Controlling 3 BLDCs on a single board? Which MCU to choose?

[BCamp.2]

Hi all,

I need to control 3 BLDCs on one board. I found that in order to precisely control BLDCs, you need a board with special motor control timers. I have only been able to find boards with two of these timers (Example NUCLEO-H745ZI-Q) but I need one with THREE. Thank you in advance.

Hello @BCamp.2​ and welcome to the Community 🙂;

A similar question is already asked here.

There are MCUs having 3 advanced control timers like STM32F303xD/xE, STM32F398VE,  STM32G474xB/xC/xE, STM32G473xB/xC/xE, STM32G484xE, STM32G483xE, STM32G491xC/xE and STM32G4A1xE MCUs.

For more explanation please refer to AN4013 "STM32 cross-series timer overview" and precisely Using the break function with other MCU resources Section.
