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:

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. If you use the same motor, please connect the brown, grey and yellow phases as shown in the picturerespectively, otherwise your motor doesn't run.
