Consideration in the structure design of brushless DC motor for flight control

Development of the electromechanical actuation system for use in primary flight control is one of the most technologies in the path to an all electric airplane. Brushless DC motor is the key in the system. For obtained the high electrical reliability, high mechanical reliability and thermal reliability of the critical issues of this high speed large power density servo motor, the non magnetic could in special form, dual stator winding, brushless resolver and axial ventilation duct techniques in the structure design was adopted. The result was hoped. Finally, the experimental results of prototype were also offered.
