RDDSCPMSMVC: PMSM Vector Control with Single-Shunt Current-Sensing Reference Design Using MC56F8013/23

Overview

This application creates a vector control PMSM drive with optional speed closed-loop using a quadrature encoder, and serves as an example of a PMSM vector control system design based on the cost-effective 32-MIPS NXP® digital signal controller MC56F80XX.

  • Dedicated algorithms such as transformations, PI controllers and space vector modulation, are implemented using NXP’s Motor Control Library
  • This cost-effective and highly reliable solution minimizes system cost, as the algorithm implements a single shunt current sensing, reducing 3 current sensors to one
  • The reference manual provides a detailed description of the application, including the design of the hardware and the software

Features

  • Designed to fit into consumer and industrial applications
  • Uses 56F8013 or 56F8023 32 MIPS Digital Signal Controller
  • Running on a 3-phase High Voltage Power Stage
  • Vector control of PMSM using theQuadrature Encoder as a position sensor
  • Control technique incorporates:
    • Vector control with speed closed-loop with position encoder
    • Rotation in both direction
    • Start from any motor position with rotor alignment
    • 4-quadrant operation
    • Reconstruction of three-phase motor currents from DC-Bus shunt resistor
    • Wide speed range
  • FreeMASTER Control Interface
  • Fault protection - overcurrent, overvoltage, undervoltage
