In this fifth lecture of the motor control course we discuss about how can we read the hall sensors to obtain the rotor position in order to know how to apply the correct voltage sequence to the motor phases. 

 

Main topics:

    - How Hall sensors works;

    - How to define a commutation sector;

    - How to identify the hall sensors and hall sensors alignment;

    - How to build applications to read the hall sensors via GPIO and eTIMER Capture;

    - How to implement an enhancement to read the rotor initial position to allow the startup from any position;

 

Objectives:

    - Understand how hall sensors works;

    - Implement from scratch Simulink models for GPIO and eTIMER for MPC5744P;

    - Setup FreeMASTER for real time data visualization;
