Development of Dual Rotor Flux Switching Generator
Project Area of Specialization Electrical/Electronic EngineeringProject SummaryWind Energy is the most abundant form renewable energy resource to cope up with ever increasing energy demands in future. Wind Generator do not release any emissions that can pollute the environment. Designing an efficient and cost-effective wind power generators are a great matter of interest nowadays. Flux-switching machines are brushless machines having a dual structure the stator has excitation sources such as permanent magnets (PMs) and/or field-excited windings, as well as armature windings, while the rotor has no magnets or windings. High torque (power) density, great torque output capability, and high efficiency are all advantages of flux-switching machines. A new three-phase flux switching generator (FSG) aimed primarily at variable-speed low-power wind turbines. This generator's magnet-free structure decreases machine cost while also high flux controllability. Non-overlapped concentrated windings has to be cleverly incorporated into the dual-rotor middle-stator construction to shorten the field and armature end-windings. In order to generate maximum EMF and minimum cogging torque, a parametric evaluation of both stator and rotor pole arcs will be carried out. The performance of the final design will be evaluate using the finite element approach. Finally, a prototype has to be built and test to demonstrate its viability for wind energy systemsWind Energy is the most abundant form renewable energy resource to cope up with ever increasing energy demands in future.
