Hi all, Is there any C-code example available for implementing the V/Hz control algorithm on ARM Cortex-M4F MCU. Any help or guidance I will appreciate! Regards, Max

V/Hz control must be implemented for 3-phase induction motors.

Operating frequency range: 0 - 60Hz.

Input phase voltage: 400V.

Dear @Community member​ 

There is now in the last SDK version 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
