This article is devoted to the development of an electric motor with a power of 150 kW with a specific power of over 4 kW/kg for the electric-propulsion system of a small aircraft. An analysis of existing electric motors in the field of electric propulsion is carried out and the required motor power is determined. Calculations are performed based on the initial data, and a possible design and technological solutions are considered that could provide high specific indicators. To confirm and clarify the results of the analytical calculation, a finite-element analysis of the magnetic fields of the selected electric motor circuits was performed. Based on the results of analytical and numerical calculations, the optimal version of the motor is determined, for which the dependences of the main parameters on mechanical power are constructed and a design is developed with allowance for the specific indicators extremum. Using the developed 3D model, the total mass of the motor is calculated and the main parameters of the motor are compared with foreign analogues. [ABSTRACT FROM AUTHOR] |
