cedric
