Water Cooled Induction Traction Motor for 100 % Low Floor Tram Car

The paper deals with the design of the tractionmotor for 100 % low floor tram car. Within the design itwas necessary to deal with many problems which havesignificant impact on the final product. The most interestingproblems were the conception of the torque transmission,mounting of the brake equipment on the motor body,arrangement of the motor inside the bogie, cooling of themotor or protection of the motor against the water andpollution which can enter inside the motor. In this paperthere are discussed the electromagnetic model, and specialthermal and ventilation model of the motor. The final designwas validated within the type testing
