Cheaper STM32 Alternatives for VFD Control of AC Induction Motors

Amirmhz

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.
