Torque prediction using the flux-MMF diagram in AC, DC, and reluctance motors [PDF]

open access: yes, 1996
This paper uses the flux-MMF diagram to compare and contrast the torque production mechanism in seven common types of electric motor. The flux-MMF diagram is a generalized version of the flux-linkage versus current (ψ-i) diagram for switched-reluctance ...

Analysis on accuracy of rotor‐locked transient‐response‐based vibration model for switched reluctance machines

open access: yesIET Electric Power Applications, 2022
This paper investigates the accuracy of rotor‐locked transient‐response (RLTR)‐based vibration model for switched reluctance machines (SRM). RLTR is stator vibration stimulated by abrupt change of radial force when turning off one phase of SRM with rotor

Radial Force Density Calculation of Switched Reluctance Machines Using Reluctance Mesh-Based Magnetic Equivalent Circuit

open access: yesIEEE Open Journal of the Industrial Electronics Society, 2022
Acoustic noise and vibration is one of the shortcomings of a switched reluctance machine (SRM). Harmonics of the radial force waveform in the airgap excite the stator structure at different vibration modes with specific frequencies.
