SH2/2A Family: Sensorless Vector Control of Three-Phase Permanent Magnet Synchronous Motors
This application note presents Renesas' sensorless vector control solution based on the SH2-7086 microcontroller (MCU), which is part of Renesas' the SH2/2A Family, to enable high performance and cost effective control for permanent magnetic synchronous motors (PMSM). It describes the implementation hardware platform, the SH7086 MCU, software design, and sensorless vector control theory. Additionally, the document explains specifically how to modify the solution for different motors and applications. An example of parameter tuning is given.
