A novel field modulated magnetic gear (FMMG) with concentric configuration is proposed and introduced to the drive train for a wind turbine system, which eliminates the vibration, noise and lubrication problems of mechanical gearbox and avoids the size and weight issues of directly-driven wind turbines The efficiency and reliability are improved simultaneously. Based on the static field computations...
In this paper has been tried to optimize the solar energy in a new way according to the increasing importance of renewable energies and a sample biaxial sun tracker is built. There are three algorithms for tracking the Sun: first algorithm, move the plane in circular coordinates in the small ranges, then find the point with the best voltage for its field of work and oriented to that and then repeat...
Rotor-coupling-rotor system of marine power plant will temporarily install on the rigid foundation for the delivery inspection, all the dynamic parameters are always satisfied with the design requirements; However, once it is installed on the real flexible foundation, rotor vibration of wide variable rotate speed get complicate because of the coupling between misalignment of isolator and dynamic meshing...
