Hello ST Community,
I am designing a residential pump driver product that requires a Variable Frequency Drive (VFD) to control a three-phase AC induction motor. I am using the STM32 Motor Control SDK as a reference, specifically the AC induction motor page.
https://wiki.stmicroelectronics.cn/stm32mcu/wiki/STM32MotorControl:SDK_AC_induction_motor
My goal is to find the most cost-effective STM32 MCU that can reliably implement this control. Is there a cheaper alternative to STM32G431RB? For example, can i use STM32F0 or G0 series?
Also is there any other reliable solutions except for MCSDK which may lead to this goal, meaning a lower BOM cost?
Is there any plan to add ACIM driver support in MCSDK V6.X in future?
Thank you for your time and expertise.
