THEORETICAL AND EXPERIMENTAL INVESTIGATIONS OF THE CROSSMAGNETIZING PHENOMENON IN SATURATED SYNCHRONOUS MACHINES
… determining the various saturation factors of salient-pole synchronous machines, a method for calculating the open-circuit characteristic curves in the intermediate axes of these machines is developed. This method can also be applied in calculating the cross-magnetizing effect of the …

Advancement of a modular rotor permanent magnet flux switching machine for high torque performance
… PM excitation sources are on the stator, and the salient pole rotor is simple yet robust. Regrettably, salient rotor and stator of PMFSM with single tooth winding have inherited flux cancellation, flux leakage, high iron losses, high winding losses, and longer flux paths which reduced the torque …

Control of Pseudo-Sinusoidal Switched Reluctance Motor with Zero Torque Ripple and Damped Input Current Ripple
… traditional AC and DC motors due to the doubly salient pole structure and the highly non-linear coupling between torque, rotor position and phase current. As a result of the torque ripple on the shaft, unwilling large acoustic noises are generated. The large current ripple at the DC bus input …

Using Intrinsic 3rd Harmonics for Large Synchronous Generator Insulation Fault Condition Monitoring
… technique’s sensitivity to inter-turn faults in salient field poles, third harmonic current was injected into suspected poles, which showed significant overheating and potential inter-turn short circuits. Conventional voltage drop methods were compared with recurrent surge oscillograph results, …
