This paper presents a research regarding a special design for a micro-wind turbine that drives a permanent magnet generator with two rotors that spin in opposite directions and recovering the energy by intermediate of brushes-rings system. The aim of this study is to develop and prove the functionality of a two rotors counter rotating permanent magnet generator by comparative results between the finite...
This paper approaches the design using two optimization techniques for a permanent magnet generator used in a micro-wind turbine, with a major importance on the overall performances of the energy conversion system. The proposed micro-wind generator has two armatures and both are rotating in opposite directions.
This paper approaches the electromagnetic design and finite-element analysis of a radial flux NdFeB permanent magnet synchronous machine for use as direct-driven generator with low speed micro-wind turbines. The design evaluation of the radial-flux spoke-type permanent magnet (RFPM) generator, based on 2-D and 3-D finite element field analysis, proves that this topology represents a good-performance...
Technology is rapidly changing and the automotive world is constantly improving. One of the challenges for automotive industry is to develop the completely autonomous car. Even if proven feasible, the autonomous driving car is still an important research subject due to systems complexity, costs and legislation. The paper describes an experimental car that Renault is actively developing in partnership...
This paper investigates two topologies of ferrite-permanent-magnet synchronous machines for use as direct-driven generators in micro-wind power applications, i.e. the axial-flux double-sided inner-stator permanent-magnet (AF-PM) generator and the radial-flux spoke-type interior-permanent-magnet (RF-IPM) generator. The comparative design analysis of AF-PM and RF-IPM micro-wind generators based on finite-element...
This paper approaches the electromagnetic design and finite-element analysis of an axial-flux permanent-magnet (AFPM) synchronous generator for small-scale wind turbines. The study is conducted to find a good-performance and cost-effective electric generator topology for micro-wind power application. The proposed double-sided two-stators-one-rotor AFPM synchronous generator with non-overlapping concentrated...
This paper proposes an innovative topology for double-sided inner-stator axial-flux permanent-magnet (AFPM) machine for use as direct-driven generator with low-speed micro-wind turbines. The design evaluation of the new AFPM wind generator, based on 3-D finite-element field analysis, proves that the ironless stator with non-overlapping concentrated winding, sandwiched between two opposing steel-rotor...
This paper presents a comparative study between the axial-flux and radial-flux permanent-magnet synchronous generators for a 3 kW wind turbine application. This study emphasizes the most cost-effective solution to be implemented by the industrial partner. There are three constructive types of electric generators considered in this work. All are based on permanent-magnet synchronous generators (PMSGs),...
