ABSTRACT
Due to their operating characteristics, continuous speed control and their reversible performance, traction motors can be considered a specific class among industrial electric motors. They are subjected to significant thermal, electrical, mechanical and environmental stresses and the increasing demand for security and reliability and the reduction of costs demand specific manufacturing requirements somehow different from other electric motors. Moreover, the development of high speed railways around the world increases the requirements on the electrical machine. These new requirements on the design and manufacturing of traction motors have a significant impact on their maintenance and repairing. Consequently, this paper deals with the requirements that a modern repair workshop must fulfill, stressing the need for personnel specialization and for the use of the most advanced technology in maintenance and repairing. Due to space limitation, the paper describes with more detail the issues related to the insulation material, since it is the motor component most stressed in operating conditions and accounts for a great percentage of the total number of faults.
KEY WORDS: Maintenance, traction motors, electric motors
