Design and Development of Low Torque Ripple Variable-Speed Drive System With Six-Phase Switched Reluctance Motors [PDF]
, 2018 Switched reluctance motor (SRM) drives conventionally use current control techniques at low speed and voltage control techniques at high speed. However, these conventional methods usually fail to restrain the torque ripple, which is normally associated ...

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

An Improved DITC Control Method Based on Turn-On Angle Optimization
CES Transactions on Electrical Machines and Systems, 2023 Switched reluctance motor (SRM) usually adopts Direct Instantaneous Torque Control (DITC) to suppress torque ripple. However, due to the fixed turn-on angle and the control mode of the two-phase exchange region, the conventional DITC control method has ...

Detection of inter-turn faults in multi-phase ferrite-PM assisted synchronous reluctance machine [PDF]
, 2019 Inter-turn winding faults in five-phase ferrite-permanent magnet-assisted synchronous reluctance motors (fPMa-SynRMs) can lead to catastrophic consequences if not detected in a timely manner, since they can quickly progress into more severe short-circuit

Noncontact electrical resistivity measurement technique for molten metals [PDF]
, 1998 A noncontact technique of measuring the changes in electrical conductivity (or resistivity) of conducting liquids is reported. The technique is based on a conducting drop that is levitated by the high-temperature electrostatic levitator in a high vacuum.
