With a Few Mouse Clicks to an Efficient Motor Control Design

Focus:

Alternatives to hard-coded solutions, the XC878/886/888 MCUs from Infineon are 8-bit microcontrollers capable of implementing field oriented control (FOC) for brushless DC and permanent magnet synchronous motors. FOC enables improved efficiency and dynamic response and limits audible noise. After a brief discussion of the on-chip features that make these MCUs suitable for FOC, this article describes the Infineon software development tools that support and speed implementation of FOC. In particular, the article describes the features of the Digital Application virtual Engineer (DAvE) configuration tools. Details are provided on an auto-code generator called DAvE Drive version 2, which "shortens the evaluation time for motor control developers significantly as the motor control code can be generated via a GUI instead of handwriting some "thousands lines of code."

What you’ll learn:

• How to understand microcontroller-based design options for implementing field-oriented control in BLDC and PMSM motors
• How to understand what software development support is available for implementing FOC-based motor control using 8-bit MCUs
