Analysis of Direct Torque Control Response to Stator and Rotor Faults in Permanent Magnet Synchronous Machines

open access: yesEnergies, 2023
Direct-torque-control-driven permanent magnet synchronous machines eliminate the need for a position sensor while providing improved torque dynamics. However, the structure, regulation principle and nature of compensation of hysteresis-based controllers ...

Analysis of the Saliency Ratio Effect on the Output Torque and the System Efficiency in IPM Drives

open access: yesSakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2021
Permanent magnet synchronous motors (PMSM) can be classified into two groups based on the rotor saliency structure as surface mounted permanent magnet synchronous motors (SPM) and interior mounted permanent magnet synchronous motors (IPM). Saliency ratio

Scaling laws for synchronous permanent magnet machines

open access: yes2015 Tenth International Conference on Ecological Vehicles and Renewable Energies (EVER), 2015
This paper defines the scaling laws for synchronous permanent magnet machines which include three separate procedures: rewinding, axial scaling, radial scaling. The derivation of scaling relations is based on the requirement that the magnetic fields in the scaled model should be the exact images of the fields in the referent model.

Design of Low-Cost Synchronous Machine to Prevent Demagnetization

open access: yesEnergies, 2020
The request for high efficiency motor paves the way for the replacement of induction motors with permanent magnet synchronous motors. Although the efficiency is increased, for medium and high power, the current ripple causes significant additional losses

SYNCHRONIZATION AND ANTI-SYNCHRONIZATION OF CHAOS IN PERMANENT MAGNET RELUCTANCE MACHINE

open access: yesFar East Journal of Dynamical Systems, 2007
In this paper, we investigate chaos synchronization and anti-synchronization between two coupled permanent magnet reluctance machines (PMSM) exhibiting chaotic behaviour. Nonlinear controllers derived from nonlinear control theory are designed for a drive-response PMSM system so that the response system synchronizes and anti-synchronizes with the drive
