Magnetic equivalent circuit and finite element modelling of anisotropic rotor axial flux permanent magnet synchronous motors with fractional slot distributed winding

open access: yesIET Electric Power Applications, 2023
Axial flux motors have been in the focus of many research work due to their promising properties when compared to conventional radial flux machines. Axial flux permanent magnet synchronous motors (AFPMSM) studied in the literature were mostly limited to ...

Euler-Lagrange models with complex currents of three-phase electrical machines and observability issues [PDF]

open access: yes, 2009
A new Lagrangian formulation with complex currents is developed and yields a direct and simple method for modeling three-phase permanent-magnet and induction machines. The Lagrangian is the sum a mechanical one and of a magnetic one.

Energy-based modeling of electric motors [PDF]

open access: yes, 2014
We propose a new approach to model electrical machines based on energy considerations and construction symmetries of the motor. We detail the approach on the Permanent-Magnet Synchronous Motor and show that it can be extended to Synchronous Reluctance ...

Permanent magnet vernier machine: a review

open access: yesIET Electric Power Applications, 2018
Permanent magnet vernier machines (PMVMs) gained a lot of interest over the past couple of decades. This is mainly due to their high torque density enabled by the magnetic gearing effect. This study will provide a thorough review of recent advances in PMVMs.

Uncontrolled generation in interior permanent magnet machines [PDF]

open access: yesConference Record of the 2004 IEEE Industry Applications Conference, 2004. 39th IAS Annual Meeting., 2004
The movement toward higher power automotive electrical systems has spurred research into low-cost alternators capable of operating over a wide constant-power speed range. A promising candidate for this application is a specially designed interior permanent-magnet (IPM) machine operating in uncontrolled generation (UCG).

Comparitive study of the influence of harmonic voltage distortion on the efficiency of induction machines versus line start permanent magnet machines [PDF]

open access: yes, 2012
Induction machines have nearly reached their maximal efficiency. In order to further increase the efficiency the use of permanent magnets in combination with the robust design of the induction machine is being extensively researched. These so-called line
