Abstract

The Servo Drive with Incremental Encoder for PMSM FOC Evaluation, or Servo Drive with QEP for short, is a framework to develop, and experiment with, field-oriented control (FOC) of permanent magnet synchronous motors (PMSM). In this framework, the PMSM's position is sensed by an incremental encoder (QEP). The framework runs on a low-cost F29H85x-based LaunchPad plus a three-phase inverter evaluation module (EVM). Testing can be performed with a low-voltage PMSM.
