Getting started with X-NUCLEO-IHM07M1

This example demonstrates how to use the X-NUCLEO-IHM07M1 component with one of the STM32 Nucleo-64 platforms and a three-phase brushless DC (BLDC) motor with Hall sensors.

HW prerequisites

  • X-NUCLEO-IHM07M1
  • STM32 Nucleo-64 board
  • external DC power supply
  • low voltage three-phase BLDC motor with Hall sensors

Configure the jumpers of your X-NUCLEO-IHM07M1 board as shown in the picture below: /media/uploads/avilei/x-nucleo-ihm07m1_jumpers.jpg

This example is based on the BLDCmotorDriver motor control library by the TVZ Mechatronics Team, University of Applied Sciences Zagreb, Professional Study in Mechatronics. The BLDCmotorDriver library is a simple implementation of the six-step algorithm and needs Hall sensors to estimate the correct timing for commutation. If you want to use sensor-less BLDC motors with X-NUCLEO-IHM07M1, you must use a different software package like X-CUBE-SPN7, based on STM32Cube.

The HelloWorld_IHM07M1 application has been tested with the Nanotec DF45M024053-A2 motor, a 24V three-phase brushless motor with Hall sensors: DF45M024053-A2. If you use a different motor, please be advised that you may need to tweak the configuration parameters for the BLDCmotorDriver library.

This application implements a temperature check to prevent overheating.

In the picture below you can see an example setup with the Nanotec DF45M024053-A2 motor and a 24V power supply. /media/uploads/avilei/setup.jpg If you use the same motor, please connect the brown, grey and yellow phases to the OUT1, OUT2 and OUT3 connectors of the X-NUCLEO-IHM07M1 board respectively. Then connect the blue, green, white, red and black wires for Hall sensors to the A, B, Z, 5V, GND connectors of the X-NUCLEO-IHM07M1 board respectively. If your motor is different, you must pay attention to connect the motor phases and Hall sensors pin in the correct order otherwise it won't spin.
