Al giorno d'oggi, il fabbisogno di risorse energetiche sta aumentando a un ritmo molto pi rapido. Dobbiamo capitalizzare tutte le opzioni disponibili per soddisfare tutte le nostre esigenze con facilit . Nel sistema di generazione dell'energia eolica, finora quasi tutti i sistemi utilizzano un generatore radiale con un singolo rotore e un singolo statore. Tuttavia, molte ricerche hanno mostrato un nuovo concetto per il generatore utilizzato nelle turbine eoliche: l'uso di un doppio rotore che presenta molti vantaggi rispetto al tradizionale rotore singolo. Questo libro presenta la tecnologia della macchina a flusso assiale che consiste in uno statore e due rotori. Lo statore si trova al centro dei due rotori ed scanalato su entrambi i lati.

This book presents the comprehensive design, development, and experimental validation of a high-efficiency two-rotor axial flux permanent magnet (AFPM) generator optimized for wind energy systems. The proposed generator features a dual-rotor, single-stator configuration with surface-mounted permanent magnets and concentrated windings, aimed at achieving high torque density and compact structure ideal for direct-drive wind turbine applications. A systematic design approach was employed, encompassing electromagnetic, thermal, and mechanical aspects. Analytical modeling and mathematical formulations were developed to determine key parameters such as magnetic flux density, torque output, back EMF, and losses. The design was further refined using finite element analysis (FEA) to optimize air gap flux distribution, minimize cogging torque, and ensure structural integrity under operational stresses.

One of the primary needs for socio-economic development in any nation in the world is the provision of reliable electricity supply system. This work is an experimental study of 1.1KW, 230V single phase Hybrid wind-solar system. This project was carried out at M/s Shree Enterprises, Ahmednagar. In this project, hybrid system technology was used with Hybrid Solar-Wind Power System that harnesses the renewable energies in sun and wind to generate the electricity. Here electric DC energies produced from photovoltaic and wind turbine system are transported to the load centre. Complete hourly data of output from solar system and wind generator is collected for 91 days during Oct.2013 to Dec.2013. The analysis of this data using weibull distribution is done to obtain the average power from the hybrid the results showed that development of hybrid wind -solar system for off grid communities will go a long way to improve socio- economy lives of people. One of the driving forces for social and economic development and a basic demand of nations is energy. Most of the energy production methods are one-way, which requireschange of form for the energy.
