Comparative Analysis of High Frequency Signal Injection Based Torque Estimation Methods for SPMSM, IPMSM and SynRM

open access: yesEnergies, 2020
Torque estimation in permanent magnet synchronous machines and synchronous reluctance machines is required in many applications. Torque produced by a permanent magnet synchronous machine depends on the permanent magnets’ flux and d q -axes ...

Permanent Magnet Reduction by Current Harmonics Injection for Surface Permanent Magnet Machines [PDF]

open access: yes2021 IEEE Workshop on Electrical Machines Design, Control and Diagnosis (WEMDCD), 2021
This paper presents the analysis of multi-harmonic current injection in multi-three phase surface permanent magnet (SPM) machines. An analytical model, extended to a generic harmonic order, is used to describe and determine the no load flux density, the back electromotive force (BEMF) and the electromagnetic torque produced.

An Improvement of Output Power in Doubly Salient Permanent Magnet Generator Using Pole Configuration Adjustment

open access: yesEnergies, 2020
The doubly salient permanent magnet (DSPM) machines are very attractive for low-speed power generation. In this work, we propose a design technique to improve the output power of the DSPM generator by an adjustment of pole configuration.

A new technique of cogging torque suppression in direct-drive permanent-magnet brushless machines [PDF]

open access: yes, 2010
In direct-drive electric propulsion systems, where there is no reduction gear to minimize and absorb the adverse effects of cogging torque generated by the permanent-magnet (PM) machine, minimization of cogging torque generation is of particular ...
