RX62T

Position Control of PMSM with Encoder

Introduction

This document presents RX62T position control with a permanent magnet synchronous motor, which has been

implemented on RX62T evaluation kit with hall sensors and encoder.

The document describes hardware platform, methodology of position control, control block diagram, software structure,

and flow chart of the position measurement and control.

The solution in application note has been implemented with RX62T evaluation kit and a 3-phase 8-pole 24V PMSM with

a 1000 line single–ended encoder.
