Due to their operating characteristics, continuous

speed control and their reversible performance,

traction motors can be considered a specifi c

class among industrial electric motors. They

are subjected to signifi cant thermal, electrical,

mechanical and environmental stresses and the

increasing demand for security and reliability

and the reduction of costs demand specifi c

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

signifi cant impact on their maintenance and

repairing. Consequently, this paper deals with

the requirements that a modern repair workshop

must fulfi ll, 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.
