Abstract: As the driving part, the high reliability of the motor is the key and difficult point in the aviation and aerospace products. The article put forward a method to improve the reliability of the motor. From the motor winding processing technology, electromagnetic performance, torque, speed and resistance to limit fault conditions ability comparative analysis the winding cloth layer structure and winding each accounted for iron core slot count half structure scheme. By comparing the analysis conclusion, and consider motor processing technology, high reliability and other factors ultimately selected for the winding each accounted for iron core slot possibility of program structure design of motor winding.
