About BLDC motor solution

[TGoto.1]

There are two ways of BLDC motor solution. The one of solutions is EVSPIN32F0601S3 and the other is EVSPIN32F0601S1. I want to drive BLDC motor with sensor less. Which solution is match the goal? The motor specification is 100V D.C. 1A 100W.

Hello @TGoto.1​ and welcome to the ST Community.

Both solution you mentioned are based on STSPIN32F0601 System-In-Package and fit your motor specification.

The main difference is in the shunt sensing topology:

• EVSPIN32F0601S1 has a single-shunt sensing topology. Both the field-oriented control (FOC) and sensored or sensorless 6‑step control can be implemented.
• EVSPIN32F0601S3 has a three-shunt sensing topology. The field-oriented control (FOC), either sensored or sensorless, can be implemented.

You can choose the board according to the driving method (FOC or 6-step) and shunt topology (single or three).
