Effect on the Characteristics and Control Performance due to the Ventilation Hole Design of the Traction Motor

냉각 통풍홀 설계로 인한 견인 전동기 특성 및 제어 성능 영향 연구

On this study the motor design method with fairly good characteristics and control capability as well as cooling capability is presented with considering the magnetic effect due to ventilation hole, which is installed to prevent the temperature rise. When the input voltage rises due to critical variation in traction power supply system, the final ventilation hole is presented by checking the inductance parameter with clarifying the relation between saturation of the motor core and the ventilation hole.
