An optimization method with three objectives: total power loss, weight, and torque ripple, and with one constraint for a minimum acceptable value for the power factor, is described. The design examples are for a direct-drive generator rated at 3 MW and 15 rpm. . ption makes for the best modern wind turbine drive trains is still going strongly. In t ighted like mechanical structure, thermal behaviour and electromagnetic structure. In order to reduce the cogging torque and electromagnetic torque ripple components, the air core topology has. . Abstract— This paper presents a multi-objective design optimization for a novel direct-drive wind turbine gener-ator. The design considerations presented in this paper are rotor eccentricity, short circuit current estimation, voltage refl ction at generator terminals due to high frequency switching and forces during. . Subsequently, an in-depth internal modeling, focusing on the electromagnetic behavior of the designed generator, is executed using finite element analysis (FEA) through the Ansys Maxwell RMXpert software.

Scientists in China have developed a direct-drive photovoltaic air conditioning system that can store solar power through ice thermal storage. All electrical components are DC powered including DC Compressor, high-efficiency DC Fan Motors, DC Valves & Solenoids, etc. In AC/DC hybrid systems, the unit can operate on direct current (DC) from solar panels during the day and automatically switch to alternating current (AC) from the grid when solar energy isn't. . Solar-powered air conditioning relies on converting sunlight into usable energy with photovoltaic (PV) solar panels. Integrated view, solar energy central air conditioner has the advantage of energy conservation, obviously, but it is still at. .
