Dear @PBoni.1304 and @Vdsfg.1
There is now in the last SDK version a demonstration firmware example projects for ACIM showing how the STM32 MC SDK can be used to drive an asynchronous induction motor (ACIM) in field-oriented control (FOC) using a sensorless state observer algorithm to estimate the electrical and mechanical speed and position of the rotor and the rotor flux, or in V/F open-loop sensorless mode.
Please have a look on our STM32 Motor Control Knowledge database here: https://wiki.st.com/stm32mcu/wiki/STM32MotorControl:SDK_AC_induction_motor .
Best regards
