System architecture

A generic motor control system can be schematized in three main blocks (see Figure 2:

"Overall system architecture"):



Control block - its main task is to accept user commands and drive a motor. The X-

NUCLEO-IHM07M1 is based on the STM32 Nucleo board, which provides all digital

signals to properly implement motor driver control.



Power block - it is based on three-phase inverter topology. The core of the power

block is the L6230 driver, which contains all the necessary active power and analog

components to perform low voltage PMSM motor control.



Motor - the X-NUCLEO-IHM07M1 is able to properly drive a low voltage BLDC/PMSM

motor.

Building the system

The X-NUCLEO-IHM07M1 expansion board is a complete hardware development platform

(Power block) for the STM32 Nucleo board, for evaluating a motor control solution for a

single BLDC/PMSM motor. For normal board operation, it must be connected to an STM32

Nucleo board (Control block) through the ST morpho connector, as shown in the image

below.
