A New Method for Computation of Axial Flux Permanent Magnet Synchronous Machine Inductances under Saturated Condition [PDF]

open access: yesJournal of Operation and Automation in Power Engineering, 2018
Accurate computing of the saturated inductances of Permanent Magnet Synchronous Machine (PMSM) is very important during the design process. In this paper, a new method is presented based on the B-H characteristic of the stator material and unsaturated ...

Prediction of the electromagnetic torque in synchronous machines through Maxwell stress harmonic filter (HFT) method [PDF]

open access: yes, 2006
For the calculation of torque in synchronous motors a local method is analysed, based on the Maxwell stress theory and the filtered contributions due to the harmonics of the magnetic vector potential in the motor air-gap.

Computation of the voltage-driven flux-MMF diagram for saturated PM brushless motors [PDF]

open access: yes, 2005
The flux-MMF diagram or "energy conversion loop" is a powerful tool for computing the average torque of saturated permanent-magnet brushless motors, especially when the assumptions underlying classical dq theory are violated, as they often are in modern ...

Analytical and numerical computation of air-gap magnetic fields in brushless motors with surface permanent magnets [PDF]

open access: yes, 2000
This paper extends the theory of the air-gap magnetic field in permanent-magnet (PM) brushless motors. Scalar and vector potential solutions to the field equations are brought together to unify many of the important practical methods already in use.
