The schematic of a PMSM drive using a DTC-based speed loop PDFF controller is shown in Fig. 1. This DTC scheme is implemented in stator flux frame, which requires knowledge of stator flux in ...

Researchers at Sichuan University have proposed a four-level modulation strategy for dual three-phase open-winding PMSM drives, offering higher efficiency and lower current harmonic in such ...

This article presents the vector control of a 3-phase PMSM using the ZNEO Z16FMC microcontroller. It discusses the implementation of field oriented control scheme for PMSM, and summarizes the ...

Editor's note: This article was first featured in the February 2003 issue of EC&M. It has been updated to reflect newer power quality instruments and updated standards. Today, many facilities have ...

Variable speed drives (VSDs), sometimes also known as variable frequency drives, are electronic devices used to regulate the speed of an ac induction motor. Electric motors consume approximately 25% ...

The thyristor d.c. drive remains an important speed-controlled industrial drive, especially where the higher maintenance cost associated with the d.c. motor brushes (c.f. induction motor) is tolerable ...
