TEMPERATURE CHARACTERISTICS FOR TRACTION MOTOR OF HIGH SPEED TRAIN

초록

Recently, as the feasibility study shows that trans-Korea railway and trans-continental railway are advantageous, interest in high-speed railway system is increasing. Because railway vehicle is environment-friendly and safe compared with airplane and ship, its market-sharing increases gradually. In the previous testing methods for measuring the temperature characteristics of electric devices, measurement was conducted only once and continuous measuring was impossible. So, to make clear the effect of temperature on the electric devices was very difficult. In this research, using the measurement system, the temperature characteristics considering speed of electric traction motor, operating time and month was measured and investigated."
