Abstract-The article presents a new topology of the high-speed synchronous electrical machines with permanent magnets with the tooth-coil windings with a stator magnetic core made of amorphous alloys for prospective unmanned aerial vehicles. This is a multidisciplinary design algorithm with optimization elements, which are proposed to design such machines. Based on the proposed algorithm, calculations of several topologies were performed by using computer simulation methods. In addition, the analysis of the rotor dynamics as part of the turbojet engine of the unmanned aerial vehicle and the calculations of the mechanical rotor strength were performed. To minimize the eddy-current losses in permanent magnets, the multicriteria optimization of the slotted zone was carried out by using genetic algorithms. A cooling system was proposed, and thermal calculations were performed. To verify the proposed design algorithm and to evaluate the efficiency of the amorphous alloy, a full-sized 5 kW experimental sample with a rotational speed of 60,000 rpm was created. Results can be used to create new promising UAVs and to design electrical machines for other industrial applications.

“…En los ASIP de alta velocidad, las configuraciones bipolares son una exigencia y el inducido sin ranuras, (o con un reducido número de ranuras), y con imanes exteriores es la mejor solución (Uzhegov et al, 2016). La principal ventaja de los ASIP es su elevada densidad de potencia, sin embargo, el problema fundamental es la fijación de los imanes al rotor, que hace necesario disponer de un manguito envolvente para la retención de los imanes, generalmente de fibra de carbono (Zhang et al, 2015).…”

ResumenConsiderando que existen restricciones electromagnéticas, mecánicas y térmicas que condicionan el diseño de las máquinas eléctricas de alta velocidad, se establecen los criterios que conducen a una adecuada selección de la máquina. Además, teniendo en cuenta el estado actual de la tecnología, se presentan los valores críticos en la relación (potencia de salida)/(velocidad de rotación). El artículo se centra en los generadores síncronos de alta velocidad, especialmente en los generadores con imanes permanentes, los alternadores inductores y los alternadores con conmutación de flujo, haciendo hincapié en sus fundamentos constructivos y en sus ventajas e inconvenientes. El análisis se completa con una evaluación crítica que los clasifica, de acuerdo con unos requisitos previamente definidos. Aunque la decisión de la elección final está muy condicionada por la aplicación de interés, puede afirmarse que, en general, los generadores síncronos con imanes permanentes en el rotor constituyen la mejor opción. Palabras clave: máquinas eléctricas de alta velocidad; generadores síncronos; alta frecuencia; alternadores inductores High-Speed Synchronous Generators. A Critical Assessment AbstractConsidering that there are electromagnetic, mechanical and thermal constraints that determine the design of high-speed electrical machines, the criteria that lead to adequate selection of the machine are established in this work. Moreover, taking into account the current state of technology, the critical values in the ratio (output power)/(rotation speed), are presented. The paper focuses on the high-speed synchronous generators, especially in permanent magnet generators, inductor alternators and flux switching alternators, emphasizing their constructive fundamentals and their advantages and disadvantages. The analysis is completed with a critical assessment that classifies them according to previously defined requirements. Although the decision of the final choice is largely determined by the application of interest, it can be said that, in general, synchronous generators with permanent magnets in the rotor are the best option.

Abstract-The paper presents a study of dynamic thermal processes in ultra-high-speed microgenerators power of 55 W with the rotational speed of 800,000 rpm for UAV. A large-scale study of current works devoted to this topic were done where the main shortcomings were identified. A mathematical description of heat exchange processes in microelectromechanical energy converters with a flight time of no more than 10 minutes was developed in a non-stationary formulation. A study of the thermal state of the microgenerator operating in a short-term mode without a special cooling system is conducted. An experimental study of the heating dynamics of its active parts is carried out using the method of physical analogies. On the basis of experimental studies, the FEMM model is verified. Afterwards, combined electromagnetic and thermal calculations of microgenerator are conducted.
