“…The use of magnetic gearboxes is promising [22,23]. They make it possible to abandon the mechanical gearbox in favor of a magnetic gearbox and use a classic highspeed and more compact, cheap, affordable, and easytomaintain electric generator on the output shaft of the wind turbine [24,25].…”

Purpose. Development of a two-dimensional field mathematical model of a magnetic gearbox operating as part of a low-power wind turbine for the purpose of evaluating its parameters and characteristics and optimizing geometric parameters from the point of view of electromagnetic torque pulsations. Methodology. To carry out the research, the methods of the general theory of electromechanical energy converters, numerical methods of mathematical modeling based on the finite element method, numerical solution of nonlinear differential equations, and methods of spectral analysis to estimate pulsations of the electromagnetic torque were used in the work. Findings. The paper developed a two-dimensional numerical field mathematical model of a magnetic gearbox for an autonomous wind turbine. The model was developed to evaluate the parameters and characteristics of the magnetic gear, as well as to evaluate the influence of the design parameters on the magnitude of the electromagnetic torque and the magnitude of the pulsations of the electromagnetic torque. The effect of the configuration of permanent magnets, the parameters of the ferromagnetic inserts of the magnetic flux modulator and the size of the air gap was investigated in the paper. The obtained results show that there is an optimal configuration of permanent magnets and ferromagnetic elements of the magnetic flux modulator in which the maximum electromagnetic torque and minimum pulsations are achieved. Changing the parameters of the magnetic system affects the dynamics of the magnetic gear, its reliability and efficiency, therefore configuration optimization is an important task in the design, development and implementation of such systems. Originality. A two-dimensional field mathematical model of the magnetic gear has been developed, which makes it possible to estimate the change in its parameters and characteristics when the geometric dimensions change. This allows investigating the influence of various parameters of the magnetic system, such as the height of the permanent magnets and the width of the ferromagnetic inserts, on the electromagnetic torque. This makes it possible to obtain the optimal configuration of the system to achieve the optimal value of the torque and minimal pulsations and to determine the regularity of the change of the electromagnetic torque and other parameters of the gearbox under different operating modes in the future. Practical value. The simulation results indicate the prospects of industrial implementation of magnetic gaers as part of a wind power plant, and the obtained research results indicate the possibility of optimizing the design of magnetic gears in order to increase their reliability and efficiency.

This paper presents the design of a magneto-electric generator with an axial magnetic flux (MEGAP) and a double stator, which is used for an autonomous wind-electric complex. Contactless MEGAPs have the advantages of permanent magnet generators: high reliability, efficiency; and generators with electromagnetic excitation: the possibility of adjusting the output parameters (voltage, power) using an additional excitation winding. In order to meet the requirements of a stand-alone multiplier-less wind power plant, a MEGAP structure consisting of a double stator and a single rotor has been investigated. The use of a double stator design allows more efficient use of the active volume of the generator, increasing its power and stabilizing the output voltage of the stator winding. A three-dimensional numerical field mathematical model of MEGAP was developed. The model fully takes into account the design features of the generator under study, namely the presence of an axial flow from the stator winding and the flow generated by the additional winding. With the help of the model, the external characteristics were calculated, which indicates the correspondence of the developed mathematical model to physical processes. The analysis of magnetic induction in the air gap and in other structural elements of the generator under study was carried out. The analysis of the obtained values showed that the geometric dimensions of the generator, which were previously selected, are correct and do not require significant adjustments. In the future, it allows you to use the results of this calculation for the preparation of documentation for the production of the prototype. Static characteristics of MEGAP and values of magnetic parameters in all structural elements were studied. An additional winding is used to stabilize the output voltage when the speed of rotation of the generator changes and at different loads. At a relative power of the additional winding of ≈7%, the output voltage of the generator increases by ≈24%. A more significant result can be achieved by adjusting the current of the additional winding with special controllers
