1 1 ABSTRACT The success or effectiveness for any aircraft design is a function of many trade-offs. Over the last 100 years of aircraft design these trade-offs have been optimized and dominant aircraft design philosophies have emerged. Pilotless aircraft (or uninhabited airborne systems, UAS) present new challenges in the optimization of their configuration. Recent developments in battery and m...

<span lang="EN-US">Brushless DC (BLDC) motor is widely used for various applications such as transportation. BLDC has many advantages compared to brush more compact, high robustness and simplest construction. The maintenance of this also low due absent the inside motor. For electric bicycle application, conventional electromagnetic torque because not properly designed. It faces density in...

In this paper, different electric motors are studied and compared to see the benefits of each motor and the one that is more suitable to be used in the electric vehicle (EV) applications. There are five main electric motor types, DC, induction, permanent magnet synchronous, switched reluctance and brushless DC motors are studied. It is concluded that although the induction motors technology is ...
