Item A NEW INCREMENTAL AXIAL FLUX PERMANENT MAGNET SYNCHRONOUS GENERATOR GENERATING ENERGY BASED ON MAGNITUDE OF EXTERNAL TORQUE(2022-02-25) Mohammed, Esmail; İrfanoḡlu, Bülent; Nazlıbilek, SedatNowadays the global warming phenomenon is growing mainly due to conventional energy production and increasing energy demand. Renewable energy sources such as; the wind, sun, sea, and rivers produce green energy to reduce this adverse phenomenon and contributes to the energy production. Recently, alternative energy sources for generating electric power has become popular. Several types of machinery is used to generate electrical energy. The majority of these systems use gearboxes to regulate the generated power. However, the gearboxes attached to the wind turbine through the generator have some disadvantages. They require periodic maintenance and suffer from frequent disorders. They may cause some loss of energy due to friction in metal parts resulting in poor efficiency. Furthermore they are not reliable machines, and they are heavy. It is difficult to carry out their maintenance periodically. In this study, three phase multi stages axial flux permanent magnet coreless generator has been designed, modelled, analysed, and controlled to avoid these disadvantages. The goal was to design and control the generator that would utilize a direct connection without a gearbox. The electronic controller is aimed at replacing the bulky gearbox. This has several advantages such as it provides energy at low wind speeds, results in decrease in the system size, and the weight is also reduced. In addition to these advantages the system efficiency and reliability is increased.
