A PRACTICAL METHOD TO CALCULATE TRANSIENT ELECTRICAL HEATING IN A D.C. MOTOR
A simple method is presented to accurately predict the transient rise by resistance of the copper parts of a traction motor undergoing continuously varying load, speed and ventilation. A twelve node model is used with certain selected heat transfer parameters adjusted based on heat runs made on the machine. The results of a test are given comparing the method with actual measured values on a "cyclic" heat run.
