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.

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 ...

Synchronous Reluctance Motor Parameter and State Estimation Using Extended Kalman Filter and Current Derivative Measurement

open access: yesIEEE transactions on industrial electronics (1982. Print), 2021
The synchronous reluctance motor is becoming a very attractive alternative to the ac induction machine. This is due to the lack of rare-earth metals in their construction and a higher efficiency, which was brought about by recent progress in rotor design.

COMPARATIVE ANALYSIS OF SYNCHRONOUS MOTORS

open access: yesJournal of Energy Technology, 2023
This paper compares the parameters, steady-state and transient characteristics of two different types of synchronous motors (SM) – a motor with surface mounted magnets on the rotor, and a motor with embedded magnets and squirrel cage winding, widely known as a line-start synchronous motor.
