ELECTRIC MOTOR-GENERATORS FOR UNMANNED AERIAL VEHICLES
Journal Title: Aerospace Research in Bulgaria - Year 2017, Vol 29, Issue
Abstract
Permanent magnets (PM) are used in the new multi-pole electric generators. Direct connection without a reducer greatly simplifies the design and provides a long life and low weight. To improve the technical parameters of electric generators, are used PM based on rare-earth Nd-Fe-B magnets. The absence of sliding electrical contacts significantly increases life and reliability in comparison with electric generators of direct current and synchronous generators. Special attention is given to high specific indicators for the developed power per unit of weight. Additional computer simulation has been made. The results of calculating the magnetic field and moments for models of electric motors with permanent magnets are considered. It is shown that the configuration of the magnetic system has a significant effect on the electrical characteristics of the electric generator.
