Permanent magnet synchronous generators (PMSG) have a huge potential for direct-drive wind power applications. Therefore, optimal design of these generators is necessary to maximize their efficiency and to reduce their manufacturing cost and total volume. In this paper, an optimal design of a six-phase 3.5 KW direct-drive PMSG to generate electricity for domestic needs is performed. The aim of ...

The design of a direct carbon fuel cell (DCFC) for continuous operation was successfully executed and is presented in this study. Petroleum coke, an abundant source Canada, used as pneumatically supplied to the anode side cell. open circuit voltage (OCV) reached 1.1 V generated power density 28 mW/cm2 at 700 °C 85 850 °C. After about 180 h cell's performance declined, due loss electrolyte. In n...

the following study aims to present an innovative approach for design. participatory design is the model of direct involvement of different social groups in the design from functional tools to environments, social institutions and businesses. diverse collection of practices has been developed to support this direct involvement by participatory design. people are invited to participate during di...
