Control and synchronization of two BLDC motors

[denisdenk]

Good day!

Please tell me where I could see the connection diagram for controlling two brushless motors using STSPIN32G4? I couldn't find any information on the site. I saw a video on youtube https://www.youtube.com/watch?v=E8NkogGR--s 

But i couldn't find info and schematics or developer board for two BLDC motors

Thank you!

Hello denisdenk,

Attached you can find an example of how the STSPIN32G4 can be wired with the STDRIVE101 to drive two brushless motors.

The key point is to use Advanced Timer TIM8 to control STDRIVE101 inputs.

The diagram shows the mapping for both 3 PWM driving method (i.e. dead time generated by STDRIVE101) and complementary PWM using PB3/PB4/PB5 for the low side MOSFETs driving.

We are working on the publication of a dedicated reference design. Stay tuned!

Kind Regards

Enrico
