Diseño y simulación de un generador de imán permanente de rotor radial cónico de flujo axial de potencia 1.1kW para micro aerogeneradores

Resumen

In this study, design, design calculations and simulation of a permanent magnet generator, which includes two sections of radial
and axial flux, are discussed. The output power from the generator is 1.1 kilowatt. In the design of the generator, a cone-shaped
structure with a 90-degree cone angle of 45 degrees from the sides is used for the rotor. In order to compare the various structures
of the synchronous generator, and given that today, permanent magnet generators have been considered with regard to features
such as lower weight, higher yields and higher power density than other conventional generators. A finite element analysis of the
generator developed in Maxwell software. In the radial flux section, the generator includes a conical rotor and a cone stator. The
windings on the external stator are trapezoidal and are located in stator racks. The finite element analysis of the generator confirms
that permanent magnet magnets designed on the inner rotor have provided a magnetic flux equal to 1.2 Tesla in the air gap between
the generator and the winding of the stator. The rotor magnetic field analysis, rotor magnetic field strength, magnetic field intensity,
and magnetic field density at a speed of 500 rpm for cone structure have been performed. In the axial flux section, the generator
consists of two rotors and a grooved stator, which is obtained by simulating a 1.1 kW power with a sinusoidal three-phase voltage.
Two sections of radial flux with a cone-shaped rotor and axial flux side by side make up the generator.
