A Low Coupling Fault Tolerant PMA-SynRM With Mixed-Pitch Segregated Windings

A Magnetic-Geared Machine With Improved Magnetic Circuit Symmetry for Hybrid Electric Vehicle Applications

“…To alleviate the asymmetrical magnetic circuit issue, the filtering property of the armature winding should be improved. At present, novel winding layouts have been employed to reduce the armature magnetomotive force (MMF) harmonics, such as short-pitched windings, multilayer structure, stator shifting technique, and unequal turns per coil [21]- [24]. The implementation of these winding layouts to MGMs is literally absent while this paper aims to analyze the potential of MGM with novel winding layouts.…”

Research on Inter-Turn Short-Circuit Fault Diagnosis Method Based on High Frequency Voltage Residual for PMSM

“…The short-circuit current will generate a considerable amount of heat to further damage the winding insulation, causing a vicious cycle until completely breakdown. To solve the problem, prominently efforts have been invested in fault-tolerant machine design [8]- [10], fault-tolerant strategies [11], [12] and fault detection methods [13]- [18]. At present, it is still an irreplaceable protective measure to adopt an appropriate fault diagnosis method to alarm faults and take mitigation measures.…”

Design, analysis, and application of field-modulated machines with direct-drive features for automated ground vehicles

“…At present, many novel winding layouts have been employed to reduce the armature magnetomotive force (MMF) harmonics, such as short-pitched windings, multilayer structure, stator shifting technique, and unequal turns per coil [128]- [131]. The application of these winding layouts to FMMs is literally absent while this section aims to analyze the potential of FMM with novel winding layouts.…”
