The high-speed generators offer superior power-to-volume ratio and highly compact structure comparing with their lower speed counterparts. These advantages make high-speed machines eligible for distributed generating application with microturbine that one of the distributed power generation that produced electric in the remote and disastrous zones where grid power is unavailable. To achieve hig...

The cosmic muon generator CMSCGEN is based on a parametrization of the differential muon flux at ground level, as obtained from the air shower simulation program CORSIKA. We present the underlying ansatz for this parameterization and provide an approximation of the momentum and angular distributions in terms of simple polynomials, in the momentum range 3− 3000GeV.

The higher specific torque and power density of a transverse flux permanent magnet (TFPM) machine in comparison to a conventional machine makes it a promising direct-driven wind turbine generator. The new topology presented in this paper is believed to have a better utilization of the available in the nacelle space. This would favor a reduced inactive weight of the generator and thus remove one...

Modern energy demands led the scientific community to renewable energy sources, such as ocean wave energy. The present work describes a model for a cost efficient rotary electrical generator, optimized for ocean wave energy conversion. The electrical power, supplied by low speed mechanical movement, requires the use of electrical machinery capable of generating high amounts of torque. Among the...

This paper presents the development of a framework used to optimize and experimentally validate a novel axial flux direct-drive (DD) permanent magnet generator (PMG) for the offshore wind turbine market. This technology aims to offer significant levelized cost of energy (LCoE) reductions via capital expenditure and operating expense (CAPEX and OPEX) savings – a key objective for the offshore in...

Problem Statement: Axial flux permanent magnet machines are regarded as compact high efficiency generators for micro-turbines employed in the distributed power generation systems. Highspeed rotor of the generator causes some designing and modeling problems. Sensitivity analysis tasks of the machine parameters are difficult and completely different in comparison with the problems associated with...

Renewable energy sources bring to fore the significance of power electronics and corresponding control. The topic of wind turbine fault-tolerant control has emerged as a promising line of research for improving their market competence.

The inverse magnetostrictive effect is an effective property for energy harvesting; the material needs to have large magnetostriction and ease of mass production. Fe-Co alloys being magnetostrictive materials have favorable characteristics which are high strength, ductility, and excellent workability, allowing easy fabrication of Fe-Co alloy fibers. In this study, we fabricated magnetostrictive...

Abstract: Axial flux permanent magnet generator (AFPMG) is can have one or two sided stator windings, meaning that the rotor disc of which the permanent magnet (PM) are mounted may be sandwiched in between two parallel stator discs. This paper deals with the development of AFPMG for a gearless wind energy system. This gives the axial air gap PM generator the potential for very high torque gener...
