Hello,I need you help . For implementing sensorless control of a PMSM motor using the STEVAL-IPM30B and STM32F407, how should their pins be connected? Should the control board's required feedback for voltage and current be directly connected from the given sensing points?

Hello @Wei1,

Firstly, sorry for the delay in replying to your post.
If your point is still pertinent, STEVAL-IPM30B Phase_A/_B/_C are connected to PMSM motor 3 phases.
Control board's required feedback: Voltage via STEVAL-IPM30B J2 PIN14, and current feedback via J2 PIN15/17/19.

If you agree with the answer, please accept it by clicking on 'Accept as solution'.
Best regards.
