In this study, we successfully fabricated Fe61Zr10Co5Mo7W2B15 and Ni61Nb19.2Ta19.8 amorphous fibers (AFs) using the melt-extraction method. This method ensured a rapid cooling, uniform quality, minimal defects, superior performance. Magnetic property analysis revealed that Fe-based AFs exhibited single-slope magnetization curve characteristic of paramagnetic or diamagnetic materials, while Ni-based displayed rectangular with low magnetic hysteresis, typical ferromagnetic materials. The axial...
The optimization of the high frequency giant magnetoimpedance (GMI) effect and its magnetic field sensitivity in melt-extracted Co69.25Fe4.25Si13B12.5Nb1 amorphous microwires was systematically studied through a multi-step Joule annealing (MSA) technique. surface morphology, microstructure, property, radio GMI response Co-rich were explored using techniques like microscopy, magneto-optical Kerr (MOKE) magnetometry, dependence wire's impedance (GMI). protocol begins with an initial dc current...
A hybrid strategy based on nonsingular fast terminal sliding mode control (NFTSMC) and direct instantaneous torque (DITC) is proposed for six-phase switched reluctance motors (SRMs) to reduce the ripple improve dynamic response. First, capability of DITC under high-speed conditions, an improved conduction in commutation region designed exploit phase generation potential minimize switching loss. In addition, there exists a contradiction between response chattering conventional NFTSMC. To...
In the context of applying direct torque control (DTC) to switched reluctance motors (SRMs), negative is generated track demanded torque, which reduces system efficiency. To reduce ripple and enhance output efficiency, this paper proposes an optimization strategy based on online adjustment sector positions for DTC method a six-phase SRM. First, by utilizing magnetic characteristics generation properties DTC, new voltage vector designed, phase commutation rules are reformulated occurrence...
