MCUXpresso SDK Field-Oriented Control of 3-Phase PMSM and BLDC Motors

Introduction

This document serves as a comprehensive user guide for implementing motor-control software for 3-phase Permanent Magnet Synchronous Motors (PMSM) and Brushless DC (BLDC) Motors. It leverages NXP's MCUXpresso SDK and the MC56F81000-EVK development platform, along with the FRDM-MC-LVPMSM platform.

The guide covers essential aspects including hardware setup, detailed processor features, peripheral configurations, and the overall project structure necessary for developing and testing motor control applications. It provides insights into the MC56F81xxx family of Digital Signal Controllers (DSC), highlighting their efficiency and suitability for power conversion and motor control.

Key topics include motor parameter identification, algorithm tuning, and the use of tools like FreeMASTER for debugging and diagnostics. The document also details the hardware timing and synchronization crucial for motor control applications, as well as CPU load and memory usage analysis.
