In this paper, a hexagonal magnet shape is proposed to have an arc profile capable of reducing torque ripples resulting from cogging in single-sided axial flux permanent (AFPM) machine. The arc-shaped increases the air-gap length effectively and makes more sinusoidal, which decreases density hence causes reduction torque. Cogging basic source vibration, along with noise PM machines, since it ma...

Hematite (α-Fe2O3) nanoparticle was synthesized using organometallic compound - ferrocene carboxaldehyde through solventless solid state thermal decomposition technique. The crystal structure, magnetic and morphological properties of the decomposed material were studied using powder X-ray diffraction (XRD), superconducting quantum interference device (SQUID) magnetometry, ...

Small angle x-ray analyses show that the shear-induced hexagonal perforated layer phase in a poly(ethylene oxide)- b-polystyrene diblock copolymer consists of trigonal (R3;m) twins and a hexagonal (P6(3)/mmc) structure, with trigonal twins being majority components. Transmission electron microscopy reveals that the hexagonal structure is generated through sequential intrinsic stacking faults on...

This paper introduces hexagonal shape sensors that is a meander and mesh type. Modelling, simulation and development of Hexagonal Sensor and the results are discussed in this paper. The characteristics of hexagonal spiral inductor and interdigital capacitor are determined. The hexagonal spiral inductor is a new electronic sensor that can be used for various measurements that produces magnetic f...

As part of the work, hexagonal structure B19 type metals as hydrogen sorbents will be considered. That is, crystal lattices are considered, where atoms impurities (hydrogen) introduced into interstices metal. To do this, we present an image itself. In this solubility in was studied using configuration method, and dependence on composition alloy temperature found substitution nodes interstices. ...

In this paper, a Y-shaped power splitter based on a two dimensional photonic crystal (PhC) for TE modes is designed and optimized. A triangular lattice of air holes is used for Y-shaped power divider. For analyzing these structures, plane wave expansion (PWE) and finite difference time domain (FDTD) methods are used. The simulation results show that more than 98% of the input power is transmitt...

In our present work undoped CdS and Cu doped CdS thin films were deposited on glass substrate by chemical bath method. XRD analysis of the as-prepared sample indicated CdS:Cu nanorods to be mixture of two phases namely hexagonal and cubic. It has been observed that one particular plane (100) has preferentially grown as the maximum intense peak whereas the other two planes (101) and (102) have d...
